Carole - I stuck my head in at local W.H.Smiths this afternoon and the computer magazine is PC Answers, July 2007 Issue (UK magazine). It has Acronis True Image 8.0 on its cover disc. It also has a partitioning tool and a couple of other useful programmes.
I would strongly recommend getting True Image (definitely worth the £5 or so for the mag) and take a mirror image of the system drive before you start making big changes or reinstalling software.
If you have such a backup safely stored it doesn't take long to restore your setup if you ever get a virus problem. It just overwrites the crud with a working copy of the system.
Quack!
Geoff.
