Hi Folks, I have this problem. It took me 2 hours stuck with my computer ( my spouse was a bit *&^%%)
I sent a ticket to Avast, quick, got the reply same day. Posted below for sharing.
Hello,
Thank you for contacting ALWIL Software company with your concerns.
Some files are permanently locked by operating system, some files are
in password-protected archives and so on. These files can´t be
scanned. It´s normal and you don´t need to worry about this.
Error is trying to handle a file and temporary avast files.
Files that can't be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.
If you want you can send us the log file.
Follow all described steps below:
1. create a custom scan
2. use the option to generate avast! report file
3. tick all available Reported items options
4. run virus scan
5. send us created report file, located under C:\Documents and Settings\All Users\Application Data\Alwil Software\Avast5\report
If you need further assistance, don't hesitate to contact me again.
Best regards,
Miroslav Jenšík
