TechRepublic and Phising site code.

Today, on november 29, 2007, when reading my newsletters from TechRepublic, I started getting alarms of the site loading code from Doubleclick.net
When I asked for more information, I was informed that the Crawler Toolbar Web Security Guard regards Doubleclick.net as a phising site.
The link to the information is:
http://www.websecurityguard.com/detail.aspx?domain=doubleclick.net&lng=en

What should I do, if anything???
