It is a dangerous nonmemory resident parasitic virus. It searches for COM files except COMMAND.COM, then writes itself to the end of the file. On December, 30th it overwrites the AUTOEXEC.BAT with the instructions:
@echo off
echo PUFessional Anti-Windows Virus v1.2
PUFAWV12.COM
Then the virus creates the PUFAWV12.COM file and writes to there a program that halts the computer. The virus then reboots the computer.
