It’s worth remembering that some of the factors outlined below can usually be applicable to hardware problems or software glitches too, so if you see them it doesn’t automatically mean you have a virus.

Malware and viruses don’t like to announce their presence, lest you become aware that they are on your system, but there are some quirks or abnormalities that can indicate they are at work.

What has most likely happened is a spam text message has caused appointments to be added to the calendar. There is no iPhone Calendar Virus and your calendar has not been hacked.

Such unofficial app stores are far more likely to suffer from viruses and malware-laden apps. In fact, the majority of successful malware attacks on iPhones have been directed at models that have been jailbroken, which gives the owner access to software that hasn’t been checked by Apple employees.

The App Store vets all submitted software for potential threats, and while mistakes are occasionally made (there are literally millions of apps to check), this mostly keeps iOS free from nasty agents.
