I used to have major spyware/malware problems, which, with the help of the Geeks to Go Malware forum, I was able to remove, and am now clean. However, since the malware problems started, and even now that I've removed them, I still have problems with any movie file that is an avi. WMV's, mp3's, and (most) mpg's play properly, though some mpg's cause crashing. I am referring to files that played fine before the malware problems, and now do not work.
Specifically, if I try to play such movies, regardless of the player - I've tried Windows Media Player 10, Media Player Classic, Bsplayer, WinAmp - I will get an error message saying the file cannot play, and then my desktop will crash. I know I have the proper codecs to view the files however, since I've checked the files' codec requirements using the Gspot codec checker.
It's not just an inability to play the files though. Everytime I am browsing folders in My Computer/Windows Explorer, if the particular folder I am looking at has an .avi file, after a few minutes, I will immediately get Windows' "Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience." dialogue message with the "Send"/"Don't Send" error report options, followed by my desktop crashing for a few minutes before recovering. If the folder contains other types of media, not including .avi's, there is never a crash.
I've tried uninstalling and re-installing my codecs, using different players, and creating a new XP user account, but none of these have stopped the crashing/failure to play problem. I could use any help, so thanks in advance.
