MainBoardSearch malware on clients mac

[MoonageDaydream 0]

I installed Cyber Security Pro on a clients iMac and it detected a malware infection - MainBoardSearch - I have manually removed as much of it as I can find and yet ESET is still cleaning files generated by the malware.  All the manual remove software appears to be for Windows and not mac, I really need to fully remove this malware and ESET just isn't doing it.  Any ideas?  I've been using ESET for many years but it seems to struggle with this one.
