I've had nothing but trouble since updating overnight. Horrid lag, not being able to open games, pages, AOL, your own program. But the worst is that now videos do not play properly. The sound is fine, but the picture is either a grey cottonball haze or a tiny slice of pixels. Videos play properly in every other browser I have (AOL's, Firefox and Chrome.) I've run multiple scans/diagnostics and it's still not right. I'll either be rolling back to a point prior to this update or removing Avast completely.
