"MOOING" SOUND...IS IT A VIRUS?

For the last month or so, I have been getting a loud, "mooing" sound while I'm on the internet. The sound occurs once an hour or so. I've run Norton Anti-Virus, as well as another anti-virus program, but the problem persists. There is no pattern. The sound is not connected to a specific website. It occurs while I'm on various websites.

PatriotLady,

Welcome to the forum.

I am not sure if it is virus related or not and I know you have already run a virus but it would never hurt to follow the below link, have a good read thru it, follow all steps, and post the requested logs so that a specialist can have a look at them.
