You got the message that files could not be scanned because it was Avast’s way of doing housekeeping because you are going overboard in doing scans. Most people do a Quick scan weekly and a Full scan once a month; a Boot scan is only required when there is a problem found. If you back off on some of the scanning, you shouldn’t get this message (or shouldn’t get it as much since your logs as now so long).

I’m assuming you have an Hp machine. Here is a link to the message you got re: malware on 7/2 http://www.file.net/process/hpzscr01.exe.html. Where is this file now…in the Virus Chest or did you delete it? If you need assistance in removing it, let us know and we will arrange a malware specialist to assist.

BTW, are you using MBAM Premium (resident) or on-demand? The Premium will provide you better protection.
