Rough Type: Nicholas Carr's Blog: Google uncovers a million malware sites

Yikes... 

Google's program to identify internet sites that distribute computer viruses and other "malware" has so far uncovered one million web pages that are infecting the computers of unsuspecting surfers, report Panayiotis Mavrommatis and Niels Provos of the search company's Anti-Malware Team. Most of the sites engaging in what the researchers term "drive-by downloads" are ordinary sites whose owners "are often unaware that their web servers have been compromised."

Based on an analysis of a sample of sites, the Google researchers estimate that one in every thousand websites may be "malicious."
