Norton AntiVirus for Mac12.3

The latest test results on the site posted below by Mcr are over two years old (July 2014).
For more recent results (March 2016) look here: http://goo.gl/rvzQxa

The testing was done by this site: http://goo.gl/naqw0F
That site has a LOT of useful test results, including spam detection.
NOTE: Not all software tested is Mac software, so be mindful of that.

Does anyone else find it suspicious/alarming that only 4 out of the 12 antivirus companies tested in 2016 are from the USA? https://goo.gl/bhOauU

Not very user-friendly, but in general I am satisfied.

Detailed malware detection test results are regularly posted here for nearly 2 dozen products, free and paid: http://securityspread.com/detection-rate-results/ These are very detailed, showing EXACTLY by name for each malware/virus if it is detected or not, for each product, then products are ranked 95%, 85%, 75% etc based on detection rates. Historical results are maintained so you can compare over time, and you do see product results change with each test (done every month to every 3 months depending on whether there are any new reported malware in the field, and a sample can be obtained for testing). I've done a bit of research on the site and tester, to make sure it was not one of those 'sponsored' sites by a vendor that are made to appear as objective, neutral reviews. The fact that the product rankings change constantly AND that the results are very specific and listed in detail, further support that this site and the tester are very objective. In fact this is exactly the kind of site and test results, that vendors DON'T want you to see, even the ones that do well on the test (because no product is 100%). I am posting this to support the Mac Community. When we are all better informed when it comes to this important area of security in this day of cyber threats, we all benefit. Education and information is the best defense, (as with so many things in life). For example, if someone uses MacKeeper because they don't know better, then in some ways the community failed for not getting the word out. If after doing some research and being advised not to use MacKeeper, someone still chooses to do so, then you can't help that, but hopefully it wasn't because there wasn't information available. My aim is not to support or dissuade anyone about a particular product, you pick / use or don't use whatever product you want, and live with the consequences, just remember that your decision can effect others, by virtue of whether you are part of stopping the spread, or being a part of it. I highly recommend you don't just look at the current results, but look at the past ones as well. You WILL see trends, with some products consistently doing well and others not so much, and some moving up and down. Remember, an A/V product rests on two main things, the scanning engine AND the malware database. A great engine can be crippled if the database is not updated in a timely manner. Conversely, a vendor that does maintain a current database might still not be effective if the program itself is buggy. This site only ONLY addresses virus detection results, it does not in general make any conclusions or post results regarding performance, installation, support, UI, etc.

The version advertised here is completely late! The current version is 12.7 (57) See: http://cl.ly/YAeO/Norton_AntiVirus_12.7(57).png In addition, the antivirus itself is very good! I Like him, further increasing the protection of my Mac

I've always been happy with NAV either on my PC and now on my Mac. The only problem seems to be the long time a full scan takes. And about system speed, it's great compared to other AVs on the market. By the way, if you search the net, you might find much more cheaper prices for this software.

Nowadays there's a good choice of antivirus software available for the Mac. Many of them are Free. They do just as a good job at detecting viruses as Norton AV does, and don't invade your HD with useless files. Stay away from this!

Norton is the first thing I UNINSTALL from any new computer that comes with it. The most useless bloatware you can find. Now on Mac? Thanks but no thanks.

Upgrade price is $29.99.

Active scanning is STILL a problem on Mac. Not specific to Norton AntiVirus...but to ANY antivirus. Disable in production environments, or users will hunt you down, shoot you in the head and again in the chest and drop your limp body into the sea. Don Montalvo, TX

I purchased NAV 11 back in 2008. I have done yearly subscription updates (like an idiot) since then. I had a HD failure and decided to take the opportunity to do a complete reinstall on my mac. When I got to NAV I discovered that the original (last downloaded) installer does not work with 10.6 even with Rosetta installed. So I contacted Symantec for assistance. Big Mistake!!! The guy began by explaining that the "software" only last 1 year. OK I get that the subscription is only good for a year but I am not talking about the subscription. I need to install the software as I am not going to purchase a new sub unless I know it I can install the software. So I ask if I am I supposed to re purchase the entire product if my system fails 13 months after I purchase the orig even though it's the same version? According to the NAV guy yes you are. He went on to explain that because it is security software it's only good a year??? I guess even if we are still selling the same version! I was well aware I would have to purchase a new subscription but I am not going to keep dropping nickels in the norton rip off machine.

