Technical Details

Major tries to interact with the Major BBS system. Without further information on this BBS system, it is impossible to tell what the virus actually tries to do. In any case it tries to access files

\BBSV6\BBSAUDIT.DAT and \BBSV6\BBSUSR.DAT.

Major contains these encrypted texts:
   The Major BBS Virus created by Major tomwn to DOS
    Puppet Image Gnat Minion Cindy F'nor
	
	

As many other memory-resident viruses, Major will conflict with some memory managers.

Major virus has been confirmed to be in the wild in several countries.
