My parent comment is based on real events. A relative did actually install an antivirus and a bunch of other crapware on her Android phone. The thing was so agonizingly slow I just didn't understand how she used it at all.

But that phone ran an Android version from before Google started seriously cracking down on apps running background services without restrictions. Modern Android is pretty robust in this regard — with a few exceptions, an app can't run in the background without showing a notification ("foreground service" is how the API calls it).

There wasn't much self-blame. She just assumes that technology is like that, complicated, unreliable, slow, and full of magic. It's nice when it works, but not a huge loss when it doesn't. She would also indefinitely quietly put up with things not working until someone asks and finds out, then I'd fix it.
