Points all active adapters at Cloudflare's 1.1.1.2 / 1.0.0.2 'for Families' resolvers, which block known malware and phishing domains at the DNS level — a free, zero-config layer of protection. One-shot: undo with 'Reset DNS to automatic'.
MaxTweaks applies this tweak with one click and clearly marks it as a one-shot action so you always know what can and can’t be undone. A System Restore point is offered before batch changes, and every tweak links to its official source.
