I just loaded a copy of SuperAnti Spyware today to replace Malware Bytes. When I run it through I'll let people know what I think.
edit: A quick scan took 10 minutes which is pretty good. It installs quickly, scans quickly, and doesn't bog down your system, which is good. The problem is that it needs to get better at doing its primary job—removing malware and keeping it out of a clean system. Until then, I can't recommend it.
