Mobile phone security

Do you have to have internet security on your mobile phone?
I've got Norton at the moment on my phone but I'm wondering whether to renew it when it runs out.

Its goos if you do have internet security if you are browsing the internet/playing games or watching videos on the phone as it can get attacked by viruses or malware. I think its a good choice to update to whatever security options you've got when the current one runs out.
