Windows 10: W11 defender deleting .exe files for steam games

Hi,today I noticed Windows defender deleted some of my games from steam.That is obviously extremely unwanted action from the Windows. It should not delete anything without me saying so.When I go into "history", all my games that are not working, are there. Threat "SERIOUS". There is no button like "restore" or "ignore this program" or "add exception to this folder" or whatever.When I redownload the files from steam, windows immediately deletes them again.How do I stop the defender from doing this?

:)

 

Windows Defender Deleted My Steam and games

Similar issue with a clean install of Win10 Home with 1703 update. When I was downloading my games from Steam, Defender said that one of the .exe files was a Trojan: Win32:Trojan-gen

I uninstalled the game inside the Steam client and downloaded it again with no issues from Defender...very strange behavior.

 

Windows Defender Deleted My Steam and games

I don't know why but Window defender decided to think that my Steam is a virus and removed it, I can not launch the app or any games, it says that Steam might be containing virus at first and now it says cant find it since it's deleted, this is frustrating
since i have a lot of games installed and I have to install everything again.

Hi Sam,

There are several reasons why you are unable to play the game that you installed using the Steam Client. It is possible that the app is corrupted or the permission settings are not enabled on your PC. To resolve your concern, we suggest that you reset the
app.

This process can help restore corrupted game installation files. Here's how:

• Press the Windows key on your keyboard, and then click the Settings icon.
  
• Select System, and then select Apps & features.
  
• Find the game, and then click on Advanced options.
  
• Click Reset.
• Restart your computer for the changes to take effect.

You may visit this
link for the instructions on how to enable app permissions on your PC.

Make sure that you are using an administrator account to launch the app. If you are still experiencing the same issue, remove the
ClientRegistry.blob file by following the steps below:

• Close the Steam Client and go to the Steam root folder or C:\Program Files (x86)\Steam.
• Look for the ClientRegistry.blob file.
• Make a copy of the file and change it to a different file name. (for example, copy.ClientRegistry.blog)
• Delete the original file.
• Launch the Steam Client and run your game again.

If the issue persists, you may relocate the Steam Client by performing the steps below:

• Close the Steam Client app and go to the Steam installation folder.
• Browse for the installation files that you would like to move.
• Delete all of the files inside that folder except the SteamApps & Userdata and Steam.exe.
• You may cut and paste the whole Steam installation folder to a default storage location on your PC.
• Launch the app again and make sure to log in using your account.

After signing in, you'll need to change the default installation path for the games that you will install in the future. Here's how:

• Launch the Steam Client and go to the Settings
  menu.Select Steam Library Folders from the
  Downloads tab.
• You may create a new path by selecting Add Library Folder. All future installations will go directly to the newly created path.
• Right-click on the newly created path and make sure that it is set to default.

If you are still unable to play your games using the Steam Client, we recommend that you contact
Steam Support directly for additional solutions in fixing the app and its components.

Should you have any other queries, you can contact us anytime.
