Concluding Part –
These were the Virus Source Codes. Since you will create these viruses in Notepad using Batch Script anyone can easily find out your deeds and delete it if they find it to be harmful.
But you can get over with this drawback as well by using the tool – ‘Batch to Executable Converter’. This will convert the .bat file extension into the ‘.exe’ file extension and this Batch file will be converted into a Windows 10 Application.
I assume you have all found these source codes of some good use. And I hope you have not done it on your own PC. This article was meant for knowledge purpose and any misuse of it is not encourage.
Thank you.
