3. Click it, it should open with a little box.
4. You'll be redirected to the "Applications Box"
5. Press "Processes" and scroll down.
6. It should come up with something like
this.
7. Now this is the important part.
8. Click
here, if you have one "winlogon.exe" then you're clear.
9. If you have two, don't panic, simply right click on one of them and press "End Process / End Process Tree"
10. If you have one, and your shit has been jacked; you've been RATTED, and that can not be removed unless you get the person who jacked it to somehow delete your logs.
