THE FOLLOWING ARE WINDOWS ONLY!
In my last post, I linked you to some good on-demand anti-malware scanners.
The following is a good on-demand AV scanner:

A great real-time AV is Avast Free Edition:

If you ever use NPE or HitMan Pro, always create a restore point. That way, if you delete something that they find that you should not have, you can always utilize your restore point. As long as System Restore is turned on, your system will create checkpoints for you to restore your former settings in the event that a false positive is deleted and causes some kind of system instability or malfunction that you need to correct.
Note: Avast and MBAM have quarantines. You can simply restore your system back to the pre-deletion state without utilizing Microsoft's System Restore.
