How the heck did you manage to download and install it?
I tried googling it and see what their website looks like and it's spammed with removal instructions.
Format and reinstall Windows is the best way and if you are looking for a free antivirus, get Microsoft Security Essentials from
http://www.microsoft.com/Security_Essentials/
It's legit, free and I have no problem with it whatsoever. In my own opinion, it's better than NOD32, most people with good computer knowledge tend to go by NOD32. However, now that MSE is out, I am not so sure!
