Our read Tom sent us a note about a site called "404dnserror/dot/com" (DO NOT VISIT).
A user of his was infected with some spyware/adware. It kept redirecting them to the '404dnserror' page. The page looks like a generic server error, but also advertises an anti-spyware tool in the form of an ActiveX like installer toolbar at the top of the page. To save you the risk of exposing yourself to the site, I included a screen shot below (click on the image to see the full page).
Its probably save to block/montor access to this domain.
