This is an encrypted virus. It contains two macros: XxGRUNTxX1 and
XxGRUNTxX2. Because this virus has no auto-macros, it takes control by
assigning the ‘E’ key to “XxGRUNT1xX1” macro, and the ‘I’ key to
“XxGRUNTxX2” macro, i.e. when ‘E’ or ‘I’ keys are pressed, corresponding
macro takes control. MS Word saves these redirections in documents, and
these keys are automatically assigned with macros when Word is opening an
infected document or global macros.
The virus does not manifest itself. It contains the string:
A Virus from Nightmare Joker’s Demolition Kit!
