Risk impact

Avast Online Security & Privacy requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install Avast Online Security & Privacy 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

Avast Online Security & Privacy has earned a good reputation and can be trusted.

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. 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 a Chrome extension, especially ones with higher risk impact and/or higher risk likelihood.

É leve e funcional, indica o nível de segurança do sites. Só a função de anti-rastreamento que faz parte da versão Pramium, por isso há outras extensões que a tem gratuitamente.

If figured out Avast is tracking and selling data to advertisers. I have uBlock Origin installed and I was randomly getting a popup warning about advertising tracking no matter what site I'm on. At first I didn't know what was causing it. When I disable the Avast extension this it warning stops.

The manifest file declares the requirements and permissions that a Chrome extension will have access to. By reviewing the manifest, you may be able to determine if a Chrome extension is over-reaching (for example, if an extension is overriding your new tab page, or search provider, or requesting access to your web activities without any good reason).
