My site http://www.ofcia.org is showing what appears to be spam on every page excedt the main page. There's a fictitious link that leads to a Facebook like box. Can anyone direct me as to how to get rid of it? I'm using several security plugins to no avail. They scan, but come back not identifying any spam.
Plugins: Anti-malware and Brute Force Security, Sucuri Security , Block Bad Queries, WP Antivirus Site Protection
(free versions - not pro)
Thank you in advance.
