iPhone virus is the general term that describes threats like greacore.com virus because of this particular site displays those fake alerts and acts as a part of the social engineering campaign on mobile devices. It manages to alter various settings and affect a few parts of the iOS, but it doesn't seem to act as a PUP or any other type of intruder on macOS or Windows devices.
Malware that spreads on iPhone devices particularly can go for techniques like Alertsp.club and show false system warnings, other pop-ups with claims about security issues. Or even go for the way that Alert-booster.club uses – going for a particular type of application. This Greacore.com is nothing but adware even though those alerts may seem legitimate and scary enough to trick you into allowing the remote attacker to access the system of your machine.
Various pop-up windows and messages may appear on the screen when the redirect to Greacore.com shows up, but all of them should resemble a warning like this:

Greacore.com primarily occurs on iPhones and frustrates people with those alerts and false warnings, so the site is not acting the same on computers. However, other Apple products can still get similar messages since the scheme is universal, and all the claims about the heavily damaged device or virus infections are more common.
You should ignore any of those messages about damage and infections because the biggest risk is the program that scammers behind this site try to promote and distribute. You need to remove Greacore.com from the screen by at least exiting the browser or the pop-up without allowing anything or clicking on any of those ads and redirects. You may trigger threats that for real corrupts the device and can lead to hacks or loss of data. 
If you get to visit those dangerous pages and click on many ads, redirects, different types of material, you may need to perform more than Greacore.com removal because your device can get infected by the more dangerous intruder than PUP. However, there are more risks since this site is focusing on scammy messages because the pop-up with the false alert can result in:
- installed useless program;
- downloaded malware;
- attacker accessing your computer;
- keystroke loggers used to obtain personal details about you;
- modified settings of the machine.
When you encounter anything related to redirecting or claims about the system out of nowhere, you should first check the source of the message, and when a site that is unfamiliar like Greacore.com shows those messages, be aware of the possible outcome of getting the malware installed on your system. When it comes to phones and mobile devices the termination and even exiting the website is difficult since you cannot easily click the X button.
Therefore, automatic methods for Greacore.com elimination are more recommended by various experts[3] and security researchers. We also note that system changes can lead to more severe issues and damage to the machine, no matter if it is a mobile phone or a PC. Get an application like FortectIntego that can check for affected files or corrupted programs and repair that damage for you. 
Be suspicious and pay closer attention to details
Official pages of system tools and other applications can seem legitimate and resemble other sites that distribute proper optimization utilities and so on. However, pay attention to EULAs and privacy sections on sites you choose as the source of your applications, so you can control the installation process and be sure about the software you get.
If you go for torrent sites, free download sites, or services that provide all the freeware online, you can end up with PUPs or additional intruders when the insecure installation is initiated. Advanced or Custom options of these installations can be a solution because by selecting such a method, you can see the full list of programs included on the setup, so you choose what to install an what is useless or at least suspicious.
