Technical Details

The virus activates when ctrl-alt-del is used. First it displays a close-up ascii picture of a face and then it displays the following message and waits for a keypress:

Nothing can save you here, friend - you're in my world now!  

The virus also modifies batch files by adding an ECHO line at their end:

@ECHO I'm watching you!  

The virus also contains the text 'MadMan'.
