What is "BIT367.tmp"?

Every time I open Windows XP, AVAST notifies me that the file “BIT367” is malware and places it into the virus chest. The size of the “virus” file is 4125696 and the original folder is C:\Documents and Settings\All Users\Application Data… The virus description is WIN32:Malware-gen.
Please note this file has been placed in quarantine seven times today.
Any help is appreciated,
Fred
