ComWar.A is the first worm to use MMS messages in order to spread to other devices. MMS (Multimedia Message Service) is a method of transmitting multimedia files, such as graphics, text messages, video clips, etc. over wireless networks, using the WAP protocol. Additionally, ComWar.A also spreads to other Bluetooth devices.
ComWar.A only affects cellular phones that use the operating system Symbian 60 series. If it is run within the first hour of the 14th of any month, ComWar.A resets the cellphone.
Keep in mind that ComWar.A needs the user intervention in order to be run on the cellphone. Before the malicious file is installed, the user receives a security warning.
No antivirus deletes this malacious file
So formating is the only solution
