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.
They only list a "sample" of 30 sites, sadly. If I had more time I'd see if the whole 100 was available somewhere, but I guess if you've seen one malware report, you've seen 'em all. Probably better to not give them the (any pub is good) pub, either.
You will be relieved to know that WE currently score a perfectly safe set of zeroes all around (safeweb.norton.com) - as you would expect!
If it helps, here the Microsoft Terra Server result. Having not seen the building and based on the Google Maps pinpoint, I'd guess it's the box left of center on the third block southwest of the waterway. (EDIT: Which means I agree with Frosty.)
