Symantec’s Web site ratings service Norton Safe Web presents the Dirtiest Web Sites of Summer 2009 – the top 100 infected sites based on number of threats detected by Norton Safe Web as of August 2009.

Norton Safe Web analyzes sites using signature-based file scanning, intrusion detection engines, behavioral detection and install/uninstall analysis to identify security risks including phishing sites, malicious downloads, browser exploits and links to unsafe external sites. In other words – dirty stuff you don’t want on your computer!

It comes as no surprise that 48% of the Dirtiest Web Sites are, well, dirty— sites that feature adult content. However, other Dirtiest sites run the gamut of subject matter, including sites dedicated to deer hunting, catering, figure skating, legal services, and buying electronics. Viruses are the most common threat represented on the Dirtiest list, followed by security risks and browser exploits. Simply clicking through to a site with these threats could put you at risk of exposing your computer to infection, and worse, put your identity, personal and financial information into the hands of cybercriminals.
