Ok I have been using Hitman Pro for a while now and I have been pretty impressed.
Hitman Pro is the first tool I use when working on an infected machine, In a matter of minutes Hitman Pro will find and remove the worst of the infections in the machine and if it encounters an infected file that can not be cleaned it will prompt you to insert your operating system disc and then it will remove the infected file and replace it with a good one from your disc very impressive!
I still recommend running scans with MalwareBytes Antimalware and SuperAntiSpyware afterwards to find any leftovers as Hitman's main job seems to be to target the worst stuff and knock it dead fast which is great because it clears the way for the other programs that would have had a hard time finding and removing this stuff do yourself a favor and check out Hitman Pro.
