In checking things out, the Rendo freebies are also hosted by 3D Sara Creations. I found that the location of the files had been changed by the host site, so users trying to download the files would have received an error message of "Page not found". Any virus problems are unrelated to these files, as the files weren't even available through the Rendo link at the point in time when this claim was made. I've updated the link to the files, so they are again available through Rendo.
