Whatever the case may be, it’s best to take precautionary measures and review your device’s privacy settings to stop your favorite software from spying on you.

Furthermore, many people often complain of getting a black screen error when they try to launch the Avast antivirus app. In addition, other error messages like “Avast Antivirus not updating” and “Avast doesn’t trust the installer” also compromises the app’s performance.

While many error messages could be easily resolved, some issues are persistent and become a regular source of frustration for the users.

If you are also struggling with the same issues, you can either troubleshoot these issues or say goodbye to the Avast Free Antivirus software.
