According to Reuters, the FTC has asked 3000 Internet Service Providers (ISP’s) to block customers determined to be infected by Worms and Viruses. Since it is estimated that over 50% of SPAM is sent from infected computers unbeknownst to their owners, blocking them would significantly reduce SPAM and may also reduce the spread of such Viruses. Apparently 25 other countries will be taking part in the campaign so this might become something of a world wide issue before long. The benefits of such a campaign are not limited to a reduction in SPAM and Virus emails, it may also help to curb zombie armies of infected computers being used by unsavoury types to extort money from online retailers and gambling sites.
