i downloaded your plugin but it didnt detected any malware from my site http://www.matejmichalik.com/blog but it is there /the red text through a photograph/, can you check it out please?
It looks like that plugin is using an iframe to display a page on facebook.com that is not supported. I would not use that facebook plugin unless you can get support from the developer to fix it.
It's not malware but it does need to be fixed.
