What is a calendar virus?
App calendar malware, also called Calendar Virus for iOS or iPhone calendar virus, is a kind of spam targeted on Apple devices, that adds fake subscribed calendar accounts to a user’s device without their consent. Affected devices could be iPads, Mac computers, Watch or iPhones. As a result of the spam, users receive notifications for “events” containing malicious links. Its effects are similar to what adware brings to the system it runs in. The terms
“iPhone calendar spam” and
“iOS calendar spam” refer to this Apple OS activity. This type of notification may contain disturbing headers to force you to follow the link. Here are examples of similar messages:
- Virus on iPhone? ! clean up now
- Ensure your online protection, click now!
- Your phone is not protected! Click to protect
- Keep your iPhone safe from malicious attacks!
- Your iPhone is infected with a virus! delete it now
Some messages will arouse the user’s curiosity and sense of urgency. Usually, after a user follows something like this and clicks a link, it launches malicious sites or questionable software on his device. Alternatively, it can redirect the victim to phishing pages.

Like most other malware and viruses, calendar viruses are often spread through the same malicious sites as they advertise, or social engineering. So, how to get rid of calendar virus? Here are some typical ways of being infected by that nasty thing:
1. Attackers have got hold of your email address.
If the attacker has your email address, it means that in the future, you will be a target of email spam. This happens after you enter your email address on unfamiliar websites to confirm something or to buy a product. Usually, such shady sites can sell your information to make money – and they don’t care about customers’ comfort. In rare cases, emails leak when companies suffer from data leaks.
2. You inadvertently clicked on a malicious link.
Some scam websites might use fake captcha puzzles to bypass site warnings and trick you into downloading malware. Alternatively, they can use disguised calendars as captchas to trick you into subscribing to them. If you’re in a hurry, clicking OK might be easier than selecting any other option.
3. Receiving a spam link by text message
After clicking on a spam text that directs you to
“track a package”, you subscribe to a calendar full of appointments, like
“critical threats” and similar warnings. One of these spam messages might request tracking information and provide a link for accessing the Calendar.
