BadBoy7: Without actually seeing what it is saying, it sounds like Malware has infected the machine.
If you cant get on the internet then you have problems, unless you can download onto a flash drive and plug that in. You need to run Malwarebytes' Anti-Malware. If that is not an option, try to take anything important off the pc and do a system restore. Personally i would take it back to factory settings and start fresh.
This is just another reason not to use Windows lol
