What our analysis found
AdGuard AdBlocker, used by 17,000,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in October 2026.
This is the legitimate AdGuard AdBlocker by Adguard Software Ltd. (Google-trusted publisher, 16M users, 6+ years on CWS, ML score 0.00, permhash cluster malicious). All source code reviewed is consistent with standard ad-blocking functionality: ` ` implements the W3C Global Privacy Control spec and document referrer masking for privacy; the ` /` directory contains no-op stub replacements for tracking scripts (FingerprintJS, Google Analytics, Scorecardresearch, Matomo, etc.) that AdGuard injects in place of the real trackers—these are anti-tracking scriptlets, not fingerprinting code. The ` ` includes only the webextension-polyfill library (v0.12.0, credited). Third-party risk score corroborates: likelihood with 'good user rating', 'high user count', and 'featured extension' all listed as Good signals. The high ML pattern counts (js_innerhtml=171, js_appendchild=270, js_xmlhttprequest=238, js_exclamation=25983) are explained entirely by minification and the DOM manipulation that is inherent to any ad-blocking extension.

About this extension
Unmatched adblock extension against advertising and pop-ups. Blocks ads on Facebook, YouTube and all other websites.
Read the publisher’s full description
AdGuard ad blocker effectively blocks all types of ads on all web pages, even on Facebook, YouTube and others! ## What AdGuard ad blocker does: ★ Blocks all ads: video ads (includes YouTube adblock), rich media advertising, unwanted pop-ups, banners and text ads (includes Facebook adblock); ★ Speeds up page loading and saves bandwidth, thanks to the missing ads and pop-up windows; ★ Protects your privacy by blocking common third-party tracking systems; ★ Blocks many spyware, adware, and dialer installers; ★ Protects you from malware and phishing. ## What are the advantages of AdGuard over Adblock or Adblock Plus? ★ AdGuard ad blocker is really fast and lightweight. It uses half as much memory as other popular solutions: Adblock, Adblock Plus, and even outperforms uBlock Adblocker in some tests; ★ AdGuard can handle most of the adblock circumvention scripts; ★ AdGuard is simply better looking and modern (in our opinion). ## How can AdGuard ad blocker protect your privacy? Privacy protection is one of the main goals! Just enable the "AdGuard Tracking Protection filter" in AdGuard settings. It completely removes all forms of tracking from the Internet. AdGuard has one of the largest tracker filter lists containing more than 10,000 rules. It is even larger than the databases of Ghostery® and Disconnect. ## How to remove social media widgets with AdGuard? Tired of all the «Like» buttons and similar widgets infesting all of your frequented web pages? Just enable AdGuard "Social media filter" and forget about them. ## How can AdGuard ad blocker protect you from online threats? At the moment we’ve got more than 2,000,000 harmful websites on record. AdGuard can block domains known to spread malware, protecting your computer against viruses, Trojan horses, worms, spyware, and adware. AdGuard really lowers the risk of virus infections and prohibits access to harmful websites to prevent potential attacks. ## Crypto-jacking protection We did comprehensive research on crypto-jacking and, as a result, AdGuard can reliably block most of the known crypto-jackers including CoinHive. You can also add some open source filters like NoCoin which will give you an additional layer of protection. ## Why does AdGuard require permissions? * "Access your data for all websites" and "Access browser tabs": both permissions are necessary for AdGuard to apply all kinds of cosmetic processing to the pages' content. Naive ad blocking would simply block ad servers, and leave broken elements and first-party ads on the pages. AdGuard applies special cosmetic rules to make pages look clean and tidy. * "Access browser activity during navigation": this permission is necessary to keep track of navigation events in order to apply rules when the time is right. ============================== Release notes: https://github.com/AdguardTeam/AdguardBrowserExtension/releases ============================== Free and Open Source: https://github.com/AdguardTeam/AdguardBrowserExtension
