Dangerous AVI files? Is any application which can open a media file under attack?
Can `*.avi` or any media file contain any script or dangerous code?
Today i saw following message in **Microsoft Security Essentials**:

    Category: Trojan Downloader
    
    Description: This program is dangerous and downloads other programs.
    
    Recommendation: Remove this software immediately.
    Items: 
    containerfile:C:\Users\...\amediafilename.avi
    file:C:\Users\...\amediafilename.avi->(ASF_Script_Commands)

if it's true:
Commonly any media player opens file in read-only mode and they can't create a file in hard disk without user permission. Is any programming tecnique here or what? 

The main question is:Did any application that we create have some bug like players and we dont know?
