This is similar to the stats published by AusCert a couple of years back where they claimed that AV software failed to detect 80% of new malware:
<http://www.zdnet.com.au/news/security/soa/Eighty-percent-of-new-malware-defeats-antivirus/0,130061744,139263949,00.htm>
Interestingly, AusCert still describe up-to-date anti-virus software as being "essential", per http://www.auscert.org.au/render.html?it=6891
In any case, the above relates to Windows desktops -- we are yet to see a rationale for adding AV support to the Linux kernel.