I use Norton Anti-Virus as part of Norton Internet Security for Mac. I am posting a review here because Norton Internet Security for Mac doesn't seem to be on Macupdate. I really don't understand the negative reviews. This program works great! There is no slowing of my system at all. I am fairly new to the mac and have a new macbook pro. I know there is not supposed to be any viruses on the mac but I was concerned about all types of threats not just viruses and NIS for mac fits the bill perfectly. I tried Virusbarrier x6 by Intego and it noticeably slowed my system down unless I didn't run it live. If you don't run it live, what's the point. NIS is also very customizable as well.

I posted a positive feedback on another download site: "If you have really rewritten it and it really does scans for web threats too, why not provide a free trial so people who have your bad image in mind may change their minds after testing?" Sounds simple yes? Believe or not, some official guy, very high official replied and he said it makes sense and they will try to provide a trial. 1-2 YEARS ago. Yes, Mac security threats are becoming very big deal, the simple trojan stuff already out there. Issue is, do you want to pay $43 to test a product? Every single Antivirus has a trial because of a basic reason: They won't work perfectly on every system out there. It is a technical issue based on the "ring" they run and the low level routines they use. Even "Intego" who ships equally expensive products with expensive updates has decency to provide free trials for their every single product. If you have a specific threat, for example some "click on everything and run" type of user, I suggest every other product which has some testing ability.

It's incredible that for as long as everyone has known Apple was developing OS X 10.6 that Norton has not updated their virus application to support it. I would recommend that everyone switch to Virus Barrier X5 which has been updated.

LIVEUPDATE & AUTO-PROTECT NO LONGER WORK IN 10.5.7!!! Since I updated to Mac OS 10.5.7 on my iMac and my MacBook, the Auto-Protect and LiveUpdate components of Norton Antivirus 11 (NAV) no longer work. LiveUpdate automatically or manually checks for and downloads new virus definition files and updates for all the components of NAV. Auto-Protect automatically scans my system in the background looking for viruses when I am on the Internet, downloading email, or using any kind of external disk. With those two components dead, Norton Antivirus 11 is now COMPLETELY USELESS. And I cannot download a fix because the utility that downloads such things is what needs to be fixed! Nor can I find a fix to download from the Norton or Symantec websites, which are possibly the worst customer support websites in the software industry. Here are the two alert notifications NAV gave after I tried repeatedly to uninstall and reinstall it: "Norton AntiVirus Error. Norton AntiVirus Auto-Protect could not continue. Please run LiveUpdate or reinstall Norton AntiVirus and restart. (Code: 10)" "System extension cannot be used. The system extension "/Library/Application Support/Symantec/AntiVirus/NortonAutoProtect.bundle/Contents/Resources/SymApComm.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update." Systems Info: Late 2006 Intel Core2Duo 2.16 GHz 20" iMac with 2 GB RAM, and Late 2008 Intel Core2Duo 2.4 GHz Unibody MacBook with 4 GB RAM, both now running OS 10.5.7.

well it looks better and its clear what its supposed to do. BUT why does autoprotect sometimes take 100% of the cpu (according to istat pro) and when it does this the fan on my laptop goes into overdrive, I have been thinking for a while about uninstalling

Updated to 11.0 when renewing subscription and ALL applications including finder have ground to a near STANDSTILL! I turned off auto protect and anything not related to outgoing email and got the same thing. Then I ran the UNINSTALL program in the Symantec folder and everything is running faster than it ever has before. Now I need to find some other APP to protect my hapless PC using clients. Hopefully I can find one that doesn't grind everything to a halt. Sorry I wasted my money on NAV. again...

How about fixing NAV 10. Somewhere between original NAV 10 release and v.10.1.2, the application became more buggy, slow and prone to paralyzing Tiger with auto-protection on.

At least it works and find virii. It is not always the case with VirusBarrier (X.4 or X.5) : I have a folder full of (win/macro) virii : NAV 11 found them all, while VB only found 5 of 21. The GUI is quite simple and very easy to use. So far, I didn't got any stability problem nor slowdown. Sure, it's not as fast as VB to scan a full disk, but really, how often shall we do that ? Scanning the home directory is enough in most cases.

