Top 100 Infected Web Sites Identified

During the early times of I.T., viruses are being transferred via disk sharing. Now, viruses are transferred in so many ways – thumbdrives, email, chat, and visiting infected websites. Protecting your PC from these threats is challenge, because security is a process and not just a product.

Which means protecting ones I.T. infrastructure requires the involvement of all. Installing security applications is not enough. Take for example website surfing. In a corporate setup, the question is what websites do you visit during work? Are you aware that visiting unsecured websites can cause your company millions of pesos?

Just recently, Symantec has identified the “Dirtiest Web Sites of Summer 2009,” the 100 sites with the most threats detected by site ratings service Norton Safe Web as of August 2009. These sites represent the “worst of the worst” based on the number of threats detected by Norton Safe Web.

It comes as no surprise that 48 percent of the Dirtiest Web Sites are, well, dirty— sites that feature adult content. However, the remainder of the list runs the gamut of subject matter, including sites dedicated to deer hunting, catering, figure skating, legal services, and buying electronics. Malware is the most common threat represented on the Dirtiest list, followed by security risks and browser exploits.

Simply visiting one of these sites, without downloading or clicking on anything in particular, 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.

What makes these sites so dirty? For starters, the average number of threats per malicious site rated by Norton Safe Web is 23. Compare that with the average number of threats on the Dirtiest Web Sites list—a staggering 18,000 per site. In fact, 40 of the 100 Dirtiest Web Sites have more than 20,000 threats per site. Being dirty is nothing new for 75 percent of sites on the list, which have distributed malware for more than six months.

Some of the sites identified were:,,,, and a lot more.

To find the dirt, Norton Safe Web crawls the Web and performs analysis of millions of Web sites, and benefits from a network of more than 20 million Norton Community Watch members that automatically submit suspicious URLs for analysis in real-time.
