F-Secure Anti-Virus had a false alarm on this virus on June 15th, 2001.

As a result, F-Secure Anti-Virus might have detected "Lamerman.512.c" in master boot record or in file SUHDLOG.DAT on some systems.

Automatic action

To get rid of the false alarm, update to the latest definition files. The problematic update was released at 07:54 GMT on June 15th. It was replaced with a fixed update at 09:37 GMT on the same day.

F-Secure would like to apologize for the trouble caused by the false alarm.

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.
