How You Will Compile This Code

Step 1 :

• First You Will need Borland TC 3.0
• Copy these code into the compiler and 
• then press Alt+F9, it will compile the code.

Step 2: 

• How to generate these code in to the exe file of the virus
• >press F9

Note:

• Remember Do Not Press CTRL+F9 as this will infect your system also.
• And also Check the size of the generated exe file in Bytes.

Step 3:

• Modify the value of X (which is 89088 initially) in the code above with the size noted in above step.

Step 4:

• Go to step 1 and step 2 again
• the exe file obtained now is the Virus and is ready to infect other systems.

How To Test:

•   Make a new folder and put some (any) exe files in it.
•   Also put this virus in it.
•   Run the virus and you will notice that the other exe files will get infected.
•   All the infected files are ready to reinfect.
