Best app to remove a virus on my iPhone 4s
I'm 99% sure there is a virus on my phone. When connected to iTunes there is a large chunk of my phone taken over by something iTunes can't describe. It's marked as other in my usage bar. I've tried everything to get rid of it but I have this feelings it's a virus sitting dormant on my phone. What is the best app to remove this type of thing. I've done multiple virus sweeps on my laptop but it can't find anything hidden that way. If anyone can help I would very happy. It's eating my data and my storage space!
Thanks for any info
iPhone 4S, iOS 6.0.1
