Hi Voltaire,
I recommend this malware removal guide from Major Geeks.

Yeah, it takes hours but in my experience usually gets rid of them. It is essential to follow all steps in the documented procedures.
If necessary, Major Geeks also offer a free service to review the associated logs and make further recommendations. Yeah each response takes their volunteers a few days to muster.
