LONDON -- ScanSafe, the global leader in managed Web security, today released its latest Global Threat Report on Web filtering, spyware and viruses. Among the report’s key findings, ScanSafe reported that Web viruses decreased 47 percent in September, despite recent high-profile Microsoft vulnerabilities, and that one in every 200 Web pages viewed in the workplace were YouTube pages.

The ScanSafe Global Threat Report is based on real-time analysis of more than five billion Web requests and more than 10 million Web threats processed by the company in September and represents the largest analysis of Web security threats based on real-world traffic.

“We were surprised to see such a drop-off in Web viruses during September,” said Eldar Tuvey, CEO and co-founder, ScanSafe. “With all the recent attention on Microsoft vulnerabilities and zero-day exploits, we thought we’d see an increase. Despite the hype, a mass outbreak did not occur in September. In fact, none of the top-10 Web viruses blocked by ScanSafe during the month were exploits of Microsoft vulnerabilities uncovered in September, including the much publicized VML vulnerability,” Tuvey said. “While these vulnerabilities were exploited, the exploits did not occur in high volume.”
