I've used AVG for years with no real issues. I do believe the constantly highly rated one is pc-cillin from Trend Micro. They also have a free online scanner that's top notch as well.
I've never used their installed product, but people I know in IT departments always seem to run this on their personal stuff. Might be worth a look. Google for Trend Micro and you'll find it.
