Beselo is a MMS and Bluetooth worm family that operates on Symbian S60 Second Edition devices. The Beselo family is very similar to the Commwarrior family but contains enough differences in the code base and behavior that it is counted as separate family.
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.
Beselo worms spread via Bluetooth and MMS as Symbian SIS installation files.
The installation file is not labeled with the .SIS extension. The SIS file is named with MP3, JPG, or RM extensions in order to trick the recipient into thinking that it is multimedia file.
If the phone user attempts to open the file, Symbian will recognize it as an installation file and will start the application installer.

Variants Beselo.C, Beselo.D and Beselo.E are closely related to Beselo.B.
