non s60! Cheers, you don't need any antivirus, because there aren't any virus's for Series 40 Symbians and never will be. And no movie players either, its a phone not a laptop. It can only play 3gp and mp4 files but you can convert any media on your PC to 3gp or Mp4 and send em over to your new phone.
Apps and Games, it will only run J2ME. There are plenty, i'll leave that for someone else....
and congrats on your new phone.