I have had Norton for years and with Tiger it takes hours to scan the drive. I ‘switched' to VirusBarrier, drive is scanned in minutes! Yes I called Symantec and the man from India wanted to have remote access to my computer-NO WAY.

I purchased the upgrade online, and when I arrived at the order completion/download page, there was no download button. I tried both Safari and Camino with the same results. I received a confirmation email for the purchase. When I contacted Symantec Customer Support, I was told the order was still in processing, and I would receive a second "confirmation" email with a download link. Anyone else ordered the upgrade online and seen this?

While the need for Mac antivirus software is minor compared to in the Windows world, I installed NAV 11.0 Universal in order to have one more layer of safeguarding since I receive and pass along many files from Windows PC users, many of which are not tech-savvy. I am not worried about getting viruses on my Mac but appreciate the increased level of PC virus detection in NAV 11. As far as NAV 11 itself... it's Universal, it's much faster than NAV 10, and in a day's testing it doesn't seem to have any performance hit on a 2.16 GHz C2D MacBook. Especially considering Symantec's past history with Mac products, it seems that they've finally put out a decent product with NAV 11. While the need is slim for Mac AV products, NAV 11 seems to be a viable contender. Granted, I've only used it for a day but in that day there has been 6-8 hours of use involving having multiple Adobe CS3 apps running during a scan and performance has not suffered. Only negative is that the interface, while greatly improved, is still not entirely "Mac-like" (i.e. absence of Cocoa toolbars). Minor gripe. Four stars.

New version is troublesome. I believe the latest version is actually 10.1.2 and this latest update has made NAV even more problematic than previously. Most of the time I have had to disable auto-protection in order to be able to eject disks, disk images and other volumes. The latest version, with auto-protect on, now bogs the system completely when a disk image is mounted, necessitating forced _restart_. NAV will not force quit and force quitting the finder does not help....spinning,spinning beach balls..

We installed this product on G5's running 10.4.6. Then the shared documents (projects) feature of Archicad no longer worked. We uninstalled NAV X and then Archicad started working again.

Most of these comments are not helpful, if you run a business even it is on PCs you do not want to be sent viruses by Mac using colleagues. If you use Macs then you can lose business from PC using clients who you send a whole load of viruses to even if they don't effect your mac. If you are just an individual mac user then maybe theres no point or you will use the freeware alternative, good for you Maybe the whole virus thing is a con, maybe the poacher and the game keeper are the same thing I dunno. What I do know is waving around the magic "I am on a mac it doesn't effect me" is madness. I have run websites for years offering free advice, all very nice til I was hacked by a 14 year old Brazilian hacker who thought it was funny to be destructive. You never know what might be around the corner.

securiy enhancements ??? Basically this means that having Norton AV installed is more of a threat to your Mac than not having it installed at all, as there are no known viri for the Mac. Sad...

I've had 2 mac viruses (OS 7) and tons of PC viruses in attachments, which I am interbreeding to see if I can create better more productive software than mikrosoft. preliminary results are looking very promising, I can relyably bulk email coleauges and successfully wipe disk drives

just one comment: i have never had a virus since a i have my mac....... useless......

Complete garbage, causes more problems then it ever prevents. Not worth 10¢.

I purchased Norton AntiVirus for Mac 9.0 from buy.com on 4/12/05. On 4/28/05 it became obsolete with the release of MacOS 10.4. Symantec released NAV 10.0 on 5/12/05 to be compatible with MacOS 10.4. I tried contacting Symantec customer support by email beginning 5/12/05 to to see about an upgrade from 9.0 to 10.0. I received no response. Finally I reached a customer service rep in Bombay, India, by phone on 5/31/05 who said that because I had not purchased NAV 9.0 from Symantec directly I would have to pay for the upgrade. This is, of course, an outrageous policy and the reason why American business is steadily declining. I urge anyone who is considering buying a Symantec product to look for an alternative product from another company.

