This came out in late August, but is still very relevant – have a look at Symantec’s List of the 100 Dirtiest Web Sites of Summer 2009.

While over half of the sites are porn, that isn’t what Symantec means by “dirty” – they are specifically referring to sites with malware attached, where just viewing the site can unleash problems on computers.

Symantec says it like this:

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.
