Strange avi problem

I have a strange problem with avi playback in that sometimes when I open a particular .avi file with wmp, it will run properly, but if I close the player and run that same file again, it gets stuck on that same frame. It is not only a wmp problem too, because when I try to use some other player like winamp afterwards, it also gets stuck. According to Gspot I ahve no missing codecs either and it does not say the file is corrupt. This happens with multiple .avi files I have. Any ideas as to what’s wrong?

I think you possibly have the gvb virus that has been making its way around the net. So my best advice to you is to check anything you have dl recently. The bug can really fuck your computer up....not to mention your squirrels too.

Well I scaned my computer with Norton Anti-Virus and Spybot and I don’t seem to have any viruses or malware, so I’m not sure that’s the problem. Also in my first post I meant that when I try to open any avi file again, it gets stuck on the first frame. It is not just for the file I just openned. Do you have any other suggestions? Thanks

Help! Can no one else offer a suggestion? This problem is really annoying and I would really appreciate any help on fixing this odd problem.
