Norton's AV products ARE a virus. Have you ever tried removing this stuff from a computer? It's a world of hurt -- miss just one of hundreds and hundreds of files and prefs it seeds throughout your harddrive -- and the bugger re-replicates itself. It's baaaack like a movie zombie. Most viruses and malware on Mac OS X require admin user approval before they install or active. The solution is simple - be vigilant and careful. NAV at best is an expensive, messy, buggy lesson. At worst, it will damage your PC.

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 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.
