krufruf on "Website with possible Malware"

Hi all. I'm having a hard time getting rid of some malware (or looks like malware) on my site. It's just one line of malware that shows up on each page within my site. I have several security plugins installed, but nothing has fixed it. I also ran the https://sitecheck.sucuri.net scan and it comes back and says no malware found. My plugins are: Block Bad Queries, Anit Malware and Brute Force, Akismet, Sucuri Security and WP Antivirus.

Here's a link to my site (every page looks to have this one line of malware text): http://www.ofcia.org/about-us-2/

If anyone could help, I would appreciate it! We are a non-profit organization, so funds are not available to join a monthly security scanning site/plugin.

Thanks in advance!
