No, brand new 16 gig SD card, formatted in camera with a load of photos on it and nothing else, inserted into a USB reader. ( maybe I shouldn’t have used a reader from Poundland) 
Interestingly the Additional text file refers to AVG disabled.
I uninstalled that when it up-issued to 2013 edition, as it was clashing with something and crashing the PC in a big way.
That needed a ghost from a previous image with AVG 2012 still on it. I hadn’t realised what was causing the problem at the time, but as soon as it updated again to 2013, windows was seriously trashed again.
Fortunately I could still get at ghost from Safeboot that time, so a second image replacement offline and uninstalled AVG before re-connecting…
I then replaced it with AVAST which seems to have caused issues on two separate occasions. I wonder if there is a bit of AVG left that it has clashed with.
I ran CCleaner to try and flush anything out at the time and MalWare bytes has never found anything yet.
I did have Lavasoft Adaware on the at one time, so I wonder if there’s a bit of that lurking somewhere as well.
I do need some sort of AV program, so was wondering about Mcafee, as I’m on BT internet, so it comes free.
Additional text file attached, if you get the chance to peruse out of interest
Many Thanks again for your time. I presume by your username that you’re too far away to buy you a beer.
