Adload virus on iOS device
My ISP told me they've registered unwanted activity in my network, and appearently I've got an Adload virus on one of my iOS devices (either iPhone 13, or iPad Pro) which I can't seem to get rid of.
I've already installed Avast (from the App store) and I've reset both my iPhone and iPad and so did my husband. I've also changed the Wifi password just in case someone outside of my family is using it.
Now they've informed me again there is an infection in our network and they're basically threathning us to shut down their service for us.
I really don't want to go through the procedure of resetting all my iOS devices again. I got shut out of my offices Microsoft 365 and lots of other 2 step authenticating stuff went completely haywire. Took me days to get back up and running.
Today I've visited an Apple dealer and they said it is basically impossible to have a virus on your iOS device.
My ISP is being very unhelpful, they tell me to download a virusscanner for iOS (which doesn't even exist) and that's it.
So:here's my questions:
How to get rid of this thing without having to start all over again on my iPhone etc
And: does anyone know of an app which would cause this? I'm only using app store apps and this problem has been going on since december 2023... we're pretty decent surfers, no obscure websites because Avast is supposed to protect us from that.
iPhone 13, iOS 17
