Regularly update your anti-virus/malware software. Save important documents and photos on an external hard drive or the Cloud. Make sure you download the latest operating software, browser and app updates as they contain vital security updates that help protect your device from hackers, viruses and identity theft. Not keeping your software up-to-date can result in serious issues, which can not only affect your computer, but your personal security too.
