The firm said it is among the first security vendors to include protection for Symbian OS 9, which forms the core of Nokia's Series 60 3rd Edition phone software. F-Secure already offers a version of Mobile Antivirus for handsets running Microsoft's Windows Mobile 5.0 and for Series 80 models such as the Nokia 9300 and 9500 Communicator devices.
Nokia's Series 60 3rd Edition software runs on phones such as its 3250, the N-Series and its new business-focused E-Series handsets, but F-Secure said the latest Mobile Antivirus version could protect all current and future phones running Symbian OS 9.
