VPN

Nope. There is no such thing.

#1. Using a VPN to access the Internet does absolutely nothing to protect your privacy or enhance the security of your communication. All it does is put ALL of your data traffic in the hands of one company.

#2. TANSTAAFL. If it is "free" you are not the customer, you are the product...

like the TotalAV keeps telling me.

Total AV is not an Apple App, it is an anti-virus app, which is a total waste of time or money if they charge anything for it.

You don't need an AV app on your iPhone.

Most antivirus apps for your iPhone aren't really designed to find viruses. They are often security programs that bundle multiple functions to justify the price asked. It is quite difficult for security software makers to make a really good antivirus app, because Apple has pretty much boarded up the system.

Remove it.
