Suspect a file is incorrectly detected (a False Positive)?

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 detection database 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

SUHDLOG.DAT is created to the root directory of drive C: during the setup of Windows. It contains backup copies of the original boot sectors of the machine and the system files. This file is not used by Windows unless you uninstall it - in which case the boot sectors and system files are restored.If your machine was already infected by a boot virus before installing Windows, the infected boot sectors will be copied to SUHDLOG.DAT. After this, F-Secure anti-virus products will find a dropper infection from this file. This is pretty harmless, and the best way to correct this problem is to make an extra copy of the SUHDLOG.DAT to a floppy disk which is stored in a safe place (an expert could fix the file manually if you need it for uninstall purposes) and just delete the SUHDLOG.DAT file from your hard drive.On a related note, F-Secure Anti-Virus had a false alarm of the Lamerman virus in this file on June 15th, 2001.
