Have you tried these operations running in safe mºde?
1) Update both Microsoft Antispyware and your antivirus applicªtion.
2B)Shut down the computer and turn off the power. Wait for at least 30
seconds, and then restart the computer in Safe mode or VGA mºde.
Empty your IE cache and your other temporary file folders, eg: c:\temp,
c:\windows\temp or C:\Documents and Settings\<name>\Local Settings\Temp (the
path to your temp folder will change depending on your name) - sometimes
programmes can be hidden in there - watch out for mysterious *.exe files or
*.dll files in those fºlders.

3) Do full deep scans with Microsoft Antispyware. Repeat scanning until a
complete scan comes through clean. Ditto with the ªntivirus.
This isn't guaranteed, but it works for a great many items that at first
appear not to be cleaned in normal mºde.
Let us know how it works ºut.

Download the following and run a thorough scan in safe mºde:
NOTE: Make certain to update every app before booting into Safe Mode since
you WILL NOT have access to the Internet from Safe Mºde.