I have been using it for 3 days. I have also used NAV 9.X and VirusBarrier before. NAV 9 was a pain for my system but this new version really shines. It is considerably faster then its predecessor and has some interesting new features. I haven't noticed any slowdown since i installed it (PB G4 1,5ghz/ 1,5 gb RAM). Better than VirusBarrier when it comes to antivirus definitions update rate (1 week VS 4 weeks). Installation is very easy and the program lets you do the stuff you want do do; it doesn't get in your way.

To be honest: I was no fan of NAV 9, but this new version 10 realy works fine! I used Virusbarrier before, but NAV correctly scans all mounted disks: CD's, ZIPS etc. As I get a lot from clients this way, I like an automated scan.

Works quite well and remarkably better than the previous version. The problems concerning Distiller and pdf files seem to have vanished. NAV 10 is not that slow for me, maybe because I switched off the scanning of stuffed files...? (I don't really need that.) IMO, the best antivirus out there at the moment. Let's help keeping our Windoze neighbors clean, until the first real OS X virus appears... :-)

For me this is a great softwate too!!!

Completely useless as there are no viruses for mac. More likely to cause you trouble and definitely can't solve anything. This is a company that scare people by bending reality into words that make their profit.

At one time there used to be a Norton Utilities and upgrading made sense as you would reap the benefits of a total system maintenance package, but now that is gone and you are forced to deal with just AntiVirus. The appeal is now gone. I don't hate Norton, but they are far from where they started and have forgotten their roots.

This software is only good if you have the right software and hardware other wise is will eat up your system. Back up you computer before you install this software.

Run... very, very fast in the other direction when you seen this software in your vicinity.

AV 10.0 is good as it could be! Work fine and it does a job well !!! I am "fussy" guy but I can not say anything negative about this software or company!

Avoid Symantec. They are the devil. I have had my hard drives butchered from their software. Peter Norton would not be happy to see what happened to his company.

Agreed, NAV and Utilities in general have caused so much grief I've ditched it, back-up on a regular basis and try this for Virus Protection (even though it never finds anything it's free): http://www.macupdate.com/info.php/id/15850

In my (considerable) experience of maintaining a variety of Macs for a law office -- I have found that Norton AntiVirus CAUSES more problems than it pretends to prevent or resolve. It scatters crap all over the directory, is intrusive, pervasive, and INEFFECTIVE. Causes crashes, slows access, and its 'update' feature causes pure hell in a real production environment -- even with broaadband. WE CANNOT RISK NORTON in our real office environment. It offers not the promised protection -- but a never ending nightmare of 'issues' that will make Windows look like a blessing.

Why would you put this garbage on your computer? It won't protect you from anything. The only thing it might do is protect Windows using friends from their own viruses. And it has the added value of messing up your computer. What a combination. Anti-virus software is always after-the-fact, anyway. It couldn't protect against a Mac virus until after one actually exists, because it couldn't know about a virus that hasn't been written yet. Instead of buying this junk for your computer, buy a clue instead.

I just upgraded Norton and got something in the upgrade that has completely screwed up my OS 10.3 so bad that I got a black veil dropping across my screen then the spinning color wheel that won't quit. I've tried uninstalling Norton but it won't let me do it. I thought the program was great until this last upgrade!! Now What?????? My computer is a real mess!!! 2/13/05

The Mac Community needs another "true" player to provide us with this type of software. Granted, I've been with Norton ever since Peter, but it's petered out and lacks the commitment and care that the Mac Community both appreciates and deserves.

poorly implemented; just bad software man.

After I received this update, my computer will not download certain things from the net. Many applications crash that never have before. Thanks Norton, it looks like another full recovery.

Norton destroyed my Mac OS 10.2.8 completely. To save all my data and apps I had to buy 10.3.5 and re-install the OS from scratch. Never again!

I have not any problems at all. Easy to use. Certainly, seems to have fewer problems for others as well who use Virex 7.5X.

HELP! after having so much trouble with antivirus which caused horrible kernel panics i wanted to uninstall that bad software. but hey... it`s impossible! the uninstaller doesn`t find any norton application on my computer. in the documentation this kind of problem is NOT mentioned. so, how can i uninstall this piece of bad software which hasn`t satisfied me?

