....[AsPack] not scaned ?

Because the files that end with [AsPack] :
C:\Windows\OPTIONS\CABS\PWS\FP30EXT.CAB\iwrds.dll[AsPack]
C:\Programmi\DiretcX9\BDA.cab\mpe.sys[AsPack],

cannot be scaned and the result is “unable to scan: archive is corrupted.”
Thank you.

This was a bug in the update Version 412. Update to the latest version of Avast and it should fix it:)
