Sub-Zero is a memory resident COM and EXE infector that is based somewhat on
on Jerusalem-B. It is the ansestor to the virus Captian Trips
which at this time has not been nailed by SCAN.

Be carefull because this virus will most likly format you hard drive if you
run it on the wrong day. One day of the year it will perform a HD format.
I think it's in June, hmmmm... D-Day rings a bell.

As of Scan-77 this virus can not be detected by SCAN or F-Prot.
