Here is some good advice for things you should and shouldn't do when it comes to using a computer in a sane and useful manner.
  • Do pay attention to the User Account Controls (UACs) warnings. They imply that a setting change affects the entire system or could post a security risk.
  • Do run a firewall, and allow expected traffic to access the local network and Internet. Only deny unexpected firewall requests.
  • Do run PC security software, such as Windows Defender. Keep the software activated and updated.
  • Do install Windows updates as they arrive.
  • Do classify public wireless networks as Public whenever you make a connection.
  • Don't open the PC's case unless you first turn off and unplug the thing.
  • Don't run the Defrag utility on an SSD, a media card, or a thumb drive.
  • Don't open unexpected e-mail attachments.
  • Don't reply to alarmist email messages or requests for access to certain websites. When in doubt, phone the business claiming to send the message to confirm that it's legitimate.
  • Don't download unknown software from the Internet.
  • Do pay attention to the prompts when downloading software to ensure that you're not automatically installing shopping buddies, toolbars, or alternative search engines.
  • Do update your wireless router's settings upon initial configuration.
  • Do remember that "stuff" happens.
  • Don't blame yourself when the computer crashes.