Norton (as a company) still sucks. After many frustrating years using Norton products on my Macs I am furious as ever with this company. I have posted reviews before ripping this company (and they were justified) and now I have another. After purchasing Norton AV 9.0 for my Mac I had to go through Norton's "Rebate Dance" to get the promised rebate. I despise purchasing anything that you have to send in for a rebate but I was in a hurry and needed an AV update). Anyway, I went through their "rebate dance" and provided everything they required (original disk, UPC code, proof of purchase, purchase receipt). I purchased my update from Fry's Electronics in Phoenix. They are good enough to give a Duplicate Receipt for anything that they sell that has a receipt. I have used this duplicate receipt many times in the past for rebates from other companies and have never had a problem with it. Even though it shows everything needed and states the rebate on the register receipt.. NORTON and only NORTON will not accept this.. They don't state that up front, I had to wait 6 weeks to get a tiny post card in the mail telling me my rebate had been denied because I did not show "proper" proof of purchase. Even though I had sent them the FOUR ORIGINAL items they requested. Now I don't have them any more they tell me I can RESUBMIT. But since I don't have any of the items required any more (since I had to send in the originals) and they did not give me ANY reference numbers to resubmit to.. how in the $@%#$ am I supposed to do that. All I can say is NEVER AGAIN NORTON. If you need my $30 bucks that bad you can keep it and then shove it where the sun doesn't shine. Why do we put up with these rip off companies people. You buy their product, you get NO tech support without paying additional. They steal from you with their rebates (because they know most people will not keep jumping through the hoops) And they just keep putting out inferior products year after year. All I can say is NORTON.. a pox on your house !!! NEVER AGAIN. DOES anyone know a better AV and Sytem Utilities than Norton. I swear I will burn my copies of Norton programs if someone can point me in a better direction. I am sick of lining these companies gold plated towers with my hard earned money.. only to be ripped off time after time !!!!

i can't seem to disable norton anti virus on my mac (osx.3.5) . can anyone tell me how to do it?

- Norton utilities crashed my computer and Norton anti-virus do the same bad thing with kernel panic. - NAV Auto-protect and other paranoïd preferences (the better way to slow your Mac) keep working on your system even if you disabled it! - NAV puts a lot files on your HDLibrary/ Home Library/ and the worst: SYSTEM. Conclusion: impossible to remove some of these files + Kernel Panic when I launched some utilities apps. Enjoy Norton Products!!

Actually, the autoscan on mount has the side effect of finding damaged files. Very useful in that aspect.

this antivirus it very bad. I can´t install it... lot of errors and very bad support

Apple Macs have had there share of viruses. If Macs had absolutely no virus theats, there would be absolutely no virus detection or removal software. But because Macs have had viruses and will again have viruses as well as currently have viruses, there is a software market for Mac Virus protection. Norton works well and so does Macaffee's Virex, and so does Integos Virus Barrier. i use all three plus a couple of others. I do not rely strictly on one. I have caught viruses from the internet and had them instantly removed, and most of the time the 3 software progrmas mentioned above have all caught them and removed them. So it is worth the effort and expense to install this one as well as the others. Dont rely on just one. Even if your system is not compromised by a virus, or affected, it can still harbour one and pass one around. Even if it is a pc version of a virus.

Yes it is an updater. Virus on Mac... Sure none that works for mac, but we harbour them, and pass them on, like the @netsky that comes as .pif attachements in mails. - Virex 7.2 does not find these, at least not while downloadin the mails. But Norton AV 9.x does, and removes them on the fly. So to spare the pc friends, use Norton AV.

Mac OS X has NO viruses. PERIOD!! And I have no intentions on using my CPU time to assist Microsoft in cleaning up their own sloppy security. If the need for a virus-free environment is important for some people, then they should move to Macs. Otherwise, let 'em burn with their ill-informed, lemming-like, decision. Secondly, Norton is notorious for poor quality Mac software. I have Virex (downloaded free from Apple via .Mac) if there should ever be a Mac virus. But, I'll wait until then to run it.

Isn't this a virus update and not a update for the application?

