Tarq - thanks again - I had assumed it was just the 'demise' of 7.5.
As I posted, I am using Avira at the moment so I am taking a 'rain check' on AVG TFN. I may return. So far Avira looks good if anyone else would like to comment? Scheduled scans etc, missing from Avast as Keef says. 24mb download though.
ParaB - thanks also. I 'fixed' the problerm with a sys restore, but good to know the fix. The 'support' for the Free version is pretty well (understandably!) non-existent. The forum is the only real way to get help and the mods are 'non-AVG' bods but helpful. They walked me through a reset of permissions in the reg (which had been a 'hint' from other Googling) which could have been blocking the reg key creation, but that knocked out Mrs B's User profile on the machine (now restored).
Fun, innit?
Edited for emabarrssing spelling mistake
