AppDisabler.V is a malicious SIS file trojan, which tries to disable a number of Symbian OS system and third party applications. In addition to disabling applications AppDisabler.V replaces the phone operator logo and background image.


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

Installation to the System

When installed, AppDisabler.V will replace the main executable of several system and third party applications by overwriting their main executable file and replaces the operator logo and background image.

If any third party applications targeted by the trojan are installed on the device, then their main executable will be overwritten, and must be reinstalled to repair the damage.
