(Only supports Windows now, but made in Linux) This Virus was created using Python library Tkinter. This virus is basically harmless. It doesn't let you close the window so easily(without killing the terminal) and just clicking a button can create a window, you can create as many windows as you like by clicking it.
Well there were many ways to do so, But I used this library which made it so easy to change it. A tutorial for the same can be found here.
I guess I will continue to make more normal viruses(or scripts ;-;) like this in the future while learning GUI Python.
To get the source code, you can download the app.py from above
You can download the .EXE from the releases pane or directly here. Just extract the compressesd file and you will find the .exe file named as Indo.exe(I will change the from next time :/)
