Thanks for your reply.
I noticed that the files not scannned appeared after Avast updated def file, and files not scanned had a broken file path error, C: Program Files.... so I uninstalled Avast with the uninstall tool in Safe Mode and reinstalled Avast. Did this twice and used CCleaner to make sure all was wiped off.
Now, the fresh install of Avast WILL NOT UPDATE!!!. Stuck on initializing -- again!. Went to Control Panel and tried repair. Rebooting shows today's def file instead of yesterday, but still hung on initializing.
Have no idea what is going on... never even got to the files not scanned issue.
What gives?
