Sweet. Comcast is starting to disable cable connections of PCs infected with mass-mailing worms. While I’m sure it won’t completely stop spam, many spammers are now using zombified PCs to do their dirty work, and Comcast is known for its huge numbers of clueless users. This will help those of us getting bombarded with all this spam, and hopefully these users will learn that failing to secure their PCs does lead to unwanted consequences. Maybe these consequences will even make them realize that they really are affecting others with their actions (or lack thereof).
