Calendar virus can trigger many push notifications and raise questions this way. Also, constant calendar invites, deals, and sales from users that you don't recognize are spam. iCloud calendar application and other apps can automatically notify you about every notification, and spammers misuse this feature for their advantage. 

Unfortunately, there is no particular solution for the issue, and there are many versions of the same Calendar notifications virus. You cannot mark those invites as spam or prevent them from people that are not in your contacts, but invites can be declined, and users may respond negatively to them. You can get this threat by responding to a scammy email too when all the buttons stating Allow or Block trigger the same notifications. 

Pop-up notifications lead to redirects, to shady or malicious pages and false calendar events. Then you are left with a hard question and a few methods for Calendar virus removal. Since this is a threat that managed to change calendar preferences it can also manage to change settings of your machine, add files, programs, or disable some features. You need to take that into consideration and make sure to remove all potential risks of getting these intrusive symptoms repeated.

There are many different infections and techniques that can get used directly on the website to collect information about your online browsing habits or record keystrokes directly on targeted domains. 

Calendar spamCalendar virus is the campaign that aims to expose people to deceptive content and redirect them to sponsored sites where views get collected.

Calendar virus is connected to hundreds of potentially dangerous domains

Multiple domains could be used to deliver suspicious notifications directly to users' screens. These persistent messages use social engineering in order to make users click on the link and then proceed with whatever crooks intended them to.

Regardless of techniques, all of Calendar virus developers seek only one goal, which is money – be it valuable personal information that could be sold for marketing purposes, installation of unwanted programs that third-parties get a commission on, or user exposure to intrusive ads. Below are the most commonly encountered domains that actively distribute calendar virus.

Clicking on iPhone Calendar ads poses a risk to your PC's security because the provided hyperlinks may be linked to rogue pornographic websites, fake software download sites, or rogue survey domains. Therefore, even though some slogans positioned among Calendar events seem appealing, do not fall for clicking on them. The most common Calendar virus ads are:

  • Try Apple news + free
  • Your iPhone may be exposed to 4 viruses
  • Click now to secure your iPhone
  • You are exposed online, click to fix
  • Virus alert – check protection now
  • (1) Congratulations – you won!
  • It's your lucky day
  • You have (1) pending package
  • iPhoneXs is ready, pick it up, or choose delivery!
  • iPhone security pack discount
  • Hackers might try to take control over your iPhone! CLICK NOW to stay protected.

Notice-iphone.club

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. As a result, they start seeing notifications from Notice-iphone.club.

Calendar virus prompts from Notice-iphone.club are geo-location-based so that users might see phishing messages in their native language – this is very typical to ad content. Typically, the content of notifications includes messages from alleged secret lover, threatening messages that claim phone vulnerability, claims about malware infections, etc., so users may see Calendar entries like “Kate sent you (5) pictures,” “You are exposed online,” “Clear your iPhone from malicious attacks!,”Viruses alert – check protection NOW,” etc. As evident, you should remove Notice-iphone.club pop-ups instead of clicking on links inside these scam notifications.

Alert-booster.club

Alert-booster.club is another domain that infiltrates iPhones with intrusive Calendar spam. Just as with other similar scams, intrusion happens either when users accept a calendar invitation via a phishing email or when they accidentally click on a link steaming from a malicious website.

Once the Calendar virus 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.

In any case, you should not click on Alert-booster.club pop-up messages that read:

  • Viruses on your iPhone?! CLEAN THEM NOW
  • Ensure Your Online Protection, Click Now!
  • Who wants a Free Apple Music Subscription?
  • Your Phone is not Protected! Click to protect, etc.

Calendar virus notificationsTypically, crooks use domains like Alert-booster.club and Notice-iphone.club to deliver intrusive pop-ups to users

Notices Cleaner Best

Notices Cleaner Best is yet another iPhone Calendar app scam, which may be triggered either by a potentially unwanted program (PUP) on the device or a malicious website that has added calendar events without the user's permission. Also known as notices-cleaner.best, the scam may be used for spreading malware or data extortion campaigns.  Notices Cleaner Best scam typically creates a scheduled calendar event saying: 

iPhoneXs is ready, pick it up, or choose delivery!

