Virus on Mac?

So, I have been using the misses iMac for a while now. I just love her 20″ display. I am really going to get a G5 laptop when it comes out.

I began to look at possible virus scanners. I have been downloading a lot of junk on the Mac recently from [CENSORED] and [CENSORED]. I am not sure if I might have picked up a few things.

Some of the though behind feeling this way is the recent media files are corrupted and some of them open pop-ups when I try run the media files.

I came across Zebra. I have not run it but I will.
