What is a buffer overflow?
Hello.

When trying to watch a movie on a disc my virus scan came up saying a buffer overflow had occurred. The video file wouldn't play either. So I closed it and tried again but now Windows Media Player wont open at all. I've had this happen before and I had to restart the computer to get it working again but I would like to know how to prevent this from happening.

Thanks.

Is it a standard video played with a commonly available codec or did you have to go download a codec to play the video? If the latter, you downloaded a viral agent which of course has no intention of playing any video and uses a buffer overflow attack/technique as a means of getting on your system and gaining a degree of control or fucntional independence. If the former, its probably a corrupt file or something has happened to WMP and its causing the buffer overflow.

If you know its a valid video file then you can further diagnose by trying to play it with other media players such as VLC media player to see if its a problem with the video or a problem with WMP or the implementation of the codec associated with the video format.

oh.

Well it seems that I uninstalled my Avi codec pack for some reason, probably because Crysis told me I had an emulation conflict and that was the only thing that was even remotely related to emulation.

So I just installed it again, thanks anyway.
