The same here, well, over 34 years of Windows and never had a virus, adware, trojan, worm, ransomware or any other malware in that time. Apple System/Mac OS/OS X/macOS, the same.
I've only been using Linux since 2001, but it has a clean record as well, even though there is Linux related malware out there, just look at the IoT infiltration malware out there, where most of those IoT devices use Linux...
iOS and Android even shorter time, but no infections.
Just because you haven't been bitten, doesn't mean that there isn't malware for a platform out there, in the wild. The Western Digital NAS debacle last week, anyone?
If you secure your device and are careful, what you do with it and where you go etc. you can minimise the risk, but the risk is still there, regardless of the platform.
The default configuration, of having the primary user an administrator, on Windows is as shambolic today, as it was 20 years ago, when XP came out. But anyone with any sense leaves that account for admin purposes and uses an user account for everyday use.
We are domain admins, but we use non-domain administrator domain accounts for every day work and we don't even have local administration privileges on our own PCs. We have to use a separate administration account, when we want to install something or change the configuration, just like we do on our Linux boxes.
And I use that at home as well. My main Windows PC is used with a standard user, with an administration account in the background for administration purposes only. The same on my home Linux boxes.
