I tend to go with Norton/Symantec for most systems, but I still have faith in Kaspersky as having the best detection, only I've had performance issues with some apps with KAV installed. That's why my current answer to the question "what's the best anti-virus in 2010?" is another question, "Best for what? Who's the user? How knowledgeable are they? What are the risk exposures?"
A friend of mine recently got two computers infected with a new variant of the annoying "Internet Security 2010" malware, which can be tough to remove and I was the one stuck doing it, so I'm as appreciative of good AV's and safe computing practices as anyone!
I've been using KIS for years now, but recently I've been noticing Norton AV has been detecting quite a few critters KAV seemes to miss lately.
