I don't know if it's your fault because they were dumb enough to just have a mcAfee trial running on the PC.
Here's how you could have avoided your problem:
Now as far as downloading stuff, you are out of luck....you won't clean up the problem with what you have on your PC.
Tap f8 on bootup and choose safe mode with networking. Open IE and download these progs:
1- rkill.exe (will kill the rogue process)
2- tdss killer (will remove the unwanted rootkit if it's there)
Run those 2 and clean out all they find, then run your malwarebytes in full scan mode.
That should remove the problem, then reboot and see if it is solved.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
