I think Avast is the best Antivirus software. I have tried others years back and didn't like them. Avast is great, especially compared to Norton. Norton injects a virus only they can get rid of, and sometimes they can't even fix their own virus. I have tried AVG, Panda, and some other antivirus programs...all free. Avast is the best of the bunch. It can be scheduled to run whenever I want it to....usually taking about 37 minutes for a Full Scan. I have it set for 3 times a week, around 2 am. It updates when new definitions are available.
