I'm afraid that this something you would need to contact Dr.Web about, as we do not have power to change actions by third-party companies. It's quite strange that this message is appearing though, as Dr.Web's own online-scanner is reporting your site as being clean.
Cheers for the link, I've reported it to them, I also found it very strange, my site is more used for my Mobile Apps as a update checker (JSON) and to show my customers my contact details, I really need to start building it again
