Those instructions look like having a good chance of working.
Some more info about this
Here. I'm guessing you might not be too savvy about manual removal of this tricky little beast? The registry would be agood place to start, if you can get to it, and are confident about tinkering there. (It is not for the faint hearted- you can bork your computer quite easily by messing with the wrong reg entry.)
Try
MBAM, a good demand scanner. Download the free version. You may need to rename the installation file when you download it, I'd recommend doing that.
If you can install it, update it straight away and then run a quick scan. At the end, select everything found, and click "remove selected". If it prompts for a reboot to complete removal, do so immediately.
If you can't run this, you may need to look at a manual removal.
