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").

Disinfection with two Series 60 phones

F-Secure Anti-Virus for Symbian series 60 phones will detect the Cabir and delete the worm components.

After deleting worm files you can delete this directory:

  • c:\system\symbiansecuredata\caribesecuritymanager\

Special Disinfection Tool

Or you can use our free disinfection tool, available for download as a SIS file or a zipped file . The tool can also be downloaded directly to the phone:

  • Open web browser on the phone
  • Go to
  • Select link "Removal tool for Cabir"
  • Download the file and select open after download
  • Install F-Cabir tool
  • Go to applications menu and start F-Cabir
  • Select scan and answer yes when tool asks do you want to disinfect

Manual Disinfection

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

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.

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.
