More and more viral procedures carry on to the computer data destruction, some viral more direct formatting hard disk district. 
    Actually, we may use the poor life to make to prevent the viral procedure to hard disk's destruction operations and so on formatting. 

    Opens C with “the memorandum” under the packing table of contents the Autoexec document, and increases the following sentence: 

    C:\ >DOSKEY FORMAT=Bad command or filename! 
    C:\ >DOSKEY del=Bad command or filename! 
    C:\ >DOSKEY deltree=Bad command or filename!
 
    Then saves the plate to withdraw then. When again this transfers orders and so on FORMAT, DEL, DELTREE, will demonstrate that Bad command or filename will refuse to operate.
