My xvid's do not work

[Luso Navigator]

i was donwloading several divx movies at the same time.one of them wich i can't identify,when finished wouldn't play,and forced the media player to close and the Win Explorer as well.The same happened with all the other downloads.sometime after that all the xvid movies i had previously on my hard made the same.it won't let me even underline the main folder where i keep them.
I tried to search with avg kaspersky and trend micro for something but nothing worked.
if any of you guy's can help me that would be greatly apreciated.

I guess you have missed the forum rules, so pay attention next time! Have a look at rule 6. Closed thread.
