Anti-virus for iPhone

There are no known viruses in the wild that can affect an iPhone that has not been jailbroken.

So long as you have not jailbroken your phone, or downloaded a management profile in order to install an app from outside of the App Store, there is nothing that any antivirus or anti malware app could possibly do for you.

If you have, restore your phone to factory settings and set it up as a new device.

No support is available for jailbroken devices.

A non-jailbroken phone cannot get malware or a virus so there is nothing to check for and no anti-virus software needed. Why do you think you may have a problem?
