Tips for hardening computers

  • Patch your Microsoft operating system automatically.
  • Patch Adobe products such as Adobe reader regularly.
  • Uninstall any software you don't need on your computer.
  • Use strong passwords or passphrases for all user accounts on your PC.
  • Use and properly maintain good antivirus software, and optionally anti-spyware software.
  • Use a firewall, such as Microsoft Windows built-in software firewall.
  • Do not open suspicious email attachments or respond to suspicious requests.
  • If you're not using it, disable the Windows File and Printer Sharing service.
  • Lock your PC's screen when you step away, and shut down your computer when you'll be gone for more than 4 hours.
  • Where possible, consider using a web browser other than Internet Explorer, and treat all "free" software with suspicion.
