I completed a scan with Avast home edition and go the log message: C:\System Volume Information … 1ipg, Unable to scan: RAR Archive Corrupted. Can anyone help me understand what this means?
It means that during the scanning of C:\System Volume Information folder (i.e. the Windows “System Restore” storage), avast! found a file which seems to be an RAR archive. So, avast! tried to scan the content of the archive (= unpack it), but it failed because the archive is probably corrupted/incomplete.
It’s really nothing you should be worried about… it doesn’t mean that a virus was found, avast! is just telling you that it wasn’t able to scan the content of this particular file.
