You need special software like av antivirus or something to root out a root kit exploit. You may have to download from another computer and start your computer in safe mode and load the program and run it then. You will probably have to do most of the viral fighting in safe mode. I had to wipe my hard drive and reload windows. If you have a back up that was made prior to the infection you can do a restore.
Click start%26gt;click run type in msconfig and then press enter. Goto the start up tab and uncheck everything except your anti virus,click ok and reboot.

1. Download and run firefox to protect your from future spyware attacks and pop ups which are coming in through Internet Explorer IE!! (Trojan downloaders, win32 ).
