Fix: Avast Service Not Responding

Is Avast Service not responding for some reason on Windows 10 or Windows 11? Here's everything you need to know and how to fix the issue.

Avast is an antivirus program that is often updated by the development team. However, along with all the improvements, optimization, and bug fixes, these updates sometimes bring unexpected issues.

The Problem Explained

When you experience the Avast Service Not Responding issue on Windows 10, there might be a few different reasons for the cause:

  • The Recent Avast Update Is Unstable
  • A Recent Windows Update Conflicted With Avast’s Services & Settings
  • Corrupted Files Within Your Avast Root Folder (Main Installation Location / Folder)
  • You’re Running The Latest Version of Avast On An Outdated Windows Version

Most of the time, the issue occurs because of the shaky Avast update, but even though it doesn’t seem logical, it can be fixed without going back to a previous version.

The methods listed in the guide below are easy to follow and don’t require any previous computer knowledge, yet can solve this issue and ensure you keep using your PC while protected by the Avast antivirus program.

Fix 1: Update Your Operating System To The Latest Version

Microsoft recommends updating your Windows to the latest version whenever a new update is available. However, their updates are also not entirely stable all the time, which is one of the main reasons why users often postpone them. Windows is a seriously complex software, after all.

But, when it comes to fixing this issue, updating your Windows to the latest version is something you have to do, like it or not. It often happens that the latest Avast version is optimized for the latest Windows version, which is why you may be experiencing inconveniences right after updating the antivirus app, despite everything working perfectly previously for a long time.

If you have trouble updating Windows, we have a helpful guide covering multiple useful methods to get the updates rolling as intended.  

Fix 2: Restart The Avast Services

Avast seems to experience problems when updating while it has been previously running on your system. It doesn’t make much sense, but it has something to do with the services.

Usually, restarting the Avast services helps get things back to normal. Here’s how to do it:

  1. Press Windows + R on your keyboard to open the Run function.
  2. Type in services.msc and press Enter on your keyboard.
  3. On the list that shows, locate the Avast antivirus service and right-click on it, then choose Properties.
  4. A window will open, and near the bottom, you can see a section where the current service status is displayed. It should say “Running”. Click the Stop button right below it, then wait a few moments for it to stop.
  5. After the service is fully stopped, the button will then change, and it will say “Start.” Click on it to start the service once again.
  6. To save these changes, click on Apply and then OK at the bottom of the window.

This method doesn’t require you to reboot your PC, but we recommend doing it either way. This will ensure the changes take effect, and you should then be able to start Avast again and run it smoothly without further issues.   

Fix 3: Use The Avast Repair Utility

If you are experiencing the Avast Not Responding problem, one of the ways you can fix it is by using the Repair Utility.

Here’s how to do that:

  1. Open Avast on your PC, but make sure to start it while granting Administrator Privileges. You can do this by right-clicking the icon and choosing Run as Administrator.
  2. Click Menu, then Settings to open the configuration panel. From here, open the Settings tab and choose General.
  3. Click the Troubleshooting button and choose Repair App to begin the process.
  4. Wait until the procedure is complete. The time it takes for this to finish will depend on your system’s performance. It’s best just to wait it out.

After finishing the process, restart your computer and rerun Avast. Remember to execute it with administrative privileges as well.

It should now start and continue working without further complications. This method helped a lot of users, and it should help you as well.

Attention: This technique can assist you to activate Avast and it doesn’t crash immediately. If it crashes right from the beginning, consider reviewing Fix #2 and #1 instead.
