What more would you like to learn?

I would like to learn about computer viruses as how to prevent catching one and what to do when my computer became infected with. I used to think it was actually a "virus" like same as the cold virus and not only computers, but so as people could get infected with them. I was totally wrong about this idea, but still i do not know much about them. I think computers and the internet can be a lot safer and more usefull, if I was aware of those risks about computer viruses.
