Author's notes

Some retro/anti-debug technics, safety checks and error handling. It infects on: execute, open, ext. open, delete, attrib, rename, create and close !!! The virus code is based on no-frills code, using direct manipulation of the MCB chain. Size is 1000 bytes. This is just a funny virus, with funny payload and so on, nothing really groundbreaking or new. The code is commented, so newbies may learn from it. Feel free to use some of the code in your own virus if you like to.
