Malware removal software for OSX?

Howdy Guys!

Right now I have a custom built PE for Windows. Has all the tools I need in order to repair systems with problems like viruses, driver issues, etc. Well, I kind of want to do the same thing for OSX (not too sure if there is a way to make a PE for OSX, but that's for a different day).

Right now I'm searching for virus removal tools (free of course) for OSX. Windows has a ton of them for instance like VipreRescue, Emsisoft Emergency Kit, Malwarebytes, Dr. Web Cureit!, etc, but does OSX have any type of good free software like those on Windows?

I've tried looking on the web but no such luck and after about half way through the list posted on Major Geeks I gave up because all of them were for Windows so far haha.

So anybody know of any free, reliable, full virus scans for OSX?

Thanks for reading guys!

 

i think the main one being used atm is: http://www.bleepingcomputer.com/virus-removal/remove-mac-shield . keep in mind it's for removal only, not active protection.
