What you want to do is delete that hack right away.
Here are a few options:
Find a system restore point and restore your computer.
Re - format your computer or get new windows.
Reset your WHOLE computer.
Get an antivirus and then take out the viruses, they won't be all gone unless you have a real decent AV.
Edit that hack if you know how to.
Those are some of the options I suggested people on CrossFire that used this hack. Hopefully, these help you get rid of your viruses from this hack.
