No one here said they where immune to getting a virus due to common sense. Unless you are using a behavioral (i.e. Threatfire) or heuristic scanner then you are always playing a catch up game. Look at the great viruses\worms\trojans of the last ten year Love Bug, Code Red, Explorer, Sir Cam, Nimda, Klez, I Love You, Melissa, SQL Slammer, MyDoom, Netsky\Sasser, Leap-A (Mac), Storm, CIH, Morris, Concept, Conflicker. With the exception of Concept, all of these could easily be avoided by using security best practices, keeping patched and a little common sense.
Common sense, firewalls, daily or even weekly patching of all applications, locking down your system and using UAC are all more important than an anti-virus application.
