I would scan your machine with something like Malwarebytes, spybot search and destroy etc... Then go in and delete your Temp Files folder (usually where these freakin' things set themselves).
Once you have done that, I would install AVG or Avast and set it up to do a daily full system scan and a convenient time for you. Those two work great, I prefer and run Avast.
I agree that these jokers that put this shiz out there need to be castrated. I have come to the conclusion that the same companies that create programs to fix em have a separate department in their basements full of dudes writing up these worms and trojans that break our systems in the first place.
