Sigh. I guess rogue is another word that joins the "Overused to the point of meaninglessness thanks to its wildfire dash through the Internet" list (one I don't feel like making). Btw, I sort of like the word malware (if it means what I think it does).
Also scareware, rogue security software, smitfraud.
"Malware...designed specifically to damage or disrupt your computer system. In this case, not only is the software going to disrupt your system, it's going to try and trick you into making an unsecure credit card purchase." --Webopedia
