Shutdown your computer

A simple and low-tech solution for computer security is simply shutting down your computer when it is not in use. End user computers do not run mission critical services and therefore do not need to be on 24/7. When your computer is off no virus, spyware or hacker can penetrate your system, if your computer has been compromised it cannot attack and infect other hosts. It is a simple win-win situation that is also saves electricity.
