my computer has decided within the last few weeks to rebel against me and misbehave: i get multitudes of pop-ups, literally 10-15+ within a few minutes, as well as several different "antivirus" programs that continually pop up and try to download themselves. currently there is one with a "license agreement" screen that, upon showing up, cannot be closed. usually after a while of this, my start bar disappears and i have to reboot before it will come back. i'm using windows XP, and have mcafee security software which at least 3 times a day says it has detected a trojan or bad program and that it has been removed. also, when i reboot my computer, my desktop has started coming up blank, and a warning message says that "x is a bad image please check it against your installation diskette". so basically, i'm on self-destruct here and could use some help! thanks!
