I’m a little late to the show with this, but I figured I’d put this out there, too. There is a malware program going around called MAC Defender that disguises itself as Mac antivirus and malware removal software. From what I am reading online, since I have not seen the software myself, just stay away and do not install it. It asks for your credit card information and it not real antivirus software.
Here are some links to other articles about the software:

If you are searching for legitimate Mac antivirus, I suggest you check out either the free Sophos Antivirus for Mac (which I reviewed here and I run it at home) or Norton Antivirus for Mac.
