Silent mode lets users disable notifications, alerts, and pop-up windows. This allows users to conduct virus scanning and other tasks without interruption. This is especially beneficial for gamers, who want to concentrate on their game, not being distracted by the antivirus’s notifications.
The Avast silent mode is accessible through the settings menu, and it can be enabled or disabled depending on the need. Silent mode disables all notifications not deemed vital or relevant to a critical security issue once it is activated. This includes notifications regarding updates to security scan results and other notifications that would normally be displayed on screen. This mode is able to turn on notifications for notifications related to games or full-screen apps.
If the silent mode has been removed, all announcements, including incoming emails and Windows content, are renewed. This may decrease the speed of your avast since the antivirus software must perform more background tasks such as scanning and updating it. This isn’t a huge issue, but could cause some users to become annoyed.
In addition to the silent mode, Avast also has a noiseless gaming mode that can be disabled or enabled depending on the need. This feature is accessible through the settings menu. It is designed to allow gamers to concentrate on their game without being distracted by Avast’s notifications, alerts or pop-up windows. This feature is especially beneficial for people who use their computer for tasks that require a lot of resources like video gaming or programming.
