This description is for the Trojan:SymbOS/CDropper malware family, which contains numerous variants. Trojan:SymbOS/CDropper functions, as its name suggests, as a dropper. On arriving on a new system, it installs Cabir variant(s) into several places in the device file system.
Some of the installed Cabirs will replace system or common third party applications. If the user has one of these applications installed, it will be replaced with Cabir and its icon in the menu will go blank.If the user clicks on one of the replaced icons in the menu, the Cabir executable will execute and try to spread to other devices.
