Cloudfare WARP is a free app that makes your internet safe. It includes a secure DNS, encrypts traffic from your device (laptop, desktop, cell phone etc) to the internet. I recommend configuring it with 1.1.1.1 for Families option with malware protection so that you get free malware protection also.

There are a few similar services - some of them free and some paid. techblog.nexxwave.eu/public-dn…

Considering protection level and ease of installation and use on different type of devices, availability across different regions of the world, I consider Cloudfare WARP the best. I would consider quad9.net a close second.
