I am curious enough to ask this question. Is Internet Security really that important? I can see the use of a firewall for sure but, I have never had any problems like a virus attack or anything like a serious spyware problem in all the years I have computers. But, obviously I know people who have had these problems. So do I really have to have software running that protects me against all these things that have never affected me personally? I suppose the prudent answer is yes. However it takes up ram and disk space for something that I don't seem to have had a use for.

Thinking of being prudent as always, my guess would be to have both a minimal Anti-virus and spyware programs on the computer but, not resident in memory all the time. That way I assume they would be there if I need them but, not wasting memory and any other resources when I don't them. Thoughts please?
