Audio /adware comming out of the computer

I am working on a  Windows 7 computer in which advertising audio is constantly coming out of the computer. I tried scanning with Malwarebytes  and found no 0 bad items to clean. I also don't see any programs installed under Programs . The user said she was just browsing the internet and this happened.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Does it happen when the browsers are not used?

You can use Process monitor and filter path to  ends with *.mp3 or *.wav or any other kind of music file extension to see which process is using audio.

Run the following programs in sequence and clean the reported items and post the logs here:



Maybe add/remove programs?
You can also run HiJackThis to see what is currently running. Often this will help you find the culprit. The above mention of ADWCleaner, I completely agree with - I find it to be the number one tool I use in almost every situation of infection. You can also try Norton Power Eraser, and clean everything up with CCleaner.

(anything that is running out of appdata typically points to bad news, and there are resources to help analyse the findings of the tool to be found all over google)

Norton Power Eraser:

This will clean up temp folders, and you can also use it to remove programs and clean up your registry

Make sure to check for strange items in ProgramData and task scheduler as well

Hopefully you fix your issue!
