Bad link added to posts randomly

[DejaBlue]

Since yesterday I've been having a really weird link added to the bottom or my posts for some reason.

It's a lot of numbers and percent signs and I'm pretty sure it will appear below this post so you can see it.

WHAT is the deal here and how do I make it stop?

Nope, I don't see a thing.

I saw the thread and tried to clean it up. You may have visited a site (not CD) that put some malware on your computer. It may try to attach some advertising or a link to future posts. Run your virus and malware scanning programs to see if that helps.

You must have caught a bug surfing the net, it happens to the best of us.
I suggest you try something like Malwarebytes anti malware or Spybot Serach and destroy (or both!) to scan your computer for any malware there might be, both are free and work great.
