My Dad's Vista Home Premium laptop is now infected with this virus and I don't know how to tell him to fix it. He has Avira, SuperAnti spyware, SpywareBlaster, SS&D, AdAware. Is there anything I can do to help him get rid of that nasty virus? He can't get online at all. Is his information on his PC safe??

I need the safest, easiest, step by step directions, I C a lot when I google but I'd like a most trusted source if you all can recommend one please.

Thanks

Edit: Dad says Avira free detected the virus but it was after he hit "remove" that he got infected with it :(
