These pop-ups typically aim to convince users that their computers, phones or tables need cleaning due to alleged viruses, and direct users to the page where they are asked to download dubious software. If you got an Alert Booster Club calendar message, you should be aware that it is a scam, and you should never click on the provided link.

Due to the intrusive nature of Alert-booster.club notifications that popup several times a day, some may believe that their devices have been infected with adware or malware.^[1] However, in most cases, the suspicious pop-ups are rarely a result of an infection but rather a calendar entry that was added via the email, an unwanted email account, or a profile that was appended without users’ notice. In any case, the so-called Alert Booster Club iPhone virus removal instructions can be found at the bottom section of the article.

Practice safe browsing to avoid Calendar spam viruses

Calendar spam notifications are extremely intrusive and persistent, and most are unaware where they are coming from or how to remove them – these are the reasons why users tend to call such intrusions as “calendar spam virus.” Nevertheless, it is not entirely correct, as the device is not infected, as Calendar spam is caused by a malicious profile that has been added after clicking on a link online or after receiving a phishing email. In other words, iPhone Calendar is just a tool used by cybercriminals to spam users with unwanted notifications and links to malicious websites 

Those who receive a phishing email are usually asked to accept a calendar invitation. Because the invitation is coming from an unknown person, most will decline it immediately and think nothing of it. However, they soon notice that the calendar invitation prompts are sent regularly – malicious actors became aware that the account was active as soon as the invitation was declined. Thus, you should delete such an email instead of pressing anything and also report it as junk.

In case you did not accept the calendar invitation via the email, and you are still encountering the Alert Booster Club iPhone spam, you must have clicked on a link online either accidentally or purposely. Experts advise enabling ad-block, employing web-shield via the anti-virus program, and trying to avoid high-risk sites (typically online streaming, gambling, torrent,^[2] etc.).