Clicking on the link provided below the notification redirects to a questionable website, which clarifies a supposed reason why you've been selected to participate in a lottery and then asks to fill in the form indicating your name, address, telephone number, and similar information. No matter how seductive Notices Cleaner Best ads may seem, do not submit the required information as you may unconsciously subscribe to useless service or, even worse, get scammed. 

Calendar virus on Apple devicesMobile Apple devices are actively spammed via a Calendar app, which generates fake scheduled events due to malware

Since there is no antivirus software for Macs, experts recommend checking Safari, Google Chrome, or another web browser for unfamiliar add-ons and disabling them. Besides, you can prevent malicious events from being added to the Calendar app by changing Event settings. A full explanation of how to do that is given below. 

Notices Booster Best

The latest Calendar virus has been reported at the beginning of January 2020. Previously referred to as a notices-booster.best virus, the relaunched spam campaign displays misleading Calendar event alerts named as Notices Booser Best, which congrats a potential victim for being a winner of an annual competition and demands to follow the instructions to claim the $1541 worth reward. 

Notification №6538 CONGRATULATIONS!
Your e-mail address is the winner of our annual competition! Your prize money is $1541. Follow the instructions on the website to get it (URL address)
 The content of the Notices Booser Best scam may vary, though the provided link typically redirects to a bonusmail website, which represents itself as an “International Association of e-mail providers.” Clicking on the button “Click on this button to confirm your participation” is the point where people may get tricked in many ways. 
Calendar virus versionsSome of the Calendar app versions trigger redirects to fake websites of a supposed International E-mail Associations
In any case, do not click on Calendar events related to Notices Booser Best virus as they are used for collecting people's email addresses and subsequently involving them in malspam campaigns and other deceptive activities.

Notices Fixer Best

Notices Fixer Best or notices-fixer.best is yet another misleading Calendar app even notification on mobile Apple devices. According to experts, it's distribution technique does not differ much from its predecessors. Typically the misleading notifications emerge after opening a spam email message that includes an invitation alongside the usual Accept, Decline, or Maybe buttons. It doesn't matter which of the buttons is clicked, malware may be downloaded to the system. Besides, the sender of the email gets a notification from you as a grant that the email address is active. Consequently, bad actors behind suchlike Calendar virus alerts can leak the targeted email address and keep sending invitations to various events.
 
If criminals receive permission to add an event to the Calendar app, the intrusive prize giveaways and other hard-to-believe offers start coming out straight from the legitimate Calendar app on iPhone or another device.

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[4] 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.

Also, those redirects, sites with false messages about malware infections, other risks, lotteries, prizes, and so on are symptoms of the potentially unwanted program or the adware-type intruder. This application is the one that triggers redirects and the constant appearance of shady websites with questionable content.

PUPs spread around during freeware installations when the person who downloads wanted software chooses recommended or quick options and automatically allows all the intruders to come on the device. You need to choose Advanced or Custom installations and, more importantly, rely on official developers and application providers to avoid this pre-bundling in the first place.

Calendar virus removal means the removal of PUPs and recovery of iPhone's settings

Since the Calendar virus is the threat affecting various parts of the device it can get pretty dangerous over time. You should clean the machine and eliminate the potentially unwanted program that triggered those unwanted calendar entries or can lead to additional issues with the system. There are tons of domains that trigger redirects to sponsored or affiliated pages and make these spam campaigns happen.

You should go to the Calendar application and tap Calendars at the bottom. You should locate all the suspicious calendars and tap the i in the circle to get more information and options. Scroll to the bottom, so you can press Delete Calendar. After that, you may need to block pop-ups on your browsers and clean, additionally installed extensions or tools.
