- Backup your data files regularly. I cannot emphasize this enough.
- Keep your system up-to-date by performing updates from Apple or Microsoft.
- Be careful what you download or click.
- Hard drives fail, DVD drives stop working, cables go bad, speakers stop suddenly. Don't be too surprised when these things happen.
- Know what security (anti-virus, firewall, anti-spyware) software you are using so you can tell if something is amiss. Keep the anti-virus/anti-spyware software up-to-date and run scans weekly or at least monthly.
- Use a surge protector.
- Nothing lasts forever.
