I'm trying to listen to youtube, and avast starts scanning it (for what reason I have no idea, its bloody youtube). It's scanning is causing the stream to lag, turning my music/video/whatever into the sounds of a dialup modem. I went into the settings per some information I found and turned off Intelligent Streaming and Script Scanning, and it's not fixed it. I'm honestly getting close to chucking it in with McAfee and Norton, because since I paid for it I've had a lot of problems with it.
