ccSvcHst.exe infected...HELP

Okay so i got some messed up virus and the only way to use my computer is in Safe Mode..
When i boot up everythings fine until my backround turns blue with some crazy message telling me my computers infected and then a virus scan starts from some anti virus program that i did not download and then it tells me i have a bunch of problems that i know i dont have because i just did a full scan yesterday and it says i have to buy the program to get rid of the problms blah blah and i cant open any programs or anything. Any ideas?
