Guy's let me be serious for a few moments.
I repaired computers for many years. The most common problem that I repaired was the end results of viruses. When I showed the owner what was done, and the information that the owner had made available to hackers, and how to prevent it from happening again, they would say okay, pay me and leave. Needless to say, I had a lot of repeat business.
I retired ten years ago. The world is much more connected today and there is a hacker around every corner.
