Hello, sounds like you have a virus or spyware infection to me. Download/Save ComboFix and run it.
(IMPORTANT) Click OK to continue on those popup messages from combofix, DO NOT disable the anti-virus, just click OK to go on and you might have 3 different OK boxes to pop up, and if it ask to download the recovery console just click no.
Try to run COMBOFIX and it will take about 5 minutes to complete tops. The Microsoft Level 2 Techs use this and nothing gets past it. This is a FREE scan and it does not install anything on your computer, it runs from the command prompt!

1) Save it to your desktop
2) Run It
When it is done, you will get a notepad with the report. If anything was deleted it will show you at the top like this....

Here is you a guide just in case you want to see what happens.

After that, close the notepad, restart your computer, and everything should be back to normal.
BEST OF LUCK! GOD BLESS!
