I tried to do what you said but we can't open any internet browsers:(

Well, I don't know what to tell you, except, please do not plug in any usb device into that computer. Without any type of log to go by, it's difficult to say what the machine is infected with. If it's an autorun of some type it will spread to any usb devices plugged into it.

Maybe someone else has an idea on how to get browser open.
