3. Protect yourself with Windows Defender
Windows 10 is the most secure version of Microsoft’s OS ever made, but this is partly because Windows Defender comes in ever installation.
Enable Defender by going into All settings>>Update & security>>Windows Defender. Make sure real-time protection and cloud-based protection are turned on.
And if you have other virus blockers pre-installed, we recommend you remove them immediately using their own uninstallers. Third party anti-virus can be major resource hogs.
