Calendar virus is a scam notification created by crooks to profit from fraud
Calendar virus is an iPhone-related scam that helps to trick mobile users into clicking on ad-like events. It's a non-typical member of the iPhone virus family as this particular scheme has been programmed to target the Calendar app by filling it with fake event links, which keep displaying reminders when the scheduled time exceeds. Nonetheless, the same activity can be found on Macs as well.
Each notification contains a link and a short description, such as “Kate send you 5 pictures” or “It's your lucky day.” However, there's no option to disable the Calendar notifications easily, and that's the main reason this type of issue is particularly disruptive and annoying to users.
These questionable entries appear seemingly out of nowhere. The Calendar spam may invite people to participate in various deals, sales, register to the dating portals, claiming prizes, etc. Often people fall for clicking on suchlike ads as they are displayed within the legitimate app, which makes them seem more trustworthy (it is not the case, however).
In most cases, users believe that the Calendar spam activity is related to malware, although it is not the case. In most cases, deceptive techniques (phishing email, fake alerts on suspicious sites, etc.) are used to add a calendar entry on iPhone or Android or a malicious profile into these devices. Thus, the only way to get rid of these persistent scam messages is by deleting these entries. Remember, URLs like notice-iphone.club or alert-booster.club should never be trusted.

Below are the most commonly encountered domains that actively distribute the Calendar virus.

Notice-iphone.club is one of the most active addresses that are used to deliver Calendar event spam to victims. In most of the cases, users visit websites of poor reputation that provide some type of useful functionality, such as TV show streaming, online gaming, porn videos, etc. These sites are usually filled with intrusive ads that may pop-up seemingly out of nowhere, just at the time when users tap on their screens.

Once the new entry is established, users start receiving Alert-booster.club pop-ups via their phones of various content. In most cases, threat actors behind this scam use fake messages in order to intimidate users and make them download unknown applications, provide personal information by registering to some allegedly useful service, or visit websites of dubious content.

Some of the Calendar app versions trigger redirects to fake websites of a supposed International E-mail Associations
Protection-fix.fun is the site that meets the general term of the Calendar virus because it shows warnings and pop-up alerts about malware issues or security problems that, in most cases, are not related to the infected machine at all. This is the domain that focuses on the message stating that the iPhone or iPad is not protected.
Of course, the message that shows up in the calendar application and as a pop-up, web browser redirect triggers particular site opening and other pop-ups, traffic reroutes. These claims are false and created to trick people into allowing other site appearance and redirects to shady sites that can promote tools and deliver dangerous or even malicious programs.
Yet another site with deceptive purposes – Notice-booster.site offers to help with virus issues that randomly got detected by the suspicious program. Events on the Calendar application encourages people to allow the program on the system or even purchase the rogue security/ “antivirus” tool. This site can also show commercial content besides those misleading messages, so people risk getting their personal information revealed to third-party or malicious actors.

calendar virus versions rely on false claims about system issues and iPhone malware protection.
Notice-device.club site appears in the Calendar event message claiming that Your device is vulnerable to online threats, cyber malware, and can get damaged when the user is not taking any actions. Apple devices that this alert shows-up on, in most cases, have no particular issues.

If that still happens and the machine gets damaged, rely on ReimageIntego that should find and fix particular parts of the system that need optimization.
Biogrammad is another Apple iOS devices targeting scam campaign that involves interference with calendar applications on mobile devices. It can appear on iPads, iPhones, iPods even. The message that is related to this particular domain states about not protected iPhone and issues regarding malware, cyber infections, or even hardware issues.
It comes on the screen out of nowhere and triggers those entries in the calendar, so people get messages, alerts about the event that is a scammy message instead. These social engineering tactics aim to get users' attention, cause clicks, and page visits on sponsored pages. The particular Biogrammad.club also spreads around by using free application promotions, installations, and shady distributor content.
Scammers improve their methods and make their schemes more tricky than ever
Junk email notifications include invitations or additional pop-ups with Accept or Decline buttons. Unfortunately, no matter which button you click they all trigger the same function. In some cases, such deceptive material leads to other push notification redirects, or you encounter direct pop-ups on the desktop from there, install the PUP, or a virus without noticing.
Experts note that this interaction may also be needed for a scammer to make sure that your email address is active and can be targeted more with scammy messages and malware-laced content. You should simply delete the received email that raises questions or is suspicious due to content or the initial sender. This is probably the best way to avoid spam campaigns and exposure to these shady services and online material.

Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
