This is a simple Word macro virus.
It creates the following macros to NORMAL.DOT: AutoOpen, WordSystem, WinUpdate, FileSave and FileSaveAs - unless the user is running Portuguese version of Word. In that case, the last two macros are replaced by FicheiroGuardar and FicheiroGuardarComo.
Disinfection & Removal
When the virus infects a machine for the first time, it attempts to display a dialog box with these texts:
MoRTaLs aRe UnaBLe To HanDLe THe PoWeR ! ! ! GOD LIVES IN HELL...
When 100 files have been opened after infection, the virus tries to delete the current command interpreter. This would prevent the machine from booting.
WM/Razer.A was reported to be in the wild in UK in early 1998.
