Did you pay anything/buy anything from these people? If so contact your credit card company right away.
The best thing to do is not easy. I would back up all your data with Windows Easy Transfer to DVDs or a separate harddrive (Windows easy transfer is part of W7, simply type Easy in the start search bar). I would also make a back-up of your drivers to another DVD using something like freeware
Double Driver (Windows 7 has most drivers and will usually download the rest on reboot but it's nice to have them just in case). Then I would completely reinstall Windows, install your AV software and malwarebytes, then restore the WET data, Run a full system scan on all your data, and then reinstall all your other programs.
For me, all the registry tweaks and programs I install this would take at least a day working on and off; longer if I get frustrated and throw my keyboard out the windows and have to go buy a new one so I know this is not an easy thing to suggest but it is the only way I would feel safe after such an event. The truth is, even restoring your data could risk reinfection, that is why I recommend a total scan before you reference any of it after your fresh install.

If you have a complete system back-up taken BEFORE all this junk started happening then that could save you a lot of time because you can simply back up your data and then do a complete system restore. We do recommend these complete system back-ups, but unfortunately most people are not aware of their need or benefit until something like a virus or a hard drive failure causes a catastrophic loss.
BTW the 10 character limit is just a thing for posts, they can be 10 periods or you can say "here is the error report" and you easily have the 10 characters.
Also this is a new problem so I moved it to its' own thread.
