Disinfection & Removal
Allow F-Secure Anti-Virus to disinfect the relevant files.
For more general information on disinfection, please see Removal Instructions.
When an infected document is opened the virus copies itself to the global template. Then it infects every document opened or saved with "File/Save As" menu.
At April 4th the virus activates its payload when a document is opened. It then attempts to format the "C:" drive and displays a message box with the following text:
Its cool DuDe's Birthday!!
The virus also hooks two menu selections. "File/Print" inserts an additional "z" character to the current position of the cursor before printing and "Tools/Macros/Macro" does not do anything.
