I have been using AVG anti-virus (free version) on my home computer for two or three years. It seems to work well. The free version can be used for non-commercial use (ie. at home). The software can be downloaded at http://free.grisoft.com/

I used AVG for a while, didn’t like it. I switched to avast! anti-virus: http://www.avast.com/
It has real-time scanners for pretty much everything, effectively stopping your computer from getting bad stuff on it.
Thanks for the link to Avast. I have had good luck with AVG, but there is always something else out there. I think we often stick to what we are used to, which isn’t necessarily the best.
