Windows – Spam pop-up in every browser

browsermalwarespam-preventionwindows 7

When I'm browsing on the web—regardless of the browser—once in a while there is a pop-up in the bottom left corner.

popup window

I tried scanning the computer with Ad-Aware & malwarebyte.org but that didn't solve the problem.

When I right click on that Spam block, sometimes i get a menu with copyright information. The copyright says it belongs to "DSNR Media Group".

Because the "popup" is XP themed and your version of Windows is using the Aero theme it is obviously not an actual popup generated by the browser or a program, but a website's "trick" popup. As @jdh said, it is most likely a javascript or similar active content "feature". If you want to get rid of it, look into ad blockers such as AdBlock Plus or NoScript.
