My Kaspersky Anti-Virus is up for its yearly renewal again and I was wondering if I should bother? I was reading around and some people don't even bother using a anti-virus program anymore and I was thinking the same thing. I mean I really don't download anything dodgy anymore and I certainly haven't had a virus on my machine in years.

Whenever this is due to the anti-virus working(Probably not as it usually tells me if I had a virus, I think) or me not downloading anything suspicious I just don't know.

Tell me, do you use anti-virus? Shall I keep using it? is it worth the yearly sub and system hog? I'm in two minds at the moment.
