Antivirus for Linux

There are very little virus that have targeted Linux based operating systems in the past. There for the requirement of a Virus Guard isn't felt badly.

But there are Open Source virus guards that are available for download. CLAMTK is one such virus guard and is available for download from http://clamtk.sourceforge.net.

I have heard that there is no necessarily to have a virus guard if you are on Linux.There for just enjoy your time with Linux. You are much safe with Open Source than with Bill.
