Possible that you have run into the mswsock.dll trojan. For more on this possibility, see:

Download and Install MalwareBytes Anti-Malware, run a full Scan. (try starting Windows in Safe Mode, press F8 while booting)

Download and Run TDSSKiller

Download and Install Microsoft Security Essentials (not an official endorsement, but I personally recommend MSE as an awesome permanent anti-virus)

Double check for all Windows Updates.

If you are still having problems with Malware after that, I would recommend either, or having your computer cleaned by a professional.
