Please can Alan Binch help me sort out a rogue install

Hello Geoff,

Thank you

Built a nice new NUC machine and decided I wasn't confident in the MS offering, so clicked the "Plus" sign on my laptop's install of "AVG Free with Zen"  expecting to download and install exactly the same product for this machine.
Apparently not the case!
It seems I have installed the full version on a trial basis.
I absolutely do not want trials of anything!

I'm also alarmed to see that my laptop now also seems to have been altered without my consent and the same trial installed.

This also begs the question will the same thing have happened to my Vista PC (I cannot access it at present since it shares the same monitor with my NUC machine.

Please Alan, help me to sort out this mess without further interjections from the subcontinent!
Thanks.
