How to Remove Avast From My Computer Completely
Avast Antivirus can be useful for protecting your computer from malware and other online threats, but there may be situations where you want to uninstall it. You might be switching to another antivirus program, troubleshooting a Windows problem, or simply no longer want Avast installed on your computer.
Removing an antivirus program is slightly different from uninstalling an ordinary application because security software can install services, drivers, background processes, and other components. Simply deleting the Avast folder is not recommended because it can leave behind unwanted files or cause Windows to behave unexpectedly.
In this guide, you will learn how to remove Avast from your computer completely.
How to Remove Avast From My Computer Completely
To remove Avast from your computer completely, first close Avast and uninstall it through Windows Settings > Apps > Installed apps. Restart the computer when Windows asks you to do so. If Avast remains installed or you encounter an uninstall error, use the official Avast Uninstall Utility, commonly called Avast Clear, to remove the remaining Avast components. After restarting Windows, check the installed apps and Program Files folders to confirm that Avast has been removed.
The easiest approach is to start with Windows’ normal uninstall feature.
If that does not work, you can move to Avast’s dedicated removal tool.
Step 1: Check Whether Another Antivirus Is Ready
Before removing Avast, think about what will protect your computer afterward. If Avast is your only antivirus program, uninstalling it can leave your computer without third-party antivirus protection until another security solution is active.
On modern versions of Windows, Microsoft Defender Antivirus is generally available as part of Windows Security and can provide antivirus protection when another compatible antivirus product is not active.
If you are removing Avast because you are installing another antivirus program, have the replacement installer ready before starting the removal process. You do not necessarily need to install it first, but having it available makes the transition easier.
Step 2: Close Avast Before Uninstalling It
Before starting the uninstall process, close any Avast windows that are currently open. Look at the notification area on the right side of the Windows taskbar, near the clock. If you see an Avast icon, right-click it and look for an option to exit or close the application.
You may not see an exit option depending on your Avast version and its security settings. That is normal. Windows can usually terminate the necessary Avast processes when you start the uninstall process.
Do not manually delete Avast’s installation folders at this point. The proper uninstaller needs to remove the program and its associated components correctly.
Step 3: Open Windows Settings
Now open Windows Settings. On Windows 11, right-click the Start button and select Settings. You can also press Windows + I on your keyboard.
When Settings opens, select Apps from the left side of the window. Then select Installed apps.
On some versions of Windows, the page may be labeled slightly differently. The important thing is to find the list containing the applications installed on your computer.
Step 4: Find Avast in the Installed Apps List
The Installed apps page displays the programs currently installed on your computer. Scroll through the list until you find Avast Antivirus or the particular Avast product you installed.
If there are many applications, use the search box at the top of the page. Type Avast into the search box. Windows should filter the list and display matching Avast applications.
You may see more than one Avast-related entry. For example, Avast may have installed additional components alongside the main antivirus application. Start by selecting the primary Avast antivirus application.
Step 5: Start the Avast Uninstall Process
Once you find Avast, click the three-dot menu next to its name and select Uninstall. Windows may display another confirmation asking whether you want to remove the application.
Select Uninstall again if prompted.
An Avast setup or maintenance window should appear. Depending on the version of Avast installed on your computer, the wording and appearance can be different. Look for the option that allows you to uninstall or remove Avast rather than repair or modify it.
Follow the instructions shown on the screen. You may be asked to confirm that you want to remove Avast and wait while Windows deletes its components.
Step 6: Allow Avast to Complete the Uninstallation
The removal process can take several minutes. Do not turn off your computer while the uninstaller is working.
You may see Windows security notifications or Avast-related messages during this process. Read them carefully and continue with the uninstall option if you are certain that you want to remove Avast.
At the end of the process, Avast may ask you to restart your computer. Restarting is important because some antivirus components operate as Windows services or drivers and cannot be completely removed until Windows shuts down and starts again.
Save your work in other applications and choose the restart option when appropriate.
Step 7: Restart Your Computer
After Avast finishes uninstalling, restart Windows even if you are not specifically required to do so.
Click Start, select the Power button, and choose Restart. Windows will close your running applications and load the operating system again.
Restarting gives Windows an opportunity to unload Avast services and remove components that were still being used during the uninstall process.
Once you reach the Windows desktop again, wait for the system to finish loading before checking whether Avast has been removed.
Step 8: Check Whether Avast Has Been Removed
After restarting, open Settings > Apps > Installed apps again and search for Avast.
If the main Avast antivirus application is no longer listed, the normal uninstall process has probably completed successfully.
You can also check the notification area near the Windows clock. If the Avast icon is gone, that is another indication that the application has been removed.
Do not assume that every Avast-related file needs to disappear from your computer. Some files can remain as harmless remnants, temporary files, logs, or folders associated with other Avast products. The important thing is that the antivirus itself and its active services have been removed.
Step 9: Use Avast Clear If Normal Uninstallation Fails
If Windows cannot uninstall Avast, the uninstall process repeatedly fails, or Avast continues appearing as an installed application after restarting, use Avast’s dedicated Avast Clear removal utility.
Download the utility only from the official Avast website rather than from an unknown third-party download site. Avast Clear is specifically designed for situations where the standard Windows uninstall process cannot remove Avast properly.
After downloading the utility, follow its instructions. It may recommend running the removal process in Windows Safe Mode, because Safe Mode starts Windows with a limited set of drivers and services.
If Avast Clear asks you to restart into Safe Mode, follow the instructions displayed by the utility. Select the appropriate Avast installation if the tool asks you to identify the product, then start the removal process.
Step 10: Restart Windows After Using Avast Clear
When Avast Clear finishes removing the Avast components, restart your computer normally.
This final restart is important because the removal utility may have deleted services, drivers, registry entries, and other components that Windows could not safely remove while Avast was running normally.
After Windows starts, check Settings > Apps > Installed apps and search for Avast one more time.
If Avast no longer appears and you do not see its active processes or notifications, the removal should be complete.
Step 11: Check Windows Security
Finally, open Windows Security by searching for it from the Start menu.
Look at Virus & threat protection and check the protection status displayed by Windows. If you have installed another antivirus program, Windows may recognize that security software instead.
If no third-party antivirus is installed, Windows may activate Microsoft Defender Antivirus automatically. Make sure Windows Security does not show an important protection problem before continuing to use the computer normally.
Faqs
Can I remove Avast from Windows 11 using Settings?
Yes. You can normally remove Avast through Settings > Apps > Installed apps. Find Avast, open its three-dot menu, select Uninstall, and follow the Avast removal instructions.
Why won’t Avast uninstall from my computer?
Avast may fail to uninstall because a process is still running, Windows permissions are interfering with the removal, or the installation has become corrupted. In that situation, Avast Clear can be used to perform a more thorough removal.
