Can I downlod virus guard to protect my iPhone?

Is there have? Becouse I was search on apps store but I count find out. If any one know help me

There's no significant risk of a virus on an iPhone, so you don't need virus protection. In fact, antivirus products depend on the same security holes that viruses do, and since iPhone does not have these holes, it doesn't need an antivirus. The only instances of malware infection on iPhones have been on jailbroken phones, and if you jailbreak your phone, you obviously don't care about security to begin with.

IPhone viruses are extremely rare, almost all IOS viruses were coded by security teams so they can patch what it hacked. So you do not need any sort of anti-virus on your phone.

You don't need virus protection on iphones (assuming its not jailbroke)
