Update your operating system (OS)
Cyber threats are changing all the time. Up-to-date operating systems and apps are your first line of defence against many bugs and viruses.
Updates aren’t just about adding new features. They’re also about fixing vulnerabilities in an OS or an app that attackers could use to gain access to your system.
Updating your OS can protect against cyber-attacks
When an update for an app or your OS pops up on any of your devices, install it right away.
Set and forget
Set your system preferences to install updates automatically – then you don’t have to think about it.
Only keep the apps you need
Don’t use it? Delete it. That way it’s easier to keep the apps you use up to date
