After years as a satisfied customer (and reseller) using NetBarrier X5 we upgraded to the X6 (VirusBarrier) as to keep up with new versions of OS X. In doing that we left a lean well working, and to all other alternatives, superior firewall to a large software with a lot of good stuff* we did not needed. This did not represent a problem (other from one or two clients messing things up) as VirusBarrier is easily configurable. What was not obvious in the transition was that we were forced into a subscription system. Earlier the subscription was only about virus/malware definitions, now suddenly (and very quietly) it was the firewall itself! The Intego site is no clear at all about this; 'buy a protection' all over, not 'pay for a subscription'. In the future we (and our clients) are to fork out 60% of the initial cost yearly (in a one year plan)! Even strange companies as PGP (now Symantech) has a perpetual alternative. Worse, the reasoning for this is absolute ridiculous, Intego site; 'using out-of-date security software is dangerous'. This becomes completely nonsense when the Intego protection just stops if you forget to pay!! That must be much worse than being out-of-date. It is only for the $ as I see it. So, now back to reinstalling latest NetBarrier on all machines an clients, and stop all planed upgrades. *although in a test run it catches only 4 out of 15 virus (ClamXav detects them all in any package) Worm.BadTrans.B1 FOUND W32.Elkern.C FOUND W32.Elkern.C FOUND W32.Elkern.C FOUND W32.Elkern.C FOUND W32.Elkern.C FOUND W32.Elkern.C FOUND W32.Elkern.C FOUND W32.Elkern.C FOUND Worm.SomeFool.Z FOUND Worm.SomeFool.Z FOUND W32.PrettyPark FOUND Worm.Sircam FOUND Worm.Sircam FOUND Worm.Sircam FOUND

Version 10.6.13
19 September 2019
I would not purchase this product and being a past user as of 9/17/19, am advising folks looking for a mac antivirus solution not to consider this product. I used this product exclusively on my Mac’s thinking it was the best because of the marketing line “developed by a company that knows Macs”. I had it for multiple years until this week when my Mac got infected. X9 happily reported nothing found during full scans, and when I contacted the company they stated their product did have the capability to detect my infection. Well, it did not, and now I’m left with having to rebuild my Mac from scratch and try to extract my photos, documents and video’s from my infected hard drives. There is a reason they say – you get what you pay for. Don’t buy this product, go buy from an established company who support multiple products on multiple OS’s. Search online for the PCmag review, thats an honest one.
Version 10.9.18
19 April 2019
As of TODAY, v10.9.18 is officially available to all. At the moment, NetUpdate is clueless. But it is the version at Intego’s Downloads page. So have at it! (Previous to today it was in beta, intended only for testers).
Version 10.9.18
13 April 2019
Certainly the best I've ever used. It's unobtrusive, reliable and works pretty quickly, without demanding too much of the CPU. I've been a customer for a decade or more and I have never had a problem with it.
Version 10.9.17
12 April 2019
v10.9.17 was released in November, 2018. If you own Internet Security X9, you most likely already have this update. (Includes VirusBarrier 10.9.17 and NetBarrier 10.9.6).
Version 10.9.17
23 October 2017
Renewed for three Mac. Cost $79.00. Received email with offer for new customers at $54.00 ! Have been customer for at least ten years. Virus thing I don’t care about, does have a good firewall that can be change to location.

Version 10.9.5
15 January 2016
Intego's products are terrible. I put their Internet Security bundle on my Macbook Pro a couple of years ago. A month or two later it would start to randomly slow down to the point of being unusable, and then occasionally freeze. But we didn't know at the time it was Intego's fault. I spent hours at the Genius Bar having those folks run every test they could think of on my computer. They even replaced my logic board under warranty, thinking that might be the issue. Nothing resolved it. Finally the light bulb went on. I used an app uninstaller program to delete all Intego products from my laptop and the problem disappeared and never returned. Intego didn't protect me from a virus, it WAS the virus. Stay away, horrible software you don't need to begin with.

Version 10.8.4
22 January 2015
Detailed malware detection test results are regularly posted here for nearly 2 dozen products, free and paid: 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.

Version 10.8.1
17 December 2014
The debate rages over whether or not Mac users need any Malware protection. It is most confusing and depends upon which magazine or website you read! I have, over the years used various versions of NetBarrier and VirusBarrier. I have tried the "Free" Sophos and Avast and both can be problematic without changing some of the settings. This suite is easy to install, runs quietly in the background and appears to have no impact at all on Mac speed.. It's GUI is a little 'loud' with garish icons and weird diagrams and graphics but easy to follow. There is a stated clash with Drive Genius 4 but it seems to be OK as long as Drive Genius is installed first, followed by Internet Security. I think approx. $60 Australian is not a bad price. I assume there will be a fee to renew definitions yearly. Moral: You get what you pay for!
