I was playing a game through steam and chatting with a friend on skype when suddenly ads and random music began playing. I notice that other people are having this same issue. The problem service appears in the volume mixer but there is nothing I can do that will remove it and it does not come up in the scans I've done. I am running on Windows 7, and I'm not exactly sure what other information would be helpful in this situation. Let me know what is needed for anyone to help me. Thank you.
