INSTALL AT YOUR OWN RISK. Norton of any flavor risks loss of your data. It installs crap all over your computer with innocuous names that defy search and removal. Like bamboo – it also multiplies and expands. Even if you remove it – one missed tidbit can replicate the whole app again. THIS SHOULD BE CLASSED AS A VIRUS.

It's a really bad idea to list the virus definition updates as software listing on macupdate. can a moderator fix that please?

Agree. As I wrote on Jan 18, 2019: I wonder why does MacUpdate list this virus definition update and not the application itself? Virus definition updates are being updated automatically within their applications and they wouldn't be open to comments and/or reviews..

So...the techie people will get all caught up in arguing about 'definition' of the term "virus", versus, zero day, versus PUP's and versus PUA's. Followed by comments that you don't need an anti virus program on the Mac because there are no Mac 'viruses'.

The common user does not care, nor should be expected to know, the difference between viruses, PUPs, root, zero-day exploits, etc. Lay people call of this 'viruses', or malware in general. And techies are doing a dis-service by insisting that 'no viruses' exist on the Mac when they hear lay people say they have a 'virus', because lay people then feel that no protection is needed at all.

The truth is the Mac is vulnerable to 'malware' whatever word or definition the techies want to call it. Apple macOS itself includes an engine to scan for known Mac malware, called XProtect. I am constantly helping friends, family, workers, remove PUPs, search engine hi-jackers, you name it. Macs are just as vulnerable to those as Windows. Technically, they are not viruses, but to lay people, that is irrelevant, all they know is, something isn't right, machine is not working as it should.

We in the tech industry need to stop responding to end users when we hear them say "I think I have a virus' with 'No you don't because Macs don't have viruses'. It doesn't accomplish anything, recognize they are using 'virus' to describe something they can't verbalize otherwise, because 'virus' is the general label that's been around for decades. I use the term malware to cover everything and users seem to respond to that better, in that whatever it is, the intent can be termed malicious, or certainly not in the best interest of the user. It defines the problem as one of intent and mis-behavior ,which lay people can relate too, versus technical definitions over how the problem is installed, transferred, replicated, manifests, etc. , which lay people don't care, understand anyway and eyes just glaze over when techies try to 'explain' it to them.

So, OsloX, do you need a MALWARE tool? If you answer yes to any of these questions, then it wouldn't hurt, and doesn't have to be paid version, the free versions are fine, just so long as you remember to scan manually regularly.

1) You share files with Windows users, especially in a business environment (as a good 'citizen' you should help prevent the spread of Windows malware even if it can't harm you....like illness, just because you may not be sick with the flu, you can still spread germs to others and make them sick, so be preventative.)
2) You visit new websites all the time, not necessarily knowing how reputable these sites are. You're not very cautious about just clicking on licks that interest you as you browse the Net, and often end up traversing a long list of sites and links from one site to the next.

3) You are active in social media, and it's not uncommon for you to click on a link to a video, site, news story from a social media post.

4) You use your Mac for work related work, not just personal. IN other words, you take work home with you and work on it on your personal home machine.

Norton, in my experience, is okay but not as good at finding or removing PUPs or PUA's (Potentially Unwanted Programs / POtentially Unwanted Apps). If you've ever had your search engine changed in your browser without your permission, that's an example of a PUP's. If you find you are constantly getting pop ups as you browse to buy something or visit something you don't even know where the pop up is coming from, that's possibly a PUP.

Malwarebytes has been good in my experience removing PUPs and PUA's, especially search engine hi jackers and loggers. NOrton is good at finding Windows viruses, etc embedded in data files you may have received from Windows users. Malwarebytes free version is sufficient, just run it manually on a regular basis. Uninstalls very cleanly if desired, comes with its own uninstaller. Don't use any of those 'app cleaners', they can often do more damage than good. Norton comes with its own uninstaller as well and in my experience, completely removes all traces of itself.

This is nonsense. I've uninstalled Norton using Norton itself to do so and it was completely removed. A search everywhere turned up no remnants. Maybe you should learn how to use a computer!

As an IT professional – I have often attempted to remediate the damage done to user systems. I have documented Norton damage and regeneration issues before. If your experience is different – GO FOR IT. Just do't call me to fix the damage. At my hourly rate – removing Norton is a good living.

Ever heard of using the Symantec uninstaller? Removes even all the registration information (so you can do the free trial again if you want)

Your repeated identical posts are viruses. Every time someone posts a response or a question you repost the same 1/2 star rating and nonsensical "expert" opinion

I bet you have never used Norton since Windows 3.1, or you are a troll working for Kaspersky.

I think is it if you have multiple computers to update, you only have to download it once for all of them. If you have fast, unlimited Internet there is little reason to update this way.

I can't believe that with all the bad comments about this, there are over 110 thousand downloads. Does this work or not?

Yes, and if you read antiviral reviews (AV-Comparatives, AV-Test, SE Labs, etc) it is typically rated as #1, #2 or rarely #3.

Not worth posting an honest review here because you will get hundreds of "we don need no stinkin' antivirus", people who say it's the worst (most confess they have never tried it, or not since MacOS 7).

I love the "educated" reviews saying things like it corrupted their Mac DLL files or their Mac Registry (neither of which are possible because they don't exist on a Mac).

Check out the recent, honest, educated reviews at https://www.av-test.org/en/antivirus/home-macos/

I've been using Norton Security Deluxe on my MacBook Pro for about a month and it is working perfectly. No system impact that I have noticed.

I can't believe this wookie dung still exists. Who in their right ind would use it? Where once Norton Symantec products were great now they are the joke of techs. Instead of snipe hunts we send our techs on norton hunts -to find a working valuable product. They never come back...

Ha! I LOLed when I read your comment. Very witty! I remember the good old System 7 days of Norton Utilities for Mac where you got Norton Disk Doctor and Speed Disk. You could also purchase SAM (Symantec Antivirus for Macintosh). Those apps were best in class and I feel like Symantec is still riding the coattails of their former 1990s self.

I first started using Norton's antivirus software in 1994, I think. I won't support it any more. This software made itself a subscription product one day out of the blue without giving me a choice. I hope nobody will support their Mac version.
