Hi

Have you got a ethernet cable so that you can connect your daughters laptop to the internet
via the ethernet slot on the laptop

if so you could then hopefully get on the internet and check that all you windows updates are up to date

to do this go to

start
programes
windows updates and except all of them and hopefully it will offer you internet explorer 8 or 9 which is the latest ones

maybe this will sort it for you

good luck
