run a DLL as an app. keeps trying to get me to activate. The program says it was an update for my computer. I have Microsoft Security Essentials and do not need another antimalware. How do I get rid of it. It is not aon my control panal under ADD REmove Programs. I found the target and it says rundll32.1 person needs an answerI do too

This sounds suspicious. Please start with the basics and make sure your computer is really clean. MS Security Essentials alone will not do it. http://www.elephantboycomputers.com/page2.html#Removing_MalwareMS-MVP - Elephant Boy Computers - Don't Panic!
