Help Required with Win32:Sirefef-AO, Win64:Sirefef-A and -AO

Hi, I need spoon-fed help with getting my computer cleaned up, Avast has been giving me warnings but full scans and boot scans dont seem to solve the problem.

If anyone has the know-how and the patience then I would really appreciate the help!

Many thanks!
