ive just got the nokia n86 8mp and have been reading a lot about the symbian system being vunerable to viruses-is this true? and i also read that the symbian system 2 can get viruses but the newer system 3 cannot, which is the n86?
finally if this phone can get a virus what is the best way to prevent it? i saw there is a netquin anti virus on the ovi store but its got really bad reviews and a lot of people say dont get it so finally is it reliable?

please answer all my questions in your answer
