Hi, my browsers keep crashing. I tried to download it and install them again with no sucess. Trying to run spybot and malwarebytes and they just dont start. All happened after a program asked my authorization to run. I said no and it insisted. After I closed the window, my computer restarted and the problem appeared. Normally crashes when Im trying to write on facebook, msn ou skype and it gives a message saying that it encoutered a problem with a script (resource:///components/nsPrompter.js: 466). Can you help me? Thanks.
