Technical Details



Variant:Arbeit.A

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.
