How to remove My Security Engine (Uninstall guide)

Tell your friends:
My Security Engine is a rogue anti-virus program that may cause serious system performance issues on your computer. This fake program is from the same family as CleanUp Antivirus malware. It performs fake system scan and reports false system security threats to make you think that your computer is infected with malicious software (spyware, adware, Trojans and etc.). The scan results are false. My Security Engine creates numerous harmless files upon installation and then flags those files as infected ones. How rude. Finally, it asks to pay for a full version of the program to remove the infections which don't exist. In other words, MySecurityEngine is a scam.

ok....i have used malbyte's malware program....does not show being infected. I have also done this in safe mode. I have check the registry for the appropriate entries...non found. I even deleted and entered a HOSTS file (as was suggested on another site). I do not find any programs that could be removed with the windows remove program options. However, when I try to install PCTOOLS Internet Security, it still shows "My Search Engine" on a list of contradicting programs that need to be removed before installation can occur. What do I need to do next?
