Trojan Horse
Systems Affected:

SymbOS.Drever.C is a Trojan horse that disables certain Symbian OS antivirus programs by overwriting their startup files. It is reported that the antivirus programs affected by this Trojan are Kaspersky, Simworks, and F-Secure Symbian antivirus products.

    Symantec recommends the following to protect against this threat:

    • If Bluetooth is not required, it should be turned off.
    • If you require the use of Bluetooth, ensure that the device's visibility setting is set to "Hidden" so that it can not be scanned by other Bluetooth devices.
    • Avoid use of device pairing. If it must be used, ensure that all paired devices are set to "Unauthorized". This requires each connection request to be authorized by the user.
    • Do not accept unsigned applications (no digital signature) or applications sent from unknown sources. Be absolutely sure of the origin of the application before accepting it.
