I have an Android 4.4 phone which I have just been using to interrogate
car bluetooth diagnostics. It hasn't been used as a phone and has no
credit.

Today we took it for a trip attached to the windscreen to record the
journey across Wales and check error codes. On reaching home, it
suddenly popped up a message asking me to thank the person who had
invited me to join "Swift WiFi", with an app of that name installed.

Research seemed to show that it wasn't something I wanted, and a couple
of other apps had appeared that I had never heard of.

I installed Malwarebytes and it found 4 things that all seemed to be
part of genuine, known apps, so I went looking for another AV app. I
installed Sophos. This found a bunch of weird files of "Low Reputation
Apps", some of which seem to be in folders named after apps I have never
installed. An app, which I am testing for someone and which I know to be
safe and as yet unreleased in the wild was also identified as Low
reputation.

I'm alarmed that something or someone seems to have been able to install
something which messes with wifi settings and possibly installs other
things but also by the security applications.

Has anyone got any insight into all this?
