Calendar virus – scam that seeks to convince mobile device users to click on potentially malicious links

Calendar virus is spam that is sent via the accepted Calendar Event

Calendar virus is a phenomenon that can be encountered on iPhones, Macs, and Android devices, including phones and tablets. The culprit of the unwanted behaviour is the suspicious invites within Apple's Calendar events or Google Calendar and can start appearing on users' phones and tablets seemingly out of nowhere. Nevertheless, an elaborate scam scheme is used in order to make Calendar virus a persistent and annoying threat. In most cases, the attackers send thousands of users malicious emails with the Calendar event invites or embed prompts within various websites.

The main purpose of the Calendar virus is to make users click on the links that are embedded within persistent Calendar notification pop-ups. These links can come from a variety of websites, including Important-notices.com, Alert-booster.club, iPhone-fix.com, and dozens of others. The Calendar spam is filled with discounts, deals, sales, and other attractive offers which might seem legitimate, although are mostly a scam related to the infiltration of potentially unwanted programs/malware, loss of money, or the disclosure of personal information to malicious third-parties.

In most cases, users believe that they did not invite iPhone Calendar virus on their devices themselves. This happens due to stealthy infiltration of unwanted events within the phone. In most cases, users accidentally click on a pop-up message which automatically establishes unsolicited profiles, email accounts, and other persistence mechanisms within the device. In some other cases, crooks send users emails that prompt them to accept a calendar invite. This results in users receiving Calendar scam messages on a regular basis, sometimes reaching intervals as frequent as 10 minutes.

Due to the intrusive nature of Calendar virus events, users might believe that it is related to adware or malware infection. While the device is relatively compromised due to unwanted pop-ups, it is important to note that the events are stemming from official Calendar app. For that reason, users might be confused and believe that these messages are legitimate.

Calendar virus is unwanted activity that uses various techniques to make users click on promotional links via the Calendar app

Typically, Calendar virus notifications include a variety of eye-catching titles which come from an array of URLs. Cybercriminals use various social engineering techniques to make the embedded link to be attractive to the user – a few examples include:

• Your iPhone Xs Max is ready for PickUp
• You Have Won iPhone X Max from AppleStore
• You have (1) Pending Package
• Ensure Your Online Protection, Click Now!
• (1) Congratulations, you won!
• Kate send you 5 pictures
• It's your lucky day
• Your iPhone is not Protected! Click to Protect
• Click NOW to Secure Your iPhone
• iPhone Security Pack Discount
• Viruses Alert – Check Protection NOW, etc.

As evident, in some cases, users are trying to be intimidated – it is implied that the device is infected and needs protection. These particular Calendar virus messages are extremely dangerous, as users might be redirected to malicious sites where they will be asked to install potentially unwanted apps or malware.

In other cases, victims might end up on a website that offers to fill in a survey in exchange for an expensive gift. These scams usually revolve around users providing their credit card details, which are later stolen by malicious actors. At the same time, the promised gift, such as iPhone, Samsung Galaxy, PlayStation, or another expensive gadget, is never received. Due to all the scams that users are fed over time, the device can start suffering from much more than just the Calendar virus.

Calendar virus uses social engineering in order to make users click on potentially malicious links

Keep in mind that security experts highly discourage users from clicking on any links via such events and remove Calendar virus from their phones and tablets as soon as possible. There are several ways to do that, so please check the full guide below.

Nonetheless, if you clicked on the Calendar event pop-ups and downloaded suspicious software, there is a chance that you infected your device with malware. In such a case, the Calendar virus removal may involve several checks, including a scam with anti-malware software – we suggest using SpyHunter 5Combo Cleaner or Malwarebytes.

Once that is done, you may find that your iPhone or Android device still operates slowly – this is especially true for older models. In such a case, we advise using reputable optimisation software (our choice is ReimageIntego).

Prevent the infiltration of unwanted ads on your phone or another device

There are several methods of how your Mac, Windows computer or remote devices can be spammed with ads. First of all, it is important to note that some ads are embedded within certain sites and can sometimes be removed with the help of such tools like ad-blocks or privacy and safety-focused browsers. However, since ad clicks are extremely lucrative to various parties, some malicious actors attempt to distribute ads in less than fair and secure ways. In other words, a clever marketing slogan is not the same as a claim that your phone is infected with viruses.

In most cases, Calendar spam prompts include various attractive titles that should make users click on the provided links

Therefore, it is always important to differentiate between malicious and fair ads that could sometimes even help you find what you are looking for online. The best way to prevent malspam is by ensuring that you behave carefully when performing your daily online routine, and online security can go a long way.

Malicious Calendar events are typically injected when users click on a hyperlink while browsing the web or after accepting an invite via a received email. Once one of such emails is clicked, users might compromise their device and ads will be displayed regularly, regardless if one wants them or note. To prevent such course of events, follow these tips:

• Never accept Calendar invites via emails, especially those that are coming from unknown sources. However, declining them is also not recommended, as the action would simply show that an email account is active (this could later result in further spam emails);
• Avoid visiting high-risk websites, such as free video streaming sites, torrents, software cracks, and similar;
• Do not believe prompts within your browser which claim that something is missing or your device is infected with malware – they can imitate legitimate system notifications in order to make you installed malware;
• Enable a robust security software that could protect you from malware installation, install ad-block, and be more careful when trying to close ads that act erratically.

Calendar spam will often include various promotions, although they should never be trusted
