I would use or recommend ClamAV.

However, <http://www.pcmag.com/article2/0,1895,1850851,00.asp>
placed ClamAV at dead last (detecting only 1 of 6 viruses) of
about eleven MS Windows anti-virus programs tested by AV-Test.org.

Does anyone know about AV-Test.org?  Do they conduct fair tests?
It looks like they get paid by others to perform the tests ...
Are they as independent as their web site declares they are?

Of course, the PC Mag article tested anti-virus programs that run on
MS Windows rather than Linux, but it still bothers me that ClamAV
was ranked lowest out of ten competitors.

The top ranked anti-virus program was BitDefender.  The company
happens to have a freeware BitDefender for Linux:
<http://www.bitdenfender.com/PRODUCT-63-en--BitDefender-Linux-Edition.html>
This is closed source with a free Linux license.  Does anyone have an
opinion of BitDefender, Linux Edition?
