I am not particularly adept at malware-fighting; last time I had a major problem with one, I spent most of a week's worth of spare time hunting down precisely what it was by file name, locating it using an anti-virus scanner (that couldn't remove it, just find it), and then hunting on google for a solution. That particular one required me to root-kit my own PC, reboot into a mode the root kit could open, delete the program, then reboot again, bypass boot-up with the root kit to get to it a second time before it could copy itself as part of the boot process, and finally delete it and its installer out of my registry and my hard drive while the root kit held my computer in a barely-running, access-your-files-with-no-security-against-screwing-up-at-all state.
I then had to reboot it a penultimate time, still bypassing things, to make sure it was gone. Finally, I could reboot it normally.
Oh, and the root kit had to be renamed to something other than its actual file type or the virus would delete the root kit before I could reboot my computer. I forget the precise way I had to go about activating said rootkit to get around that.
Let me tell you: I was leery of using a root kit; what if I was giving control of my computer to somebody else? Fortunately, I did research it carefully and identified a place that had a lot of positive recommendations from well-thought-out posters and was backed up by references from outside sources, and it did work. So my computer was mine again. But holy cow was that a lot of work. x_x
