Windows 7-64 bit seems infected

Hello!

Downloaded and installed small programm from torrent site, and was immedately punished. Tons of ads and shaking screen (kind of screensaver), pop-up windows each 10 seconds etc. Run Malware Malbytes and got 150 or so suspicious trojans/worms etc. Thank to MM cleaning now my PC seems stable, but my guts telling me that something nasty still inside of computer.

When I run Windows Task Manager (Ctrl-Alt-Del) in "Services" Tab I can see too many unfamiliar processes, and computer seems acting laggish sometimes, especially browsers also started to act slower.

Please, help me to cure my poor machine!
