Take it back to the shop and get a refund, Norton system works is responsible for so many pc problems you are better off without it.
I could rant on about this programme, I don't know how many pc's I've had to format after people have installed this programme, imho, get rid of it.
What were the features in System Works you need? there are plenty of freeware products out there that do a better job, list your requirements and I'll see if I can point you at a few.
