We believe a family member is being stalked by a very nasty/cunning/smart ex. He turns up where she is too many times for it to be coincidental and appears to have access at least to her call log as he definitely knows who she has called. She has an iphone and an ipad and has been using Imessaging. She changed her phone but can not change her number (for valid reasons). She has disconnected from any icloud backups. Police and various IT experts have been unable to help her. We are now advised that it is very easy to put something on someone's phone to track them if you know their phone number. Is anyone able to help with a) how to find malware on her devices and b) how to block it happening. Would Whapsapp or Snapchat or something else be more secure?? Thanks in advance
