Trend keeps disabling my game (Fallout New Vegas) by deleting a single file

How can I stop Trend from deleting game files? I have already set up exemptions for the entire directory yet Trend has found a way to disable my game. In order to play the game I have to first shut down Trend then verify the game files (in Steam) which restores the missing file then re-enable Trend. I would like to simply whitelist the misidentified file but I can't figure out what file is being targeted. Is there a log somewhere?

I put the whole Steam folder in my exception list.

 Hello,


It sounds like Trend Micro Maximum Security is flagging a file from Fallout: New Vegas as a "false positive." This often happens with older games or specific mods (like NVSE) that use "DLL injection" to work.
To fix this, you need to restore the file and then add it to the Exception List so Trend Micro ignores it in the future.  

Step 1: Restore the deleted file
If the file is already gone, it is likely in Trend Micro's "Quarantine."

1. Open the Trend Micro main console.
2. Click the Security Report icon (it looks like a small chart or document).
3. Click on Security Threats.
4. Find the file related to Fallout: New Vegas in the list.
5. Select the file and click Restore.
6. Click Yes when the warning appears.

Step 2: Add the file to the Exception List
Once the file is back, you must tell Trend Micro to stop scanning it, or it will just delete it again.

1. On the Trend Micro main console, click the Settings icon (the gear).  
2. Go to Exception Lists in the left-hand menu.
3. Click Programs/Folders.
4. Click the + Add button.
5. Click Browse and navigate to your Fallout: New Vegas installation folder.  
   • Default Path: C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas
6. Select the specific file that was being deleted (or select the entire game folder to be safe) and click Open.  
7. Click Apply, then OK.

Step 3: Verify the game files (if needed)
If the file didn't appear in the Quarantine list or the game still won't launch, Steam can replace the missing file for you:

1. Open Steam and go to your Library.
2. Right-click Fallout: New Vegas and select Properties.
3. Go to the Installed Files (or Local Files) tab.
4. Click Verify integrity of game files.

[!TIP] Why is this happening? Many Fallout: New Vegas mods (like the Script Extender) use techniques that look suspicious to modern antivirus software even though they are safe. If you are using mods, it is highly recommended to add the entire game folder to the Exception List.
