Critter, a Norton trial usually runs for 60 days. It really is best practice to run only one AV program at a time, even if there are no apparent conflicts.

FWIW, I run Avast on my 4 Gb Toshiba Satellite L305-S5937 Vista laptop, on which I have BIAB 2009, and Microsoft Essentials on my home brew Win 7 desktop DAW, which is currently running BIAB 2012.5. Both are very stable.
