Google Chrome has been showing me a malware warning page today as I try to visit normally trusted and benign sites. I got this one just now as I tried to got to Planet RDF.

Clearspring claims it’s a technical problem, although they admit they were using a service that was compromised with files redirecting users to a certain malware domain. I’m a bit fuzzy on what clearspring does and where they are being used on the Planet RDF site. I don’t see it in the page source, for example.

update: Maybe the problem stems from flash cookies in blog content being syndicated by Planet RDF that have flash objects mediated by clearspring.
