Or use Linux instead. I have run it since 2009 on many computers and have yet to be affected by any virus or malware. For the truly paranoid, boot your computer from a Linux thumb drive. In retrospect, Windows security (or the lack of it) was such nonsense.
For some of us, Linux just isn't the right tool for the job. I use Linux all the time for the text manipulation tools. I've built and manage a number of Linux based application servers. I built Linux servers as our premises relay servers. I like Linux.
But I can't use Linux to manage our Exchange servers, Active Directory, Azure Active Directory Connect, Active Directory Federation Services, Office 365, etc... I need to use Windows in order to manage those systems.
It's important to use the right tool for the job.
