For removal tools and instructions, see the Removal section of Worm:W32/Downadup.gen.

Resolving 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 to F-Secure Labs 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

The .JOB file used by the worm is detected as it is part of the worm's propagation routine. Downadup attempts to spread itself using Windows Scheduled Tasks. The .JOB file defines a scheduled task, which in Downadup's case triggers an execution of the worm library via rundll32.exe. Legitimate tasks are usually located in the following folder:

  • WINDOWS\TASKS\
