Purpose

The traffic between your browser and a web server, including sensitive data, is readable if you fail to establish a secure connection first.

Website ads and content, including legitimate ones, can be compromised (or injected) with malicious code that puts your system at risk of infection.

Audience

Initial considerations

Some webpage functionality can be impacted through the use of an ad-blocker. If you encounter issues on a page you need to access and trust, try pausing the ad-blocker or granting an exception for the page, rather than disabling the blocker.

Ensure your system is protected from viruses and malware.

While ad-blocking software can help proactively stop malicious content from being loaded, it is important that your system is further protected, should anything be missed or if you need to pause your ad-blocker.
