Yeah I have been looking a bit more and it appears we have MS Works which is, as far as I understand, free to use because it has ads. My wife did ask whether it is compatible with Office – I assume it is?
I have installed Chrome as it is my preferred browser.
I will spend a bit of time looking to see what is bundled in the way of firewall etc too – as said above, I don't want to ram it full of pointless stuff – it is simply one of the cheapest laptops I could find with a 500gig HD (£400) so I can store all my music and pictures on and for my wife to do a bit of browsing (I tend to do mine at work/on my iPhone).
But I will certainly be looking at the AVG and GIMP suggestions. I appreciate that GIMP won't be as flexible at Photoshop but if I ever need to do any more than basic retouching I can use CS4 at work anyway.
One question re Picasa if anyone can help… It seems to automatically rotate images within the programme, but if I then open the file outside of Picasa they are still the wrong way around. The question is – how do I actually rotate them????
