My thoughts here exactly. I'll be the first to tell you that I dislike third party utilities. This article from LifeHacker
really hits home for me (of course I primarily use a Mac but there are certainly Windows PCs in the house). With a little common sense I see no reason why people would need third party AV tools anymore. There was a time when you couldn't do without some type of AV software. But let's be honest, Windows has come a long way.
