Very interesting thread.. heh!!

I can see both views, but for any kinda person using a computer in a network or on the internet cummunicating in any way with others, you are not depending soley on your own knowledge and the right way of doing things...

Let say you educate all the employees in your company to not ever open mail from "untrusted" sources. ...now you are safe, so safe you don't need any AV??

I wouldn't think so, they cummunicate (in most companies at least.. heh!) with others that you as an admin have no control over at all.. ! If your customer has been compromised, and this customer now is sending for example an infected email or document to you, this "trusted" source could now potentially infect your whole network.. !

I would say in very rare cases, where you don't depend on anybody else, or you are not hooked up to a network, you could safely be without any AV, but other wise it would easily be asking for trouble...

Anyways, just the fact the guy who initially wrote the question was in fact infected with a few viruses already there tells he needs an AV solution!
