How to run a scan on an iPhone

On an android phone you can 'pull down' the screen to run a scan when in your Norton app. I have just added an iPhone but it does not appear to work in the same way. Does anyone know how to run a scan on an iPhone please?

Thanks for the input all. Really helpful.

Thank you, your comments very much appreciated.

 If you are referring to a malware scan, there is no malware protection in Norton 360 on an IOS device. See this article from howtogeek . com for an explanation of why it is not necessary.
