ClamWin. It's not an active scanner, just when you tell it to. It's also pretty much a consumer-targeted port of UNIX/BSD/Linux's ClamAV, which is an enterprise-grade virus scanner. Usually used on the main mail servers for large companies.
Free Antivirus for Windows - Open source GPL virus scanner
Oh, and since it's open source, it's free. I haven't used it because I have used 90% linux for several years now, but ClamAV is rock solid so this should be too.
I know of one, called OSX. Lol
I guess people just assume that there's nothing worth stealing on a Mac.
:lmao:
Since OSX is BSD-based (unix-clone), it takes a completely different design direction from Windows. It's not only much harder to successfully install malware onto a computer running OSX, most consumers still run Windows anyway. A virus is way more successful if it can target and infect more computers. Apple's status as a minority in the PC world has saved it some. I imagine if it gains a significant market share, people would start to target it.
