NetworkWorld: New research from NSS Labs calls into question the ability of security vendors to respond quickly to new threats. On average, it took popular security software two days to begin blocking new malicious Web sites.
"The magnitude of these findings should be noting short of an alarming wake-up call for the security industry," said the report.
The report also ranks vendors based on their performance in the testing. Two products--AVG's Internet Security Business Edition and Panda Security's Internet Security--received a "caution" rating, which means that enterprises using it should review their security.
