I have Windows Defender installed, and whenever I open the My Videos folder, which contains tons of movies, Windows Defender warns me that malicious code is being run, and it has to close explorer.exe.

While I can sorta play some of the movies (by having the expand folder option for My Documents on the Start menu) some of them completely crash media player when they run, while some others play fine. My problems began at the same time I installed a DVD burner and Nero from NewEgg.com, except I dont know how that could be related. I have yet to encode or burn a single movie, and I installed the drivers via the included disc, then updated them and the firmware. I also installed, then quickly uninstalled, the Nero 6 suite that was included because I suspected it to be the problem (it would crash often when going through a directory and trying to select a file).

Also, I tried running Windows Defender to find what was the cause, and it found nothing in detailed scans. I also used AVG, and Spybot to find it, again - nothing. I renamed the folder to My Videos1 - that had no effect. I copied several of the movies into c:/temp/videos/ and the problem was passed along. The only thing I can think of, is that there really isnt a problem, and I should allow an exception for this folder in Windows Defender, as suggested by MS when I see what to do about the problem. However, I am leery about this, and have held off on doing so.

EDIT: the program which reports the problem to MS sometimes crashes in the same way also, during the reporting phase of explorer.exe's shutdown.
