Avast app not working? – How to Fix

Avast is a renowned antivirus software that has been protecting millions of devices worldwide.

However, there are instances where users might encounter issues with Avast not working properly.

This could be due to various reasons such as outdated software, corrupt installations, or conflicts with other programs.

In this article, we aim to provide comprehensive solutions to address the issue of Avast not working, ensuring that your device remains protected from malicious software and threats.

Common Causes of Avast Not Working

Outdated Software

One of the most common reasons for Avast not working is outdated software.

Like any other software, Avast requires regular updates to ensure it has the latest virus definitions and is capable of combating new threats.

If you have not updated Avast in a while, it may not function properly or provide adequate protection.

To resolve this, check for updates in the Avast user interface and install any available updates.

Corrupt Installation

Another possible cause for Avast not working is a corrupt installation.

This can happen if the installation process was interrupted or if there were issues with the installation files.

In this case, you may need to uninstall Avast completely and then reinstall it to ensure that all components are installed correctly.

Conflicts with Other Software

Avast may also conflict with other software installed on your device, leading to issues with its functionality.

This is commonly seen with other antivirus programs or security tools.

It is generally recommended to have only one antivirus program installed at a time to prevent such conflicts.

If you have other antivirus software installed, consider uninstalling them and see if this resolves the issue with Avast.

Steps to Resolve Avast Not Working

Checking for Updates

Ensure that your Avast software is up to date by opening the Avast user interface and navigating to the ‘Update’ section.

Here, you can check for both program and virus definition updates. Installing these updates can resolve any compatibility issues and ensure that Avast is functioning correctly.

Reinstalling Avast

If updating Avast does not resolve the issue, the next step would be to reinstall the software.

First, you will need to uninstall Avast using the ‘Add/Remove Programs’ feature in Windows, or by using Avast’s own uninstallation tool.

Once uninstalled, download the latest version of Avast from the official website and proceed with the installation process.

Resolving Software Conflicts

Identify any other antivirus or security software installed on your device and consider uninstalling them.

Having multiple antivirus programs can lead to conflicts, resulting in none of them working correctly.

After uninstalling other security software, restart your device and check if Avast is now working as expected.

Additional Tips for Ensuring Avast Functions Properly

Regularly Update Your Operating System

Ensuring that your operating system is up to date is crucial for the proper functioning of Avast and other software.

Updates often include security patches and improvements that can enhance the compatibility and performance of Avast.

Avoid Using Cracked Versions of Avast

Using cracked or pirated versions of Avast can lead to numerous issues, including the software not working correctly.

These versions may be tampered with and could compromise the security of your device.

Always ensure that you are using a legitimate version of Avast, purchased or downloaded from the official website.

Contacting Avast Support

If you have tried all the above solutions and Avast is still not working, it may be time to contact Avast support.

They can provide expert assistance and help resolve any issues you may be facing.

Provide them with as much information as possible about the issue and any steps you have already taken to try and resolve it.


Encountering issues with Avast not working can be frustrating, but it is usually resolvable with some troubleshooting.

Ensuring that the software is up to date, reinstalling it, and resolving any software conflicts can help get Avast back up and running.

Remember to keep your operating system updated, avoid using cracked versions of the software, and do not hesitate to contact Avast support for assistance.

By following these steps, you can ensure that your device remains protected by Avast, and any issues with the software not working are swiftly resolved.
