I'm looking on our forums and I see ads when I click on the website or either some underlined words. I don't know what they are about, but looks they have been added in each vBulletin forum, at least those I've seen. I cleared all caches from my website, probably made a full clean up of the Chrome, but still nothing. It's this only me or everyone?...

If it is only me, can you please give me a method of how to clean this up?
