I recently became infected with the Conduit search system and some other malware. I have been able to remove most of the malware, but now sounds play out of my headphones when no programs are open. They seem to be radio commericals. The sounds come and go, sometimes sound broken or choppy, and sometimes two or more sounds play over each other. They stop when I disconnect my internet.
I have run some internet searches but cannot find a solution. One site said that Kaspersky trsskiller solved the problem. So far I have run Kaspersky PURE 3.0, HitmanPro, and Malwarebytes. I have removed a lot of malware and trojans, but now the scans are coming back clean and the problem persists.
This thread describes my problem, and seemed to result in a solution:
...however, I'm not entirely sure what the person did.
