It has no sense to use two antivirus. It's like if you to try to ride two bikes/motorclicles/cars together.
Instead of this please use one anti-virus (AVG is a good idea, and free), an anti-spyware tool (SpyBot Search & Destroy)
which has both functions (you have just to check the box that you want Extended Antivirus databases used). Zone Alarm also is indispensible.
But indeed avoid using 2 Antiviruses on the same computer- they will detect each other as virus and you may well end up having to start from Format:C (been there, done that)
