funny UST scandal virus

last 2 weeks ago, my system was infected with a virus named funny UST scandal. i dont know how to fix it coz my McAFee antivirus was not able to do it. its characteristics is to close every program that thought might be dangerous to itself. if i run my computer into safeboot, virus is closing it before i get into safeboot. And when i open task manger, the virus put it to system tray. And i noticed processes that running killer.exe, smss.exe, lsass.exe. The virus also is running the same name, with system process, lsass.exe.
Until now my PC is still infected with the unfunny "Funny UST scandal virus". Hope to fix it as soon as possible.
