I tried to go read this article about bikes bikes bikes on the Portland Tribune site and instead received this threatening notice:
"Of the 178 pages we tested on the site over the past 90 days, 114 pages resulted in malicious software being downloaded and installed without user consent. The last time Google visited this site was on 2010-09-16, and the last time suspicious content was found on this site was on 2010-09-16."
Ack! The trouble you get in for trying to read a damn paper.
