These stupid things that says Messenger Service keep popping up. They're made to look like it's a window from windows but it doesn't quite match. It pops up and says message from SYSTEM to WINDOWS about errors with the coputer. THen it tells me to go to some site to fix it. Then it has a OK button. My three spyware and adware blockers (Spybot Search and Destroy, Spyblaster, and yahoo toolbar) won't block the problem either. How do I get rid of this annoyance?