Symantec does not understand that the people that would benefit the most from this application are in the enterprise. NAV 9 is still based on an individuals machine. It does not tie into Symantec Enterprise software so there is no tracking or forced updates or even the ability to verify that an update will work prior to updating it. There is also no reason that this program does not use the same definitions as the PC version. When the PC gets an update, the Mac version should be able to use it. Lastly, virus software needs to be hidden from the user. If a user can see it doing anything, they will get irritated. I ended up having to create cron jobs to avoid the LiveUpdate Window. I think the best thing I heard about that window was, "That is the ugliest design I have ever seen on my computer." I am thinking that could be reduced to nothing and be a good start. The only thing I can say is that so far it has been fairly stable with system updates. I never thought I would be able to say that about anything from Symantec, but they did pretty well with this one. Now I expect it to fail with 10.4, but unless Apple gives them a ton of details ahead of time, they can only do so much. Still, much better than Virex that took years to get a product that was useable in terms of actually giving the features any virus software needs like on access scanning. Sophos is still the best, least intrusive virus software for the Mac. Not to mention that Sophos was the only application the actually found almost all the viruses that I put on a machine in various ways. There is a dated detailed review that I wrote at http://ceti.acs-inc.com/evaluations/virussoftware.php

What Viruses?

I find this sofware to be a pleasure to use, it's so simple and user friendly. I have used many anti-virus programs but I find this to be the best... well done symantec keep up the great work.

Essential on Windows, I prefer Virex on a Mac. If NU is bad, NAV is pretty good anyway.

I don't understand all the negative reviews. I find this software very usable and reasonably priced, comparable to the other virus software. I've had no problems with the program. The only comment I agree with is that sometimes it seems the updates for new systems do take longer than I think they should. It appears telling that most of the extremely negative reviews are from anonymous posters. I've always been taught not to trust someone's opinion if they're afraid to identify themselves. Sometimes anonymous bad reviews are posted by people associated with a competitor, though I doubt any of the major virus software companies would stoop to this trick. To sum up my opinion, it's a very good program for detecting virus's (though no software is perfect).

on the plus side side for Norton AV, there is one known trojan for Mac OS X. On the plus side for everyone else, the trojan was made just to display the vulnerability, is not malicious, and Apple is aware of the hole and has a fix coming. The only point I can see in buying this software is if you feel like windows people shouldn't need to bother downloading patches. But guess what? They're going to get viruses and worms and trojans anyway, so they need to download patches anyway, which makes this software 100% useless for not just mac users but everyone. Symantec is brilliant... they're offering useless software at $70 per user, and people buy it. God I wish I had customers like that.

I use the hole package with 10.3.3 on PB17" and G4 1.42 without problems. also norton's firewall on both machines through airport extreme.....

So this is the update that makes NAV finally work with 10.3?! And how long did it take them this time? Half a year??? Buyer beware!!!

I've had to uninstall Internet Security 3.0 (which contains NAV) from all my machines because it conflicts with Panther. Still no patch as far as I know. Certainly I couldn't find one on the Symantec website just yesterday. Brother Mugga

>> "Kill the latest viruses"

Mac viruses are rare so this isn't a "must-have" like on a PC, but since this version also protects against PC viruses it makes it harder to inadvertently forward a virus to a PC user. MS Office users might have a higher risk of having a virus execute (Word macros, for example) but on a Mac the chance is still pretty low. I keep NAV 9.0.1 installed just as a precaution, although I wonder if it's to blame for a few kernel panics with a Symantec .kext file as the culprit.

Norton has ALWAYS been terrible running software,it conflicts with EVERYTHING! Not to say that their emergancy boot disk isn't an essential utility to have, but their anti-virus and firewall ALWAYS causes problems. First of all you have a Mac...WE DON'T GET VIRUSES! Don't by into the hype that you need anti-virus software (that's bloated and will conflict with EVERYTHING!) and a third-party firewall. There's a great firewall already built in OS X, and it works fine. For the truly paranoid, buy a router with a hardware firewall (Belkin, under $50) and you'll be totally invisible to the net (I'm truly paranoid and I have one! LOL!). I guess you can apply this review to any other firewal or anti-virus program. You just don't need them...

I uninstalled, reinstalled from the CD, and then ran Live Update. Still, nothing works. The software is not checking as it should. For example, I insert a CD and nothing happens. This is pathetic.

Those who have problems with updating have probably moved the "Norton Solutions" folder from its default location which is the "Applications" folder. It is a bit sad that you can't arrange things in the Applications folder without having trouble with updates.

What update? I get a generic app that doesn't run or update the existing Norton. Any ideas on how to get a real update so that it will work with Panther?

