Hi I looked in file manager and couldn't see much in phone storage/download except a lot of files which are in an unsupported file format and just appear as a very long list of seemingly random letters and numbers with a blue '?' on a file icon adjacent to them.

Interestingly in phone storage I also found a folder called GoAdSdk containing 2 further folders called 'advert' and 'config'. I clicked on 'advert', got 'cachefile' and 'cacheimage' in each of which are listed a number of unknown files some simply numbered between 4-6 digits but with further files listed below titled BaseResponseBean followed by the individual file numbers. So listed under 'cachefile' for example we have a file named 107508 and further down the list we have a file named BaseResponseBean-107508 and so on.

I also found a GOSMS folder even though the wife doesn't have Gosms on her phone.

I heard that Go apps can cause some of these dodgy adverts but have no idea if this is true.

Shortly after this, when we swiped to unlock the phone again and have another look, a small advert once again appeared directing her to a playstore app.

Searching for 'com.android.share.back' in file manager yielded nothing by the way. Also, touching/holding the adverts doesn't show us where they're coming from as we've been led to believe it should on Android 5.1.
