Is there an anti virus or malware scan I can get on my iPhone 4?

Is there an anti virus or malware scan for the iPhone 4 that I can get from the apple store? If so what's the name? Also is there something I can get to stop ads poppin up on games?

No, there are none of those in the iphone, and you can get the ads off by getting the pro version

You don't need that on iphones, other phones need it but not iphones. As far as ads, no thats built into some of the free games, etc.
