Trojan virus text from Apple security
Today a friend rec'd a text on her iphone that appeared to be from Apple Security saying "important notice-your device is currently infected with a Trojan virus. Your phone's memory is already having 17% of damage. Prompt action is required, otherwise your device will become defective and all your data including accounts, photos and payment data will be available to third parties. Immediately install the trusted app from the App store to remove the virus and secure the device."
I advised her not to do anything, thinking it was a scam--was I right to do that?
