Microsoft is raping my computer up the ass. It automatically downloaded something called Vista Guardian and says there are 29 trojans in my computer. It refuses to load the desktop, run Mozilla Firefox, and show the start menu unless I activate it. Which costs money. And I don't even want it since I have AVG to do this for me.

Somebody, anybody, HELP!!!

Edit: Alright, it turns out Vista Guardian is total malware and I'll have to permanently remove it. I'm trying to remove it from my Registry, but the code refuses to be deleted for some reason. If there's anybody that knows how to remove malware properly, please contact me. You'd be a big help.
