Eli5 – How are computer viruses created without destroying the creator’s computer first?

Question

I’ve always wondered how computer viruses are made. If someone creates a virus on their own computer, wouldn’t it infect and potentially destroy their system first before it’s spread to others?

Answer 1

i would install linux on a sd card and create the virus from there. you can easyly make clones of that installation by using the DD command, so if you got 3 sd cards, you will always have a working os you can copy.
