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

Trojan:SymbOS/Appdisabler.D is a trojan intended to infect devices running the Symbian Series 90 operating platform, such as the Nokia 7710 phone model. It is distributed in a malicious SIS file named 'TIGER_HANDANGO.SIS'.

Due to an implementation error however, Appdisabler.D does not seem to be able to install in Nokia 7710 phones. It does install to Series 60 phones, but as it's contents are intended to harm Series 90 systems, it has no effect on Series 60 devices.

While this case seems to be a failed attempt on creating malware, we are adding detection and description anyway to prevent confusion if someone encounters this trojan.
