What is ad.yieldmanager.com and how do I get rid of this prompt?

[Aurora]

Hello, not sure where to put this. Each time I go to a link, this prompt comes
up on the lower part of my screen. I don't click on anything I am not aware of so I cancel it out. But it comes up on every click and it's annoying. I have Windows 7. I browse with IE and my security is AVG. It has been happening for a month or so now. I show these programs have updated since Augu 1st, 2013.

Adobe Flash Player
Adobe Reader
AVG 2013
Microsoft Compatibility Pack for Office System
Mozilla Firefox 23.0.1
Mozilla Maintenance Service
Mozilla Thunderbird 17.0.8
Is this part of an AVG security update? Or did another update began this prompt?

The prompt says 'Do you want to open or save get-user-id-js from ad.yieldmanager.com? Thanks for all your help here!

It won't add here through Photobucket. I tried all four (4) Photobucket choices but the picture never appeared in the box field here.
