Just the other day, I ran into another person who told me they don't run anti-virus software on their home computer. I looked at them in disbelief and asked why they would expose their computer/personal information to the potential danger? The response I got was, "I've never had a virus on my computer before". As I explained to this person that they have every right to not run anti-virus software, I cautioned them and asked that they looked at the risks they were taking.
Good luck in whatever you choose to do.
