How to delete this iPhone malware?

Hi Raimondas30,

Welcome to Apple Support Communities. We see that you are trying to remove a certificate from your iPhone. This doesn't indicate malware and here are some resources that should help to remove it.

First, it may be related to a configuration installed by your IT team if you use your iPhone for work or school. In that case, this information from Install or remove configuration profiles on iPhone - Apple Support can help.

"Configuration profiles define settings for using iPhone with corporate or school networks or accounts. You might be asked to install a configuration profile that was sent to you in an email, or one that’s downloaded from a webpage. You’re asked for permission to install the profile and, when you open the file, information about what it contains is displayed. You can see the profiles you have installed in Settings > General > VPN & Device Management. If you delete a profile, all of the settings, apps, and data associated with the profile are also deleted."

In addition, the information in Trust manually installed certificate profiles in iOS and iPadOS - Apple Support and Install custom enterprise apps on iOS - Apple Support, which generally are for mobile device management as mentioned above, may be helpful.

All the best.

Sign out, and sign back in with your known AppleID on your computer. That .info address likely is a fake account.
