The Security & Privacy Center is a console of tools, features, and settings that allow you to customize your online safety.

In the Security & Privacy Center, you can view all the built-in tools and features available. By using these tools, you not only create a more secure browser, but a more secure Mac.

What is Anti-Fingerprinting?

Websites and ad networks can use your unique browser configuration, referred to as your browser fingerprint, to track you. Your browser fingerprint is comprised of data related to your device configuration, browser, and history of your online behavior, which is continuously stored while you interact with webpages. Anti-Fingerprinting helps disguise your digital fingerprint to prevent websites from identifying and tracking you without your consent.

The Anti-Fingerprinting feature can hide information that certain websites need to function. If you encounter problems with a website you normally visit while Anti-Fingerprinting is enabled, you can temporarily disable the feature via the Security and Privacy Center.

What is Anti-Phishing?

Anti-Phishing blocks malicious websites and phishing attempts while you browse the web. It also prevents you from downloading potentially malicious content from the web, which may try to infect your Mac. Anti-Phishing is enabled by default.

To disable this feature, go to the Security & Privacy Center and click the slider on the Anti-Phishing tile so that it changes from green (ON) to gray (OFF).

What is Anti-Tracking?

The Anti-Tracking feature protects your privacy by preventing websites, analytics companies, advertising networks, and other web services from tracking your online activity. It also uses filters to completely remove web bugs, tracking scripts, and other information collectors from the sites you visit. Anti-Tracking is enabled by default.

To disable this feature, go to the Security & Privacy Center and click the slider on the Anti-Tracking tile so that it changes from green(ON) to gray (OFF).

What is Stealth Mode?

To open a web page in Stealth Mode, go to the Security & Privacy Center and click Launch Window on the Stealth Mode tile.

What is Extension Guard?

Extension Guard prevents untrusted extensions (also known as add-ons and plug-ins) from being installed in Avast Secure Browser. This feature is enabled by default.

What is Privacy Cleaner?

To use Privacy Cleaner to clear your history, go to the Security & Privacy Center and click Launch Cleaner on the Privacy Cleaner tile.

What is Flash Blocker?

Flash-based content opens your Mac to security vulnerabilities, takes up space, and can use a large percentage of your Mac's battery life. The Flash Blocker feature blocks Flash-based content from running on your Mac, unless you choose to allow it.

To disable this feature, go to the Security & Privacy Center and click the slider on the Flash Blocker tile so that it changes from green (ON) to gray (OFF).

What is Webcam Guard?
