Description: Details
Ph33r

It is a harmless memory resident parasitic virus. While executing an infected program the virus hooks INT 21h and stays memory resident. In case of DOS host file the virus uses the standard methods of the INT 21h hooking, in case of NewEXE file the virus uses DPMI calls.
While opening, execution, renaming executable files including NewEXE, and on changing the file attributes the virus writes itself at the end of the file. The virus checks the file length and infects only *.DL*, *.CO* and *.EX* files. The virus does not infect the *AV.*, *DV.*, *AN.*, *OT.* files.
While executing COM and EXE files the virus writes itself to the end of the file. While infecting a NewEXE file the virus moves NE header 8 bytes up, creates new descriptor there, and writes itself the end of the file.
The virus does not manifest itself. It contains the text strings:
=Ph33r=
Qark/VLAD

On October 21st "Ph33r.1460" displays:

Happy Birthday to you, HandSome Boy!

> Joan for Windows v1.0 of T.N.T. Taipei/Taiwan 1995/09 <
