My problem is that when I select and individual or multiple video files at once, the explorer process in task manager consumes 50%+ of the CPU. I have scanned with AVG, S&D, Ad-Aware and have found nothing. This problems seems to happen only to a network shared folder containing nothing but video files. I have included my hijackthis log if that helps. Also this is a fairly recent installation of XP Pro.
