As I reviewed my scan report files, I noticed that Avast doesn’t scan a lot of files for the reason that it “cannot access the file because it is being used by another process.” Is this normal?
I notice also that the scan of many files from “System Volume Information” (I believe that’s my restore file) show “Access is denied” results. Is that normal?
It seems like a lot of files are not being scanned either because they are “being used by another process” or “access is denied.” What can I do to correct this?
Just in case its useful info, I’ve attached the logs of 2 recent Avast scans to this message. The first scan was run under a standard user account; the second under an administrator account.
FYI, I ran the second scan under an administrator account thinking that maybe not having full administrator privileges was the reason why some files could not be accessed; but I guess that wasn’t it. :-\
Are you logged as an admin when the errors occurred?
The files on System Volume Information belongs to the system and not to the admin.

No for the first scan. But yes for the second scan. I am currently running another scan under my Admin account. Will post again with result.
This means that it doesn’t matter if it’s an Admin or a standard user doing the scan, right?
Yes. You need to run a boot time scanning for that.

Ok, I reproduced same the “access is denied”/“being used by another process” results with another Avast scan under my Administrator account.
Do I understand correctly that these “access is denied” and “being used by another process” results are “normal” and I shouldn’t be surprised seeing these results in my Avast report files? I just want to be sure I shouldn’t be worried.
Thanks for your responses.
They’re normal. Thanks to avast of reporting them. Other antivirus just ignore them.
Please, run a boot time scanning.

Great!!! Thank you so much for your help. Will do a boot scan now.
Post back the results.
The report file is created automatically in C:\ProgramData\AVAST Software\Avast\report\aswBoot.txt
Or something like that

Hi Tech,
Thanks again for your help. Thought I would mention that in scouring the interwebs (and this forum) for info, I came across this helpful post:

Is that you posting way back in 2003? If so, you’ve been around quite a while! 
Wow… I was Technical at that time
