9. There is so much money now in computer security, and so many companies making a profit, that it gives these security companies a self-interest in CREATING viruses and making people be insecure and feel insecure, without their security "solution".
(This isn't something I believe, but it is interesting to note)
Indeed, the ultimate solution is to lift the awareness, and the carefulness of all users - and that is an almost impossible task*. Still, it would be an interesting one. Has anyone searched for sites that try to do this for users? That would be an interesting venture, I'm sure other users here will agree. What we may call common sense by now is afterall, the best form of real security, and something most people don't pick up on. PC mags have their occasional "10 DON'TS for computer security" - but they are well deficient compared to a resource that aims to get readers to understand, which is what I have in mind (I'm sure these resources are out there).
* it really is, however there are things the software can do to get users interested in their security. For example, it was only when I switched to GNU/Linux that I really understood why a user should never be the root/admin for daily tasks, and it was that point where I began to understand everything I know about security. I'm positive there are an abundance of users still nowadays who wonder, perhaps frustratingly, why they need to be 'root' to make changes to the computer, and they search, and they find an answer that teaches them, and they certainly will understand not to use the root account for their daily needs.
