Okay, it appears to be a Chrome thing. Sorry folks.
To answer my own questions:
1. A third party had installed something called "Yontoo" as one of my Chrome extensions. It, or something similar, is apparently also known as "Fast Save."
2. It has nothing to do with the forums.
3. Deleting the extension is easy as pie. Customize -> Tools -> Extensions -> Delete

Except for the fact that you answering yourself left this in 'question' mode.
Silly forums.
