A file or program has triggered a DeepGuard heuristic detection because it performs (or contains instructions for) actions that resemble known harmful programs.


The F-Secure security product will automatically block the file from running.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

About DeepGuard

When a file or program is first launched, F-Secure's security programs verify its safety from the Security Cloud file reputation service. If it cannot be verified, DeepGuard starts to monitor its behavior. DeepGuard automatically blocks files or programs that try to make potentially harmful changes to the system.

This detection indicates that a file tried to make potentially harmful system changes. For example, the file may have tried to:

  • Change the settings in the Windows registry,
  • Turn off important system programs,
  • Edit important system files.

If done with malicious intent, such changes can compromise the security or the integrity of computer or mobile device, or the data stored on it.
