I currently have a Windows 7 home built Desktop. Recently I noticed every oh so many minutes I would get the audio for a commercial from my computer. This audio is not associated with any program I'm running as I have restarted my computer and left it without opening anything to see if it would play and it has. I read the post before mine about the gateway computer and it sounds like the same issue. Instead of just following those instructions I thought it would be better to follow my own set of instructions in case it was a different infection. Thank you for any help you can provide.
