I am concerned because when I use it to do a full scan of my hard drive Avast always ends at the end of its report by listing a long list of files that it was unable to scan. That does not sound safe to me.
So I downloaded A-Squared and it skipped no files and found a couple of virus infected files that Avast had not found. (I checked them out and they were indeed infected).
Question: why does Avast skip certain files (I have nothing entered under exclusion) or is unable to open and scan all files? Seems like that is an unacceptable loophole for a virus to hide in.
Files that can’t be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.
You have said this three times now, but without information there is no kind of investigation anyone cane do. You could always send the samples to avast.
Send the sample to virus@avast.com zipped and password protected with the password in email body, a link to this topic might help and undetected malware in the subject.
Or you can also add the file to the User Files (File, Add) section of the avast chest (if it isn’t already there) where it can do no harm and send it from there. A copy of the file/s will remain in the original location, so you will need to take further action and can remove/rename that.
Send it from the User Files section of the chest (select the file, right click, email to Alwil Software). It will be uploaded (not actually emailed) to avast when the next avast auto (or manual) update is done.
Anderson, for your peace of mind, just disable the reporting of hard and soft errors files into the report options
Like David said, files that cannot be scanned are just that. Other products, like Igor said, do not report them.
