Logic Behind The Working Of The Virus
If I don’t explain the logic(Algorithm) behind the working of the virus,this post will be incomplete.
So I’ll explain the logic in a simplified manner.Here I’ll not explain the technical details of the program.
If you have further doubts please pass comments.
LOGIC:
1. First the virus will find the Root partition (Partition on which Windows is installed).
2. Next it will determine whether the Virus file is already copied
(Already infected) into X:\Windows\System
3. If not it will just place a copy of itself into
X:\Windows\System and makes a registry entry to put this virus file onto the startup.
4. Or else if the virus is already found in the X:\Windows\System directory(folder),
then it just gives a command to restart the computer.
This process is repeated every time the PC is restarted
NOTE: The system will not be restarted as soon as you double click the Sysres.exe file.
The restarting process will occur from the next boot of the system.
AND ONE MORE THING BEFORE YOU LEAVE(This Step is optional)
After you compile, the Sysres.exe file that you get will have a default icon.
So if you send this file to your friends they may not click on it since it has a default ICON.
So it is possible to change the ICON of this Sysres.exe file into any other ICON that is more
trusted and looks attractive.
For example you can change the .exe file’s icon into Norton antivirus ICON itself
so that the people seeing this file beleives that it is Norton antivirus. Or you can change it’s
ICON into the ICON of any popular and trusted programs so that people will definitely click on it.
The detailed tutorial on changing the ICON is given in my post How To Change
The ICON Of An EXE File .
