My laptop won't boot up. It keeps going to step 3 of 3 for Microsoft setup. There was a huge virus that has got into our whole school system, over 3,000 computers. I had used my memory stick to take my lesson plans home and work on them. I had no idea that it would transfer to my laptop. It isn't a school issued laptop so I am going to have to get it fixed myself. Is there anything I can do before spending money to get it repaired?

first thing first, do you have an antivirus, if so what on, and are you the adminerstrater of the network, and do you have microsoft office or any major software like that

This laptop was a gift. It came from Best Buy and I hadn't put anything on it yet. I think it came with some protection but not real sure. It said Vista on the sticker. I really didn't even get to use it much!! The cd's for start-up weren't in my bag. So I don't know what to do. I am not the administrator at my school.
