I need mobile scanner for viruses which could be a? separate? mobile appllication for each most common mobile platforms such as symbian, windows or android or it could? be an application which will detect mobile device and make memory and sd card available for scan to your laptop or pc (when mbile is connected to your laptop thorugh data cable or over bluetooth). If you already have an application then that is great. There are sdk available which can be used to make your mobile memory available to the pc. If you can find virus smaples such commander, caribe etc then that would be great.
