Repeated server login requests

I'm getting this a lot this morning. 

Anyone else?

What is that site? That is not associated with us. May I ask how you're getting this prompt? To clarify, is this a separate site, or do you think this is a virus on our site?

[Bonecracker]

I think it may be a virus. It only happens when I go to upload an image, and then if I quickly command period it, and back to previous page I can get the image to upload and publish.

And It doesn't happen at any other site.

I've looked into the issue, nutit is/was a popular website. I hadn't heard of it until now. Have you ever visited this site before? Needless to say, our server isn't associated with them.

I should also say that we have virus scanning software, and it hasn't gone off either.

One of those weird things that hasn't happened since either!
