On Antivirus Failures (?)

Wow, is this news or what? I didn't have that much respect for the AV efficiency, but I didn't think that it has an 80% miss rate: "'At the point we see it as a CERT, which is very early on -- the most popular brands of antivirus on the market … have an 80 percent miss rate. "

How does one explain this? I suspect those guys took all the spyware and badware universe and just checked how many of those "baddies" were caught by the vanilla anti-virus folks...

In general, this drives the final (?) nail in the coffin of "malware for everybody" and illuminates the bright future of "malware for its victim."
