Infected Windows PCs Now Source Of 80% Of Spam

twitter writes "The Register is reporting a study by Sandvine.com that blames Microsoft Zombies for 80% of all spam. The study goes on to claim that 90% filtering is not effective given the unprecedented volume and that sophisticated trojans are able to drop spam directly on end user's computers despite current efforts. Just another cost of supporting Microsoft, I suppose."

This is probably a dumb question, but is it not possible for ISPs to virus scan all web traffic? Your "service" should not infect your customers computers. In any other walk of life that would be basic expectation.
