Eric Davis, Head of Google’s Anti-Malvertising wants Internet Service Providers (ISPs) to take a more proactive approach to dealing with malware-infested computers on their networks. During a keynote presentation at the Virus Bulletin conference, he said “The ISPs are in the best position to detected infected machines. They’re in the best place to do something about malware. They already’ve monitoring systems that could be used to identify signs of malware and botnet activity. If they see abnormally high e-mail activity, that’s most likely spam from a botnet. However, because ISPs have no monetary incentive to notify and help disinfect machines, the botnets live and thrive within ISP networks. Detection is expensive and tech support is expensive so they don’t do anything about it,” (emphasis added) Davis said.
