Bluetooth-Worm:SymbOS/Cabir.B is a minor variant of Bluetooth-Worm:SymbOS/Cabir.A; the only significant difference is that the Cabir.B displays the text "Caribe-VZ/29a" on the start dialog when the worm first or when the phone reboots (Cabir.A displays "Caribe").


Alternatively, you can disinfect the system manually by installing a file manager application and manually deleting these files:

  • c:\system\apps\caribe\caribe.rsc
  • c:\system\apps\caribe\
  • c:\system\apps\caribe\flo.mdl
  • c:\system\recogs\flo.mdl
  • c:\system\symbiansecuredata\caribesecuritymanager\
  • c:\system\symbiansecuredata\caribesecuritymanager\caribe.rsc

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

There is also repacked version of Cabir.B that is packed into an SIS file which installs the worm into different directory and shows a text popup at SIS install. This is not a new variant however, as the worm executables are fully identical to the original Cabir.B; all differences are due to settings in the repacked SIS file.

For more details, see description of Bluetooth-Worm:SymbOS/Cabir.A
