You might want to post in one of the Microsoft virus newsgroups also. I
would make sure that you are using the very latest definitions for anything
you scan with and also scan in Safe Mode. It could also be that just a
remnant of the program is left over and running a registry clean up program
such as the free RegSeeker could help. I recommend that you select the
option to backup the changes to the registry before cleaning however. ---
