magpienja, mixture makes a fairly valid point. If you don't know how to ferret around in the registry and make changes safely, it might be beyond your ability to deal with this.
However, to edit the registry, click "start">"run" and type regedit.exe then click OK or push enter.
The registry editor will open in a Windows Explorer type window. (and it works like windows explorer, too.)
Navigate to and find the keys suggested above, then delete them. Be sure you are in the correct part of the registry. (Match the full path to the key concerned.)
One of the problems is that this type of infection is changing constantly, so the filenames, registry settings and paths used by a new variant are often different to the example reported (which was found on a simple Google search.)
What is your OS, your firewall, and the type of Antivirus used?
Another way of cleaning a computer is to post a HijackThis log at a forum that specializes in fixing this sort of thing. Majorgeeks, Mybleeping computer, etc. Depending on the forum and the type of help offered, there would likely be quite a lot of tools you'd need to download and run, and scan reports to post. For a routine cleanup with no particularly difficult or tenacious malwares, it could typically take one to four days.
