This from McAfee blogs regarding this latest malware… Occasionally we find PC malware that can have an effect on mobile phones or vice versa. The W32/Mobler worm installs SymbOS/MultiDropper.CC to any Windows system it infects. The Symbian malware has no effect on the PC. Similarly SymbOS/Multidropper.CC installs W32/Mobler to the memory card. The mobile version is arguably more effective as inserting a memory card with Mobler into a PC with AutoRun configured is enough to cause an infection.
