I see you posted in 3 different forums on this. Please pick one and stay with it. It's not fair to the folks here to go off looking for ways to help if other people on other forums are doing the same thing. I understand that you want this fixed but since it's not affecting your ability to do your job, be a bit patient.
(we don't have a twiddling thumbs icon or I'd have used that).
Have you contacted the makers of CyberScrub? As your last post mentioned, this sounds like something that happened when you installed the trial 5.0 version, so they have probably seen it before and can help.
What you can try is uninstall 4.0 again, then install
RegSeeker and use it's "Find in registry" function to locate and delete all instances of CyberScrub in the registry. Shutdown and reboot then reinstall 4.0.
RegSeeker makes backups of anything you delete as long as the box is checked to do so. Makes it very easy to restore if necessary though I can't think of a single reason why it would be in this case.
Edit: If you're hesitant to mess with the registry, install
ERUNT. Let it add an entry to your Start menu during the install process. That will allow ERUNT to backup your registry each time you boot. It only takes a few seconds and has no real impact on boot time. Run ERUNT immediately after installing it to create a full registry backup. The restore can even be run from the Recovery Console if necessary.
