Well fist which is the version of your windows? possible your infected, first download malwarebytes antimalware and superantisptware free editions, then if you can reboot to safe mode then first scan with superantispyware then delete infections and do the same with malwarebytes antimalware.

if you are on vista then create a recovery disk
1) go here and downloed your version:

2)Burn it to CD, or DVD
