virus

Thank you for reaching out to the Apple communities.

• An iPhone cannot get viruses or malware unless you have jailbroken it (if you don't know that jailbreaking means, then you probably haven't done it).
• Any alert that says you have a virus or have been hacked is a scam. In this case, someone (a sketchy company) wants you to download their VPN.
• Never trust an email, text, popup, website, or phone call that says you have a virus (even if it looks like it's from apple). Never download anything these messages tell you to download, and never give them any information about yourself or your computer.

It’s a malicious ad designed to scare you.

Ignore it, stop going to websites that rely on such ad or install an ad blocker.

A scam. Close the page and move on.
