Not sure if this is a wordpress problem, or something else. But here goes.
I manage a wordpress site: "lipmag.com". When I link to my website on facebook, the little "preview" type box on facebook comes up with an ad for a viagra website. When you click the FB link, it goes through to my website. (Screencap: http://i1125.photobucket.com/albums/l588/theotherlex/Screenshot2011-10-10at25441PM.png )
When I look up my website on google, I also get a result for a viagra website. (Screencap: http://i1125.photobucket.com/albums/l588/theotherlex/Screenshot2011-10-10at23538PM.png )
When I link to specific sub-posts on my website (articles), I do not get a link to a viagra site. The link appears normally. (Screencap: http://i1125.photobucket.com/albums/l588/theotherlex/Screenshot2011-10-10at25559PM.png ).
I have run a malware scan using the WP plugin "WP-MalWare", and nothing unusual came up on my wordpress site.
Has anyone else ever experienced this problem?
