Worm:SymbOS/Commwarrior.F is a worm that operates on Symbian Series 60 devices. The worm is capable of spreading both over Bluetooth and MMS messages.
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 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.
Commwarrior.F closely related to variant Commwarrior.A.
When Commwarrior infects a phone, it will start searching for other phones that are within Bluetooth range and send infected SIS files to the discovered phones. The SIS files that Comwarrior sends are randomly named, so that users cannot be warned to avoid files with any given name.
In addition to spreading over Bluetooth, Commwarrior will also read the user's local address book for phone numbers and start sending MMS messages containing the Commwarrior SIS file to those numbers.
