Four files can't be scanned

I ran an update, then I scanned. Four files weren’t able to be scanned:

  1. C\mwsSetup.exe.CommonCodebase.exe
  2. C\Users\mws.Setup.exe.CommonCodebase.exe
  3. C\Users\mwsSetup.exe.CommonCodebase.exe
  4. C\Users\mwsSetup.exe.CommonCodebase.exe

I was able to move the first file to the chest. It said:

The original file name is uv9ywi8s.exe. The original file location is C:\Documents and Settings\ann\AppData\Locations. Category is Infected Files. Virus description is blank. File ID 5.

I can’t move the remaining three files to the chest. When I do so, I always get an error message.

Files that can’t be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.

See http://forum.avast.com/index.php?topic=35347.msg297170#msg297170 this topic for more information on why files can’t be scanned.

The important question is what reason was given for them not being able to be scanned, see the above link for more info.

Thank you for the link. I have no idea what program(s) they are associated with. I went to the chest and scanned uv9ywi8s.exe which was associated with the first file. The following are the results

Since Avast is mentioned, does it have something to do with it? What is CAB archive, and why would it be corrupted?

A dumb question, in Vista Home Premium, where is Documents and Settings? I can’t find it in Windows Explorer.

Firstly there is nothing to worry about for any of these. The avast4 folder is where it unpacks ‘Archive’ files so they can be scanned. It uses a temporary file to do this, like the unp165749946.tmp always beginning with unp and ending in .tmp.

However, after a successful scan the contents of this folder should have been removed, why that hasn’t happened is a mystery. You can safely delete the contents of the avast4 folder.

Corrupted Archive file, this could simply mean that avast is unable to unpack it to scan the contents of the archive and assuming it is because it is corrupt. Even if it were corrupt there is nothing that a user can do to resolve any corruption, short of replacing the file. More so in this case these are in the temporary unpacked files.

Whilst I don’t use Vista, the Docs & settings folder should according to the above listing you posted should be on the C:\ drive, it shouldn’t be a hidden folder, though you could ensure that there are no hidden files or folders in explorer.

Ensure that you have hidden files and folders enabled and disable hide system files in Windows Explorer, Tools, Folder Options (I assume these are the same in Vista), Hidden files and folders, see image.
