I’ve right click on the icon in the systray and chosen “start avas! antivirus”
Then “folder selection” ; when the explorer window is opened, I’ve selected windows ( by checking the box ).

Type of scan : standard ; and scan archives file checked.

At the end of the scan, the result is a great number of files not scanned due to error ( but what kind of error, I don’t know ).

I use Windows XP Home Edition SP1 ( french version ) with NTFS disk.

I hope it can helps.

Sincerely.
