Windows 10: Failure to launch avast Antivirus after upgrade to windows 10

Today l upgraded my windows laptop to windows 10 pro but ever since after the installation. When l try to open avast Antivirus on the desktop it fails to launch it's like the performance of the app has been blocked because before I did upgrade it was working perfectly fine. Anyone to tell me what is wrong.

:)

 

Do Avast Free Antivirus compatible with Windows 10 Pro?

That's a question for
Avast Support, but see:
Will Avast be compatible with Windows 10?

In short, ensuring that Avast is compatible with Windows 10 is quite simple. Avast version V2015 R2 and newer are already compatible with Windows 10. Users who currently have V2015 R2 or newer installed and plan to update from Windows 7 or 8 to Windows 10
will automatically have Avast transferred to Windows 10 at the same time.

For users currently using older versions of Avast, it's highly recommended to update your Avast product
prior to updating to Windows 10 to ensure an easy, hassle-free transition.

Compatibility report for Windows 10: FAQ

- Microsoft Windows 10 (Important notes section) Specifications page:

Many applications, files, and settings will migrate as part of the upgrade. However, some applications or settings may not migrate.-

• For antimalware applications, Windows will check to see if your antimalware subscription is current (not expired) and compatible during the upgrade.
• If the antimalware application is compatible and current, your application will be preserved during the upgrade to Windows 10.
• If the antimalware application is incompatible, Windows will uninstall your application while preserving your settings. After upgrade is complete, if your antimalware provider has informed Microsoft that it has made a compatible version available for your
  active subscription, Windows will notify you to install the latest version available with the settings that were set prior to upgrade.
• If your antimalware subscription is not current (expired),
  Windows will uninstall your application and enable Windows Defender.

Also:

• Some applications that came from your OEM may be removed prior to the upgrade.
• For certain third party applications, the 'Get Windows 10 app' will scan for application compatibility. If there is a known issue that will prevent the upgrade, you will be notified of the list of applications with known issues. You can choose to accept
  and the applications will be removed from the system prior to the upgrade. Please be sure to copy the list before you accept the removal of the application.

Would finally suggest not to rush into Win10 immediately. Hope this helps.

 

Avast Antivirus

I had exactly the same problem and AVAST antivirus was the cause.

Once AVAST was uninstalled, Windows 10 worked great.

now I need to determine which antivirus is best for Windows 10!

; Avast does not show in the list of apps. I searched for it on my PC and found it on one of the drives. I tried to delete it, but the message still comes up, and therefore my Windows update cannot be completed. How do I get rid of Avast Antivirus?
