Adguard
AdGuard is a macOS ad blocker and privacy tool that filters ads, trackers, and malicious websites across browsers and many apps.
What is Adguard?
AdGuard is a native macOS security and privacy app that helps users block ads, reduce tracking, and filter web traffic across the system. It is designed for people who want cleaner browsing, fewer intrusive pop-ups, and extra protection from phishing and fraudulent pages while using Safari and other Mac browsers. Beyond browser use, AdGuard can also filter traffic from many desktop apps, which makes it useful for users who want broader ad and tracker blocking than a browser extension alone can provide. The app includes tools for custom filtering rules, DNS-related controls, privacy settings, and site-specific adjustments. AdGuard is published by Performix OOO and is commonly used as a system-wide content filtering utility on Mac.

Safety overview
Status: Mostly safe
AdGuard is legitimate security and privacy software, but it works by filtering network traffic at the system level, so it may request elevated permissions during setup and can affect how websites or apps load. That access is normal for an ad blocker with system-wide filtering on macOS. If a site or app stops working correctly, pause filtering for that service or review its exceptions rather than assuming the app is harmful. Keep it updated and install filters or companion components only from AdGuard itself.
Recommendation: Keep AdGuard if you actively use it for ad blocking, privacy filtering, or safer browsing on your Mac. If you no longer want system-wide filtering or prefer a lighter browser-only setup, you can remove it; some websites or apps may then show more ads or trackers.
