Troubleshooting Features in Local Client

This Article Applies to:

  • Avast Small Business Solutions
  • Avast Small Office Protection


Multiple troubleshooting features are available for the Avast local client. To access them, click Menu in the top right corner of the Essential/Premium/Ultimate Business Security or Small Office Protection UI, then go to Settings > General > Troubleshooting.

Regardless of whether your local client is managed by an Avast Business Management Console or not, the following troubleshooting options will be available in the UI:

  • Enable Offline Mode — Disconnects the device from the internet. Note that this setting depends on Firewall - if Firewall is uninstalled or disabled, Offline Mode will not be available.
  • Enable Passive Mode — Disables the AvastAntivirus to allow functioning alongside some other antivirus software. To learn more, see Passive Mode.
  • Enable Self-Defence — This feature should not be disabled unless absolutely necessary (e.g. during some troubleshooting steps), as Self-Defense protects the device from unwanted actions. The feature should then be re-enabled once the needed actions are performed.
  • Block vulnerable kernel drivers — Blocks exploitable drivers from loading into OS kernel memory and alerts the user. This feature should not be disabled unless troubleshooting.
  • Enable hardware-assisted virtualization — The main purpose of disabling this feature is for troubleshooting purposes (for example, when encountering an issue with virtual machines). The feature should be re-enabled once the needed actions are perfomed (a restart is required to enable/disable).
  • Delay Avast startup — This feature is used to delay the startup of the Antivirus services. The feature should be disabled once the needed actions are performed, as it leaves the device unprotected during startup.
  • LSA protection — Protects from unauthorized access to the Local Security Authority process, which stores and manages user processes (can potentially cause problems with some third-party single sign-on apps).
  • Repair app — Runs a repair on the local client. See Repairing Antivirus for more information on this and other repair options.
  • Record a performance problem (should be used only if requested by Avast Support) — Records a performance problem directly inside the Antivirus client. See Recording Performance Problems for instructions.
  • Enable debug logging — Gathers a large amount of information and system logs to help find problems (a restart might be required to fully enable debug logging). See Enabling Debug Logging for Antivirus for more information.
  • Send logs — This feature is the built-in Support tool. You can select Send logs to open the tool and send the output to Avast support directly. See Creating and Sending Support Packages for further instructions.

If your local client is managed by the Hub, you can enable most of these features via Policy settings of the console as well (see Troubleshooting Features in Business Hub).


Some features are only available in the unmanaged version of the local client. These are:

  • Add/Modify Components (under Still having problems?) — Allows you to add or remove shields and other components

  • Back up your Avast settings — Allows you to back up and restore settings from the client (*.avastconfig file type)

  • Reset all settings — Resets the client settings to Avast default values

Additional Troubleshooting Features

In the Protection section of the client UI, you can also enable Anti-Rootkit Shield and Anti-Exploit Shield. For more information, see Core Shields Settings.
