This Group Containers folder stores shared app data used by Avast Security or Avast Premium Security for Mac features and background components.
What is 6H4HRTU5E3.group.com.avast.osx?
This folder is part of Avast Security or Avast Premium Security on macOS. A Group Containers directory lets an app and its helper components share the same data, which can include settings, security status information, support files, and other working data needed across the Avast interface and background protection features. Users typically encounter it when reviewing storage, troubleshooting app behavior, or cleaning up files left behind after uninstalling security software. Because antivirus tools rely on coordinated background components, shared container data can be important for notifications, scans, and real-time protection workflows. On a Mac that still uses Avast, this folder belongs to the product's normal operation rather than to personal documents.

Safety overview
Status: Mostly safe
The folder is associated with Avast Security for Mac, a security product that uses background protection features and may request permissions such as Full Disk Access, login items, and security extensions to work correctly. Those permissions are consistent with antivirus software, but removing this shared container while Avast is still installed can interrupt scans, alerts, updates, or stored settings. If you no longer use Avast, leftover data in this location is usually not harmful, but it may contain logs, configuration details, or other product data you may want to remove only after uninstalling Avast fully.
Recommendation: Keep this folder if Avast Security or Avast Premium Security is still installed or you still rely on its protection features. If Avast has already been uninstalled and you do not plan to reinstall it, you can remove this folder as part of cleanup. If you are unsure whether Avast is still active, open Login Items and installed applications first so you do not break an antivirus setup that is still in use.
