Youtube videos were working perfectly an hour ago, but now the videos don't even buffer. I've tried flushing my dns, ip config /release & renew, deleting my cookies, rebooting, resetting my router, all sorts of stuff. My anti virus is Eset Smart Security. I've downloaded the latest adobe flash player, my java seems to be up to date. I don't know what could be the problem to be honest. I've tried watching videos on Internet Explorer but I get the same result. My download speed has greatly reduced aswell, it took me about 5 minutes just to download 800 KB. My ISP is Comcast and I am NOT considering switching. Any help is appreciated.
