The problem with running a System Restore is that it will reinfect the computer if there are actual malware infections in the system restore files.. So, at this time, I would update both of the programs I mentioned earlier, then restart the computer into Safe Mode with Networking". Once there, click on the link below and download the free online scanning tool to your desktop and run it.. It should be able to run an online scan.. Delete anything it finds.
Once you've scanned the computer using the online scan, then update both Malwarebytes and SuperAntispyware while still in Safe Mode with Networking, then run full system scans with them both again.
Hope this helps and let us know how it goes.

You may also wish to consider monitoring your system a bit closer.
I often recommend Secunia PSI as it beats buying a full blown vulnerabilty scanner, and it's fairly friendly to novice users. I use it on all of my home computers that are running Windows Vista, and Windows 7.
Supports 64 bit as well....
