avast is unable to scan the following 4 files because “the cab archive is corrupted”
C:\Documents and settings\user\Local Settings\Temp\IXP00.TMP\netfx1.cab\FL_sorttbls_nlp______.3643236F_FC70_11D3_A536_0090278A1BB8

C:\Documents and settings\user\Local Settings\Temporary Internet files\Content.IE5\FP2ZSX82\swflash[1].cab\Flash9.ocx

i have searched the forum and it seems that there is no particular reason to worry about them.
My question is: Is there a way to find out if they are really corrupted or that they work fine and just avast cant scan them?

Yeah. Don’t worry.

Do you have a zip/cab tool, like WinZip, WinRar, etc.?
If so, you can open the files and ‘test’ them. Maybe it was just an avast unpacker problem.
