Analyzing Performance Issues on Windows

Analyzing issues

In cases where some AVG processes are consuming more CPU and/or memory than expected, you may need to gather performance analysis data to provide to Business Technical Support.

Before gathering performance analysis outputs, we suggest you verify the following on the affected system(s):

• No other antivirus applications are running alongside your AVG Antivirus
  • Running multiple antivirus applications at once will lead to performance issues and, in some cases, BSOD/system crash
• Operating system is up-to-date
• AVG application is up-to-date
• Scheduled or manually initiated Antivirus scans are not currently running, and are preferably scheduled to scan outside of normal working hours
• Any required vendor-suggested exclusions are in place for other applications running on the system

At this point, try to confirm exactly which AVG process is using more CPU/memory, and whether it’s a specific application or a set of applications that run slowly. Also check if the issue can be induced easily or not.

Troubleshooting

The steps here are intended to determine what is causing the issue, rather than providing a permanent fix.

1. Disable all non-AVG and non-Microsoft applications from MSConfig and reboot the system. Then verify if there is any change in behavior, as another application could be causing the issue
2. Open the AVG Business client and check if disabling any specific component or feature will resolve the issue
3. Uninstall components from the policy (if managed) or locally from the device (if unmanaged)
4. Reboot the system
5. Verify if the issue is resolved

Performance analysis

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

If you do not already have it on your device, you will need to download and install Windows ADK. 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.

If you installed AVG on a non-default location, please alter the commands where necessary to use the proper location for your AVG files.

1. Download the configuration file to a local folder
2. Launch Command Prompt as an Administrator
3. Navigate to the folder with the downloaded configuration file (avast-profile.wprp)
4. Enter command to start recording: wpr.exe -start avast-profile.wprp
   • If you saved avast-profile as an .xml file, the command would be: wpr.exe -start avast-profile.xml"
5. Reproduce the performance issue, waiting at least a minute or two to gather data
6. Enter command to stop recording: wpr -stop avast-log.etl
7. Zip the file avast-log.etl and share it with Business Support via the AVG FTP server (see Uploading Files to AVG FTP Server)

This procedure will not collect any documents or personal information from your device. It records all running process activities to help locate the source of the performance issue.
