DeadWin.1228

Description DeadWin.1228

These are memory resident encrypted parasitic stealth viruses. They hook INT 21h, and write themselves to the end of COM and EXE files that are executed or closed. When an infected file is opened, the viruses disinfect it. While infecting, the viruses can corrupt files.
The viruses check the names of files that are executed, and if the file name begins with "WI" (WIN.COM), they run their trigger routines (see below).
The virus checks the system date and time. If the system date is November 13th or June 21st, it formats the hard drive and displays the message:
hard disk destroyed!
On Fridays, when WIN.COM is executed, this virus checks the system timer, and if the hour counter is equal to the second counter, the virus displays the following message, and reboots the computer:
Dead to Windows!

Death.1001

Description Death.1001

Death is a not dangerous non-memory resident encrypted parasitic virus. It searches for .COM files (by using the mask "*.COM") and writes itself to the end of these files. On the 10th generation it types the message "Bad command or file name" and leaves in memory a memory resident program which hooks onto INT 09h (keyboard). When the Alt-Ctrl-Del keys are pressed in combination it types the following message and hangs the computer:
Your PC has lapsed into a higher state of beingall
D E A T H
Please, feel free to cold boot,
as nothing has been damaged,
it was only a near death
experience
Your PC should meditate more often,
'cuz with all the evil viruses
flowing around neurospace
we wouldn't want this
to become a real
