I think the best anti-virus software is the one I use ZenOK Free Antivirus (http://freeantivirus.zenok.com/). Fortunately it´s free, the anti-virus, at least in my opinion is the best one. A long time ago, a friend of mine, was having some problem in his lab, and he tested many free anti virus softwares and they didn´t work out. When I came with this anti-virus, at that time I think it was called NOD32, he was able to clean all the virus that were spread in his lab network.
