Before we do anything, please move HiJackThis to a permanent folder. I suggest 'c:\program files\hijackthis\' but any folder other than the Desktop or a temporary folder is fine. This will allow us to use backups to restore entries if necessary

Check the following items in HijackThis.

Close all windows except HijackThis and click Fix checked:

Reboot in Safe Mode* and delete the following: (you may need to show hidden files**)
C:\PROGRA~1\Tons enc settings\active bits okay.exe

*How to Boot into Safe mode: http://service1.symantec.com/SUPPORT/tsgen...001052409420406
**Show hidden files/folders as per the instructions here http://www.tacktech.com/display.cfm?ttid=190

Also, uncheck the boxes for hiding known file extensions and hiding protected operating system files. We want to see it all. When we finish here, it would be a good idea to rehide the protected operating system files but leave the rest to be shown.

Reboot. (not necessary, but recommended)
