But even about the Viruses. I haven't used an anti virus since 2003, simply because I know enough about computers to exercise good common sense. Here people seem to think that if you just turn on a Windows computer it will get a virus. Anti viruses are mostly for people who don't really understand computer, and like to google celebrity pics, or naughty pics.
You don't seem to understand that worms and other things can affect a Windows box even through no user action.
You have to be exceedingly vigilant on a Windows box to avoid these kinds of problems.
I was very similar to you, a power user who took extreme pride in my ability to keep my Windows machine running well through common sense.
Even then it turns out that my machine had become infected.
The bottom line is that the typical user who is just browsing the internet and leaving a computer connected 24/7 should not have to install and manage security suites just to avoid having problems.
Power users might be able to avoid having issues with Windows PCs but typical users have nothing but problems.
