Your os is infected with some kind of malware.
Try this first:
After Malwarebytes' Anti-Malware is installed and *updated*, it is
suggested scanning the operating system in Safe Mode.
How do you boot to Safe Mode?
By pressing/tabbing F8 (or F5 on some keyboards) during re-boot.
A description of the Safe Mode Boot options in Windows XP
http://support.microsoft.com/default.aspx?scid=315222
Start your computer in safe mode (Vista)

Alternatively:
click onto Start==>Run, type "msconfig" (without quotation marks), click
OK. Then click onto BOOT.INI tab and 'check' /SAFEBOOT then OK and click
Restart. To go back to Normal Mode, you must access the System
Configuration utility again and click the General tab then click/check the
radio button 'Normal Startup'- load all device drivers and services'.

There's no updating involved since the scanning engine is updated several
times a day and you simply download the updated scanner whenever you want
to do a scan. Uninstall after use. To uninstall/move this program "enable
self-defense' must be unchecked!
