It sounds like you’re seeing a “McAfee scanning your device” pop-up on your iPhone. Here’s what you need to know:

If you need help verifying or removing anything, reply with more details (e.g., does it appear in a browser or as a system notification?).

iPhones do not allow third-party apps like McAfee to perform background system scans in the way that pop-up suggests. Real security software on iOS works within the app’s sandbox and cannot scan system files or show system-level “scanning” alerts from a webpage.

You visited a website that displayed a fake browser pop-up designed to look like a McAfee notification, often claiming viruses or performance issues to trick you into tapping, calling a number, or installing a malicious profile or app.
