How to Troubleshoot and Fix Common Avast Antivirus Errors

Avast Antivirus is a popular and widely-used security software, but like any program, it can sometimes encounter errors or issues that prevent it from functioning properly. In this comprehensive guide, we’ll explore some of the most common Avast errors and provide step-by-step instructions on how to troubleshoot and fix them.

The Base Filtering Engine (BFE) Service is Not Running

One of the most common Avast errors is the “The Base Filtering Engine (BFE) service is not running” error. This issue can occur during the installation process or when trying to launch Avast Antivirus. The BFE service is essential for the proper functioning of the Windows Filtering Platform, which is required for Avast’s firewall to operate correctly.

To resolve this problem, you’ll need to ensure that the BFE service is running. Here’s how to do it:

1. Press the Windows key R to open the Run dialog, then type “services.msc” and press Enter to open the Services console.
2. Locate the “Base Filtering Engine” service in the list, and check the “Status” column. If the status is not “Running,” right-click on the service and select “Start” to start it.
3. If the BFE service still doesn’t start, you may need to repair it using the Windows Firewall Diagnostics tool or remove any malware that may be blocking the service by using the Avast Rescue Disk.
4. Once the BFE service is running, you can retry the Avast installation or launch the program.

Avast User Interface Fails to Load

Another common Avast error is when the user interface (UI) fails to load. This can happen for a variety of reasons, such as conflicts with other software or issues with the Avast service.

To troubleshoot this issue, follow these steps:

1. Open the Services console (services.msc) and locate the “Avast Cleanup” service. Right-click on it and select “Properties.”
2. In the “Avast Cleanup Properties” window, ensure that the “Startup type” is set to “Automatic” and that the service is running. If not, start the service and apply the changes.
3. If the issue persists, try restarting your computer to see if that resolves the problem.

Avast Business Console Installation Issues

For users of the Avast Business Console, there can be various installation-related issues. These can include problems with installing new updates or the inability to open the console altogether.

To troubleshoot Avast Business Console installation problems, try the following steps:

1. Run a repair installation of the Avast Business Console.
2. Remove, reboot, and then reinstall the Avast Business Console.
3. Stop the Avast Business Management Console service, then navigate to the config folder and delete the contents.
4. Restart the Avast Business Management Console service and try to install the new update or open the console again.

Remember, these are just a few of the most common Avast errors and their solutions. If you encounter any other issues with Avast Antivirus, it’s always a good idea to check the Avast support website or reach out to their customer support team for further assistance.
