Analyzing performance issues (Windows)

This Article Applies to:

  • Avast Business Hub
  • Avast Business On-Premise Console
  • Avast Business Antivirus
  • Small Office Protection

You can use this process to help troubleshoot performance issues, such as programs running slowly, on devices running Avast products (Windows 8 and above).

You will need to download and install Windows ADK on your device. Windows ADK is usually not installed on a server OS, while workstation OSes such as Windows 8 or 10 should have it installed.

During installation, ensure that only the “Windows Performance Toolkit” feature (highlighted below) is checked. You do not need any other features for this process.

You can determine which set of instructions to use below by navigating to C:\ProgramData\Avast Software\Avast\ and looking for the file profile.wprp. If you have the file, use the first set of instructions. If you do not, use the second set.
