"Your system is infected with (3) Viruses” when opening a Safari tab

This message came up when I was opening a new window in the Safari browser and makes all sorts of threats if I don’t call Apple Support at 1-866-726-**** and follow Virus removal procedure immediately. I’m always wary of these things and just want to know if anyone else has run across this particular warning.

It's phishing.

Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - Apple Support

Force Quit Safari ( command + option + esc keys).Then restart Safari holding the Shift key. If you still have problems Empty Caches (Safari menu > Preferences > Privacy > Remove all website data. (This will also remove history if you do not want to remove History open Safari Preferences > Advanced and check mark “Show Develop Menu” then choose “Empty Caches” from Develop Menu ).

Then go to Safari Preferences > Extensions and check there. If there is an extension delete it.

If the problem persists download and run MalwareBytes. Malwarebytes was developed by one of our own colleagues here in ASC and is about the most proven anti-malware software for Mac.

I have the same. But it’s in my calendar app.


Nope, you have a different (common) scam. No virus, no hacker, all from a calendar subscription.


Some website pr some pop-up ad offered a “do you want alerts/notifications?”, and that offer was accepted and a subscribed calendar was added and now you have alerts in your calendar.


A subscribed calendar that you no longer want.


As you no longer wish this subscribed calendar, you will want to remove it.


How to remove the calendar differs slightly, based on whether you are on an iPhone, iPad, or Mac.


On an iPhone on iOS 13 or later (iOS 14.7.1 is current) tap the calendar button at the bottom of the display, find the subscribed calendars section, and remove the unwanted calendar by tapping on the information ℹ️ button on the right of the rogue subscribed entry, scrolling down, and selecting the deletion.unsubscribe,


On iPad, the button to view the list of calendars including the subscribed calendars is in the upper left. Tap that. Find the added subscribed calendar entry, tap the information ℹ️ button to the right, scroll down, and remove it.


On a Mac, find the rogue subscribed calendar in the calendar list, control click on it, and select unsubscribe.


Here's a list of some of the common scams:

If you see the word “virus” or “hacker” anywhere in advertising or pop-up ads or calendar alert text these days, expect it to be a scam or a sketchy tool, and not actual malware. Calling telephone numbers can be spoofed, sending email addresses can be spoofed, and some advertisers routinely, well, lie.
