Did you go into safe mode and try running Malwarebytes from there?
Try running Smitfraudfix and Combofix while in safe mode with networking. If they both run and find virii, run Malwatebytes after updating it first.http://www.bleepingcomputer.com/download/combofix/http://siri.geekstogo.com/SmitfraudFix.php
Then while still in safe mode install Ccleaner and run the registery section of the program to clean out the registry after running everything else.
For good measure boot to and run Kaspersky like LatiosXT suggested.
