Sound distortion

I have CIS installed and Avira AV. I’ve noticed that every time I open a new browser window either IE or Firefox, sounds is distorted. It used to happen with AVG when it run its scan. And it stopped for some time until it reappeared for the past few days – there’s been a CIS update in the meantime.

Has it happened to anyone else?

Thanks.

Are you running the latest drivers for your audio device? Do you have the resident shields of Antivir and CIS running at the same time? If so try disabling one of them.
