Spam somewhere in code

I didn’t see a recent post addressing this, so sorry if I’ve missed it…

Somehow there is Viagra and Cialis spam somewhere in my site. When I post links on Facebook, it sometimes comes up as the site description. I’ve also seen it as the site description in a google search.

I backed up my database, did a reinstall of WordPress, then restored the old database in my GoDaddy settings. It’s still happening.

Has anyone seen this and, if so, any idea how to find it and remove it? I can’t find the code in any of the editors.

Thanks.
