Summary
|
| SymbOS/Commwarrior.M is a worm that operates on Symbian Series 60 devices. The worm is capable of spreading both over Bluetooth and MMS messages. When Commwarrior infects a phone, it will start searching for other phones that are within Bluetooth range and sends the infected SIS files to the discovered phones. The SIS files that Commwarrior 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. |

Disinfection
|
F-Secure Mobile Anti-Virus will detect Commwarrior and delete the virus components.
If your phone is infected with Commwarrior and you cannot install files over bluetooth, you can download F-Secure Mobile Anti-Virus directly to your phone:
- Open the phone's web browser
- Go to http://mobile.f-secure.com
- Select link "Download F-Secure Mobile Anti-Virus" and then select the phone model
- Download the file and select open after download
- Install F-Secure Mobile Anti-Virus
- Go to the applications menu and start Anti-Virus
- Activate Anti-Virus and scan all files
- Reboot the phone to remove any Commwarrior processes that are still running
After disinfecting the phone, you can remove any remaining empty directories by going to the application manager and uninstalling the SIS file in which Comwarrior arrived. |
