what is your worst virus experience?

In 2008 I tried to become a hacker, I was a stupid 14 year old. I downloaded an old hack software which I can't find anything about on the internet anymore, but it was called pro rat. I infected my own computer with a remote attack trojan to test it out and hit the button "matrix chat". Welp, I got a matrix chat screen, managed to send one message and get all my drivers deleted.
