"Suspicious Activity Might Have been Detected" malware in Safari or other browsers Did you navigate to a page that produced a popup that says (among other things)...

Suspicious Activity Might Have been Detected

...and then asks you to call a toll free number? As you might have guessed, this is a scam, and seems to be going around for a while now. It happens on iOS and MacOS, and in different browsers.

How do I fix it?
Here's the solution on iOS/Safari:


Close Safari
Open Settings
Look for the Safari settings, click it
Click Advanced (at the bottom)
There is a setting for JavaScript, turn it off
Close Settings
Open Safari
Close the message box if it is still open
Click on the "show me all the web pages" icon in the lower right (whatever it's called)
Close the page in question
Go back to Settings and turn JavaScript back on


All done!
