Still infected but at least I know what it is....

Smartservice rootkit is what I am infected with... and from what I know there is no known way to rid yourself of it from within Windows.

I am stressing out over how to fix the problem and would love to reformat but don't have a way to do that at the moment since I don't have a Windows Installation Disk and Activation Key :(

Any help would be great although I am unsure if anyone here can help me as this is not a simple or easy problem.
