yady, Two Words...well, three. Rkill and Malwarebytes
Free downloads on bleeping computer. Those should rid the viruses for you. You may have to download them on another computer and transfer with a USB. You may also have to rename them so the viruses don't recognize them, so make sure they are not .exe files when transfered.
Restart the computer, keep hitting F8 and then when your screen asks, do Windows (or whatever operating system) in safemode with networking. Install the programs, run Rkill, then do a full scan of Malwarebytes. When done, quarantine the viruses, restart the computer, open Malwarebytes again and go to the Quarantine tab, then "delete All files". Restart again and you should be good to go.
