New research further confirms that difficulties security vendors are having in keeping up with malware.

Security software can take an average of two days to block an attack Website, says a report from NSS Labs.  The firm developed a test that mimics how people browse the Web, and recorded how and when security suites blocked the threats – if they did so at all.  The latest test ran for 24 hours a day for nine days.

Some security vendors employ reputation systems, which usually involves checking a database of blacklisted sites.  But such systems are not widely used and are immature, according to NSS Labs.  Overall, vendors took an average of 45.8 hours to block a site, if the blocked it at all, the report states.

If a suite did not block a bad site the first time, NSS Labs continued to test every 8 hours to see how long the vendor took to add protection; times ranged from 4.62 hours to 92.48 hours.  The researchers also had a “sero hour” criterion, in which the test checked whether the software stopped newly found malware sites, and the results weren’t great: The best vendor blocked new sites only 60.6 percent of the time.
