Problem with Lightroom 13.4


I am currently using F-Secure Internet Security (19.5) and unfortunately I have a problem with Lightroom( 14.4). Unfortunately, Lightroom keeps crashing. I can't explain the reasons. If I uninstall f-secure, Lightroom runs stably. Does anyone have any ideas about this?

    Hello @Bergischer_Löwe

    We welcome you to our forum and thank you for your post.

    In the situation you describe, we recommend that you first check whether the program is blocked by DeepGuard.

    To allow an application that DeepGuard has blocked:

    1. Open the program
    2. Go to Viruses & Threats
    3. Select Settings
    4. Navigate to DeepGuard
    5. Select View Blocked applications
    6. Select the blocked application that you want to allow
    7. Click Allow
    8. Click Yes to confirm that you want to allow the application to be run

    Now the application is allowed to be run on the system. 

    Note: To view all the currently excluded files and applications, select the Excluded tab in the App and file control view.

    You can also exclude files from being scanned when you are sure that the folder includes applications that are safe. To add files or folders that you want to exclude:

    1. Open the program
    2. Go to Viruses & Threats
    3. Select Settings
    4. Navigate to Virus Protection
    5. Click on View Quarantine
    6. Select the Excluded tab
    7. Click Add new
    8. Select the file or folder that you want to exclude.
    9. Click OK

    The selected files, drives, or folders are excluded from future scans.

    Please let us know if Lightroom is working properly now.

    Best regards.
