The author of the Fu Manchu virus seems to have intended to write one of the most humorous viruses around. He started with the Jerusalem virus, removed the harmful part of it and added several new features:
The virus will censor the text the user types, deleting two four letter words.
It will also take action if the user types "Thatcher", "Reagan", "Botha", or "Waldheim". In those cases it will add comments to the text.
When Ctrl-Alt-Del is pressed, the virus will display the message
The world will hear from me again!
The author also corrected some minor bugs in the Jerusalem virus.
