An odd issue. It launches in background when I start my PC. I don't see it, but when I ctrl-alt-del and go to task manager, there it is. So I select it and End Process. And 2 seconds later, it relaunches in background and shows back up in task manager.

Spybot finds nothing.
MicroSoft Security Essentials finds nothing.
Sophos finds nothing.

I question all of them, because this doesn't seem normal to me.
