If I use quick start to set up my new iPhone, will malware transfer from my old iPhone 11 Pro?

1. Find and delete all apps that you did not install yourself.
2. If your iCloud storage is full then it is not not saving photos on iCloud. You are correct that the photos are only saved on your iPhone.
3. Glad that you have changed the password to the Apple ID.

I was going to initially recommend setting up the new iPhone separately and not transferring anything from your old iPhone. I was hoping that you had an iCloud backup of your photos and that you would simply restore those photos on your new iPhone through iCloud. Unfortunately, your photos are only on the iPhone. Based on this, my recommendation is that you find and delete all apps that you personally did not install and then begin the transfer of data to your new iPhone.

Questions for you:

1. What makes you believe that you have malware/spyware on your iPhone? Please provide specific examples of why you believe so.
2. Do you use iCloud for photos? Open Settings ➡️ Apple ID (Your Name at Top) ➡️ iCloud ➡️ Photos: Is this switch set to ON or OFF?
3. Do you share your Apple ID and Password with anyone on another device?

I ask those questions to understand whether there is malware/spyware on your iPhone. It is nearly impossible to get that software installed on an iPhone unless the iPhone has been jailbroken. To answer your question, YES, if you use the Quick Start method then ALL data from your old iPhone will be transferred to your new iPhone.
