The wife's been getting pop up adverts on her lock screen for a while and we've been trying to work out what's responsible. She recalls clicking on a Facebook suggestion some weeks ago and a gambling advert appearing on her screen. This then kept happening on her lock screen until I removed a couple of apps and the full page ads stopped. She then started getting smaller adverts almost like large notifications in white text in a black box for various apps like emoji keyboards which seem to direct her to apps on Google Playstore. Sometimes these adverts disappear after a few seconds and sometimes they remain after she's swiped to unlock her phone.
On checking her Lookout AV history, I found a download called 'com.android.share.back' listed about 2 weeks ago. I looked in manage apps and can't find this listed anywhere so I'm wondering if this is the cause of these latest annoying adverts or whether they're to do with Google Playstore. We'd like to stop them but can't find a way to do it so can anyone assist please?
TIA as always.
