I manage several dozen PCs and in 10 years have never seen a virus on any machine that had an up-to-date AV program of any kind.
Back around 1998 or so Melissa got through a lot of scanners. Prior to that, people didn’t take the potential very seriously.
I’ve managed several hundred PCs and dozens of networks over the years. They GET viruses even with up-to-date software. The software MITIGATES the virus, it doesn’t always PREVENT it.
Firewalls are your friends though....
And to appease the people slamming “unix-like” systems as “no better than anything else” - well, they PASS VIRUSES TOO, just like windows machines can do. What they DON’T do it become infected, or if they do, only at the user level. (Assuming you’re not using root as your local user login and if you are, then... you deserve what you get, lol)
