Welcome to BleepingComputer.
Rootkits are bad news. They are designed to be a stealthy as possible and nearly impossible to remove. I recommend following our malware removal post
and then posting a HJT log in the HJT forum. The HJT team are very good at removing the bad stuff. One note, just be patient. They are very busy working logs and are all volunteers.
Good luck getting rid of the rootkit. If you have any questions - just ask.
