Linux Antivirus

Quote of the Day:

With Linux you actually get to use your system’s resources for doing what you want to do, not for running a whole bunch of utilities designed to protect it. Linux is protected by its design, not by third party products.

Was helping to look for Linux antivirus and came across the above comment. Come to think of it, it sounds dumb to run Windows plus a suite of programs on top just to protect Windows. Then again if Windows tries to build more security into its OS will it become another anti-competition saga?
