Beginning around November 9, 2009 , 30-40 MB temporary files with names av*.tmp began to be left in my C:\Windows\Temp directory on a daily basis. I think that the this may be associated with the upgrade to Internet Security Suite 9.1.008 in early November. (Earlier versions and the current version seem to leave 1 or 2 1 KB ZLT*.tmp files each day which aren't a problem space-wise.) Updating may have slowed too. If this is what is happening, do you have any suggestions to get Internet Security Suite to clean up its temp files? I'm running Windows XP.
