Turned on the laptop this morning for an early start - but it had crashed and the C Files gone. Fortunately I was able to get it back in a 'new computer' state. Couldn't get the internet connected, but my eldest son came to the rescue a few hours later and got it all back into action. Got the pro AVG going again as well.
But last night for some inexplicable reason I had loaded all family pics and a few selected pics into my Google files.
