W97M/Arbeit is a Word 97 macro virus with a destructive payload.
Disinfection & Removal
When an infected document is opened, W97M/Arbeit.A disables the built-in macro virus protection, the status bar and the following menus: "Tools/Macros/Macro" and "Tools/Macros/Visual Basic Editor". It also modifies the user name and initials to:
User name: NoWork Inc. Initials: NWI
Then the virus creates a temporary file "C:\mlpog.sys" that it uses to infect the global template and all documents closed after that.
The virus activates its payload every day after October 15th, when it shows a message box with the following text:
The technology will be kill humaneness
After the message box has been shown, it deletes all files from the root directory of the "C:" drive.
