Don't know whether this is an infection or not, but I figured I'd post here first.
I'm suddenly having trouble loading 50% of Youtube videos, either directly from the site or from links. Mostly I get the spinning buffering arrow but the video never plays.
This started happening last week after I tried to play an embeded vid in another forum. The video was unusually choppy throughout, so I went to Youtube to play the vid directly. This time the vid wouldn't load at all, then I noticed the same thing happening when I tried to play other Youtube vids at random. It's a crap shoot. Some work, some don't, regardless of the vid's length.
I've already tried deleting my temp internet files, history, and cookies within IE, then rebooting. No dice.
