How to remove deceptive Calendar events from mobile Apple devices?

What are deceptive Calendar events?

There are various questionable websites that contain deceptive advertisements, ask for a permission to show notifications, display deceptive pop-up windows and other intrusive content that should not be clicked. There are many people who have recently started to notice that there are various unwanted events added to the Calendar application on their mobile Apple devices. Research shows that these events usually are being added after clicking pop-up windows, notifications, etc., while trying to close them.

Deceptive Calendar Events scam

Once the Calendar app has those unwanted events added to it, then it starts to display deceptive notifications designed to open various untrustworthy websites. Research shows that those notifications open various scam websites, pages that contain deceptive advertisements, advertise questionable software, are related to gambling, pornography, adult dating, and so on. We strongly recommend not to trust any of those notifications and websites that get opened through them. They might be designed to deceive visitors into installing unwanted software, providing personal information, or even paying money for untrustworthy apps of some services (like remote removal of non-existent viruses). Trusting those pages may lead to unwanted downloads, installations, problems related to privacy, browsing safety, monetary loss, identity theft and a variety of other more or less serious problems. If it is already too late and there are various unwanted events added to the Calendar, then this problem can be solved by following the steps that are provided below.

Some examples of pages that may be opened through added events are safebrowsing[.]network, manualchecker[.]com and bestantius[.]com. These are the websites that are designed to trick visitors into installing some shady software by claiming that user's a device is infected with viruses. However, deceptive events in Calendar leads to a variety of other untrustworthy sites as well. Either way, none of them should be opened.

How did potentially unwanted applications install on my computer?

Quite often unwanted software gets downloaded and/or installed when people intentionally or accidentally click various ads, notifications or other deceptive content. It usually happens when they are designed to execute certain scripts. However, it is worth mentioning that unwanted downloads and installations occur only when people click some shady ad, notification, etc. In other words, deceptive ads, pop-up windows, notifications, and so on cannot cause downloads and/or installations without being clicked. It applies to ads that are are displayed while browsing the web on both mobile and desktop devices.

How to avoid installation of potentially unwanted applications?

To prevent unwanted apps from being downloaded and installed we recommend to download software from official websites and through direct download links. It is not recommended to use third party downloaders, installers, unofficial websites, Peer-to-Peer networks and other similar tools to download (or install) any software. Also, it is important to always check what are "Custom", "Advanced" and other similar settings of any download and/or install setup and deselect additionally included apps. One more way to avoid unintentional downloads and installations is not to click advertisements (notifications, pop-up windows) that are displayed on shady pages. Once clicked, they either redirect users to various untrustworthy websites or cause unwanted downloads, installations. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
