Risk impact

McAfee® Web Boost requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install McAfee® Web Boost if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

McAfee® Web Boost has earned a good reputation and can be trusted.

Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing an Edge add-on, especially ones with higher risk impact and/or higher risk likelihood.

Only works correctly when it wants too. On various different websites videos play even though I have it set with access to all websites. It's frustrating because I have to pause the videos and sometimes multiple vids on single site.

Web Boost installed automatically. It also prevented iHeart radio from playing, even when I selected the play button for audio! I turned off web boost and now I can listen to music again! I hope turning it off doesn't create other problems as I am not very computer savvy.
