What is the strongest computer virus ever and how do u make it

I love you was the strongest computer virus.

Explanation:

Now to make it I mean not hard when it comes to when it was a vbs file and you can simply right click it and edit with notepad or some other text editor.

Ok to make it just make something like a bat file that will email everyone in your email outlook and it sends a other file that does the same as this script but it does other stuff to the computer.

And I love would not work today due to the main reason it was a big deal was ppl thought it was a text file. They would see the .TXT and the VBS at the end. There are worse then I love you .I had seen was Chernobyl witch would fry your bios. It's a hard answer but I love you did like over 8.7 billion in costs of damage so I love you is up there
