I don't know what happened here. I'd been having problems with avast 7 IS not updating. After reading several threads, I decided to do a clean install. So using Revo Uninstaller, I uninstalled AVAST. After an hour of revo deleting over 700 files, I rebooted.
Avast was still there, running perfectly and it updated without a problem. I've never seen that happen before, but am not complaining. I will, though, watch avast very carefully for a while - just in case.
