Spam pop-up in every browser

Question

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.

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".

Solution 1

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.

Solution 2

If these popups appear in every browser and random websites which usually don't have these popups, that's crystal clear: you got a malware.

Too bad the software you tried didn't detect it. Report it to the publisher, they'll be happy to eradicate it.

Describe the pop-up in more detail. It sounds unassociated with your browser and is possibly an infection your computer has. Try investigating your computer with the MalwareBytes software. malwarebytes.org

I suggest you give a screenshot. "A popup" is quite vague.

Usually a pop-up within a browswer is from the javascript downloaded from a particular site that is then active. Note which site you are both visiting and just changed from, when the popup occurs. Also make sure your browser has popups disabled.

@JoshDM The scan with malwarebytes.org didn't help, anymore ideas?

Is it the same one everytime? If it is, try blocking that site USACG.org? from opening popups.

Does this occur on every website? If so, it's probably some malware you have installed that is under the radar of the malware detectors. Look in Add & Remove Programs for anything suspicious. Have you installed any trialware/freeware lately?

I am well familiar with the popups in the screen caps you posted. I can tell you with certainty that Adblock+ in Firefox stops them dead. Internet Explorer on the other hand, I've never found a way to eliminate them short of totally disabling java script and Active-X. Good luck

The combination of the 2 adblockers did the job! thank you very much!
