Thanks for all the answers.
I modified "Settings -> Report file" to notify also about OK files, and now I see that some files indeed are scanned. I was also able to select "Scan archive files" and "Thorough Scan" from the popup-area before scan. Good.
But not great. If you look at the list of files skipped, you'll see it includes C:\ATI\SUPPORT\wxp-w2k-catalyst-8-062-040929a-018115C\BIN\atiicdxx
.ini and C:\ATI\SUPPORT\wxp-w2k-catalyst-8-062-040929a-018115C\BIN\OEMInstall
.bmp. Does Avast consider these to be "archive files" as well? But even if it does, I think they should now be scanned with my new settings. These files are NOT (Windows XP) encrypted. (Can Avast handle those?)
A side-note: In the "settings" I've set up the log-file size to 4096 KB, but after deleting it and doing a full scan, the log-flie size was 131 MB!
Thanks again
