I gotta second Joey_Batch_File reccomend for an image. I live in E. TX and am familial and neighboorhood tech support. I have a couple of seniors in the neighborhood who kept opening virus mail and asking me to come clean their system. After the 3rd time I took the husband to Hastings and bought Norton and did a clean install of their system (including most used proggies). Redirected My Documents to a secondary partition and pointed mail storage to D: as well. Then made a Drive Image of the c: partition.

They are now well trained on making sure that any data they care about is on D: and if they have a problem (virus or otherwise) we just run Drive Image and recover their system, run Live Update and they are back on the 'net for good or ill.

Good luck!
