is there a way for clamwin to filter out the aac files that i have on my computer because these files slow down the scan of the computer and there are just too many of them. i could not find the file extentsions for them to put in a filter. does anyone know how to avoid scaning these files?

are they extension-less? Maybe they are in a specific folder, then exclude that folder:
<c:\\folder\\.*>regular expression will exclude c:\folder and all subfolders