Bad update :-( Since I have download the version 9.0.1 with LiveUpdate I become following dialog box every time when I start my mac and login as user: "Norton AntiVirus AutoProtect could not continue. Please reinstall Norton AntiVirus and restart." That´s *very* badly.

Why need virus checkers for OSX?????

I bought 9.0 based on its claim to defeat Windows virii. Unfortunately, it doesn't integrate with my e-mail client (Mulberry) and it caused or contributed to over a dozen kernel panics. This seems to be a consistent problem with Norton applications on the Mac, and a reason why I seriously doubt I'll ever spend money for them again. *Any* of the other Mac utilities out there do a better job and cause less instability.

Horse manure. I have NAV installed on my Macs and I have the Apple OS X firewall running on them with no issues whatsoever.

Since installing this product Norton has seen to it that their software disables the internal firewall that's built in to OSX...It was working before this install. Is this so you'll have to buy their other products as well? I'm not impressed one bit. Now how do I turn on the internal firewall again? Keep getting the message that there is another firewall running???? How can this be when there is no other firewall installed on my system???? Symantics on-line help is a joke to say the least. The only way to contact tech help is by phoning...there is no e-mail support.

You do not need to uninstall Norton Utilities to allow Quark to create PDFs, you only need to disable NAV temporarily when you wish to distill a postscript file. Easy, though a pain in the butt. Has anything been done to address this problem?

Thanks to Anonymous for the comment about NAV interfering with Acrobat Distiller. I have been going crazy trying to figure out why I haven't been able to write a PDF from Quark XPress (running in Classic) any longer even though it previously worked fine. I thought it must have been some incompatibility between updates to OS X and Classic. When I uninstalled Norton Utilities and turned off NAV, things are now working perfectly! I am becoming wary of Norton in general and NAV in particular. I was using Norton Systemworks 3.0 for OSX.

Maybe someone finds this useful: NAV 9 interferes heavily with Acrobat's Distiller 6, causing the "distillsave" error and creating no pdfs. After deactivating NAV's auto protect feature, everything seems to work again. Seems that NAV cannot distinguish a pdf from a potential virus... very disappointing.

While I would like to see more controls of actions and behaviors out of the box, this version has worked better for us in the OS X environment across multiple hardware setups.

TERRIBLE!!! Better use Virex if you're a .mac member.

Maybe there are not viruses for Mac OS X, but there are known viruses for Offices's suite (e.g. macros) that could affect the application and not the system. An antivirus able to detect that is in any case useful, at least to prevent spreading (unwillingly) viruses to other people e.g. through mail attachments. That's enough of good reason for having antivirus even on OS X, at least for myself.

I still don't understand why Mac users are so concerned about virus protection. When was the last time that we had a real bad virus? SevenDust, Autostart, whatever? Mac OS X is Unix-based, just how many Unix viruses are there? Furthermore, anything from Symantec, whether it's Norton Futilities or AntiVirus, is more likely to cause problems than it solves.

When I tried to install Norton AntiVirus 9 beta, I got an error message that said it failed to mount -error 95- (no mountable file systems.) Guess I'll look elsewhere for Virus Protection for my new Dual GHz Mac.

Wow. The first day I use it, it finds a virus in mail.app's junk mail box. Too bad it couldn't repair it.

It's not 6,8 mb, but 14,2 mb... And it doesn't recognize all Mac-virusses (I tested it!). It also doesn't scan compressed files, only Eicar he found compressed... All 14 other compressed virusses were overlooked... It also slowed my 800Mhz 17" iMac terribly... I don't believe these things are only there, because it's a Beta... Or are they?

I have installed v7 for X and now v8.0b1 and v8.0b2. Installation was smooth as expected from Symantec. It checks files, programs, etc., all as expected.

I have generally been quite pleased with Nortno Utilities/ Anitivirus /Firewall under Pre-OSX but the Norton suite of products for OSX are clearly not ready for sale. Norton Firewall won't install period. I get "installer cannot create folder" access denied errors. Norton antivirus installs but gives persistent trouble and cannot test many regions of the disk. None of these problems are described in the knowledge database at symantec. I would definitely NOT recommend this product to anyone.

Quits unexpectedly every time I run it.
