I got a window for McAfee & Network associates suggesting that I do a scan.
Firstly, I think that the outdated virus files are NOT Avast files but McAfee definitions. V4245 does not sound like an Avast db number. McAfee is a subscription service, and if your subscription ran out, the program will not allow updates.
Secondly, more than likely, you are running out of system resources and that is why the defrag stops.
Try shutting down all programs with Ctl/Alt/ and Del. except Systray and Explorer. Then try Defrag again. This should do the trick.
Thirdly, let's try a manual update of Avast to be sure you are up to date. You ARE running the latest build of the program so that's a plus. Right click on the "A" ball in the tray and select Updates. Click on Database update.
Either Avast will tell you that you are up to date, or it will update the db.
NOTE: AVAST DOES NOT LIKE OTHER AV'S RUNNING ON THE SAME SYSTEM! If you are trying to run Avast and McAfee....I would not. Personally, I would try to run Avast alone and uninstall McAfee (also since the db is 5 months old).
Good Luck
