Antivirus software for iphone

No. A virus is a type of malware that spreads copies of itself from one infected app or script to others. IOS is very locked-down and does not allow apps to modify files containing other apps. A “virus” cannot spread to other apps, and an “antivirus” app could not disinfect other apps even if there were viruses in the first place,

Antivirus will do nothing to help your phone, but it will slow it down and interfere with the protective software built into the iOS on your phone.

Even if the antivirus is free, it would not be worth the money.

Same statement is true for VPN, unless your company or school requires it to log on to their network.

How about anti malware and phishing software?

Anti-virus or anti-malware, it's all the same useless stuff.

Phishing isn't something you can really prevent unless you turn off email, messaging and don't answer phone calls. Preventing being a victim of phishing scams is something only you can do. You do this by educating yourself.

Here are some articles to start with.

Recognize and avoid social engineering schemes including phishing messages, phony support calls, and other scams - Apple Support

Identify legitimate emails from the App Store or iTunes Store - Apple Support

No, not if you’d like a seamless experience with your banking apps and Apple Pay and Apple Wallet.

Having with popups

Having issues with popups

If you see a popup, the website was paid to allow the popup to occur on their site.

Not much you can do about that other than avoid the website. Better quality websites don't allow popups.

You’re welcome and I hope you have a great weekend!
