Once installed in memory the virus also uses int 1Dh, normally a
pointer to some video information, as a gateway to call the
original int 21h. A new int 1Ch (timer) handler is installed.
It plays with the display controller, effectively shaking the
picture on a standard VGA machine.
Zarma is also a retro-virus : it is able to deactivate VSAFE,
VDEFEND and VWATCH.
The virus contains the following text:
ZARMA-VIR by T. Power *** Claudia Schiffer Lives !!!..
