Virus Memory Kill V1.0 © Chris Hames. 10th June 91.
(REMEMBER! no virus can copy itself to a write-protected disk.)
This utility is different to the previous versions in that it no
longer directly detects any virus. Instead it is now the most powerful
tool for detecting new viruses. It checks a heap of things that viruses
use and tells you when they have changed.
Firstly it checks CoolCapture, ColdCapture, WarmCapture, KickTagPtr
and the KeyboardReset to find anything that is trying to survive reset. If
any of these are abnormal it will alert you including a display of the area
of memory that they are pointing to. You can look for words describing was
the thing is and then decide whether to do nothing or do a cold reset(note
this is much more that just a normal reset) which should clear memory of the
virus.
Secondly it checks the jump tables of all resident libraries, devices
and resources and warns you if any are not pointing to ROM. It will give
you a message describing what isn't pointing to rom and where it is actually
pointing. Most systems will get at least a few of these warnings. Setpatch
causes a few and other legit programs do as well.
FOR PEOPLE WHO DON'T UNDERSTAND A WORD I AM SAYING:-
This program is very technical I agree but a general user can just
have it in their startup-sequence and notice the messages it gives. If
they change and you haven't changed your system get the latest best Virus
Killer(One that checks your disks and files) and run it to check out your
system.
ALERTS THAT ARE CAUSED BY LEGIT PROGRAMS
Please note some legit programs will cause alerts.
SetPatch r (Workbench 1.3 command for 1/2 meg chip uses with RAD)
Changes the coldcapture.
RAD changes KickTagPtr
Stopping Alerts/Warnings that are caused by legit programs:-
You can stop a alert/warning by giving the full cause of the alert
which is best idea
eg -$01E(graphics.library)=$66666666
eg KickTagPtr=$77777777
You can stop a alert/warning by giving the full cause without the
location of the alert which is second best idea
eg -$01E(graphics.library)
You can stop a alert/warning by giving just the description of the
of the alert which is the worst idea
eg KickTagPtr
eg (keyboard.device)
Usage: VMK -ca alerts
-c will cold reset(this should kill any virus from memory)
-a will make library/devices/resources warnings into alerts
with memory display.
Examples of use:-
VMK -c ; Resets your machine safely!!
; (Should kill ANY virus from memory)
VMK KickTagPtr ; Stops alerts about the KickTagPtr (Say if you use rad)
VMK KickTagPtr=$00000700 ; Stops the specific alert at this location
; eg If RAD always at same location use it
VMK (dos.library) ; Stop all warnings/alerts about the dos library
VMK (dos.library) -$01E(graphics.library) ; no dos &
; no -$01E graphics alerts
If you find a new virus send it to:-
Erik Lovendahl
Snaphanevej 10
4720 Prst
Denmark
