Have you tried to install an older version of Avast Antivirus on to your new Windows 10 computer? I am sure that not only one user has encountered some serious issues with the Avast application in Windows 10  and the most disturbing of them being the fact that Avast does not recognize the Windows system files as part of the operating system and thus trying to delete some of them. You can read the lines below for a detailed explanation about how to fix your Avast in Windows 10 and what is the latest version you should install.
Fix Windows 10 compatibility issues with Avast Antivirus

Avast is one of the most popular antivirus programs out there, and a lot of users who were using Avast in previous versions of Windows installed it on Windows 10, as well (some of them change their mind and switched to Windows Defender, but that’s a story for another day). But even if Avast Antivirus is fully-compatible with Windows 10, some errors may still occur. So, we included all reported issues we could find and solutions for them in this article, and if you’re facing some of them, hopefully the following solutions will be helpful.

How to fix Avast Antivirus Problems in Windows 10

Case 1 – Windows 10 Action Center Doesn’t Recognize Avast

One of the most frequent issues with Avast in not just Windows 10 is when Windows Action Center Doesn’t recognize Avast. If that happens, you’ll probably receive pop-up messages in the down right side of your screen saying something like “Windows Defender and Avast Antivirus are both turned off,’ or ‘Windows did not find an antivirus program”. Fortunately there’s an easy solution for this, you just need to follow the steps below.

First thing we’re going to try is disabling Avast Antivirus and than re-enabling it again, in order to make Windows 10 recognize it:

  1. Right-click on Avast icon in your taskbar
  2. Go to Shields control and choose Disable for 10 minutes avast windows 10
  3. After that, enable it again the same way, and selecting Enable all shields

This should make Windows 10 recognize Avast, and above-mentioned messages shouldn’t bother you anymore. But if the issue is still present, you have one more option to try. Here’s exactly what you need to do:

  1. Right-click on the Start Menu and choose Command Prompt (Admin)
  2. In the Command Prompt type ‘winmgmt /verifyrepository’ and press Enter. avast antivirus windows 10
  3. If you get ‘WMI repository is consistent -no problems detected,’ type ‘winmgmt /resetrepository’ and press Enter.
  4. If you get ‘WMI repository is inconsistent -problems detected,’ type ‘winmgmt /salvagerepository’ and press Enter.
  5. If you get ‘WMI repository has been salvaged – WMI repository has been successfully rebuilt,’  continue to the last step.
  6. Now reset your computer

Case 2 – Avast Causes Black Screen in Windows 10

Some users also reported that installing Avast on Windows 10 caused a black screen on their displays. This is not a common issue, but if you experienced it, you can try the following solution:

  1. Click on Avast icon in the taskbar and open Avast user interface
  2. Go to Settings tab, and then to Active Protection
  3. Click on Customize, next to File system Shield avast win 10
  4. Go to Exclusions tab, click add and add the following address to exclusions:
    • C:\Windows\Explorer.exe,’ and ‘C:\Windows\ImmersiveControlPanel\SystemSettings.exe
  5. Restart your computer

After that, you shouldn’t face the black screen issue anymore. But if you do, maybe the problem is not related to Avast, so I recommend you to check our article about solving the screen problems in Windows 10, for further solutions.

This error message sometimes appears when you’re trying to install Avast on Windows 10. Namely, you’ll get ‘Process Trust’ fatal error pop-up message saying ‘Avast doesn’t trust Avast Installer,’ which means that you cannot install Avast on your computer. This error appears due to a conflict between avast and your currently installed antivirus program.

This error will remind you that having two antivirus programs installed on your computer is not a good thing.
