Well, a couple of years ago I was hit by a drive-by virus. Just opening a website in (up to date) Firefox literally opened .exe files on my PC and infected the entire OS. I burnt my hands once - not again. This might be an anecdote to you but boy that scarred me - the idea that clicking a link could compromise my entire system like that. Even then - an antivirus program is unlikely to stop such an intrusion. It's just utterly ineffective, and I got viruses before despite having an anti-virus. Also, my anti-virus always deleted my hacktools and own programs which was a nuisance. Hence I don't use it anymore.
