Use the latest OS (Operating System) – The most recent OS is generally the safest. Microsoft’s Windows 10 is their most up-to-date OS, and anything earlier should really be upgraded. Don’t forget that free software updates are issued all the time. Take advantage of these and update regularly.
Install security software – The main threats to your online security are hackers, viruses and spyware, (this last one is a programme that may be used to log your credit card details). Ideally you should have a firewall, plus antivirus and anti-spyware software as an absolute minimum. You really need all three, because individually they won’t protect you against every attack. Be sure to update them regularly.
Ditch the SPAM! – As far as possible don’t open anything you think is SPAM. Use ‘disposable’ email addresses for registrations on sites with which you’re unfamiliar and use SPAM filter software.
Wi-Fi Wisdom – Wireless networks can offer an easy way for people to eavesdrop on your PC. Because they use radio waves, anyone within range can pick up the signal, making them a target for hackers who could be after your financial details, as well as freeloading unauthorised users who might piggyback your signal to access your broadband connection. Use an up-to-date router. Make sure you rename your network to make it more difficult to find, create a unique password and always turn on the encryption.
Backup! Backup! Backup! – Just in case. Backup all your data regularly and from time to time check the backups.
