My computer got a malware virus today, my son has been trying to fix this problem. He ran a registry scan in safe mode because it would'nt let him connect to the internet. After he ran the scan he rebooted and it seemed to take away one of the pop ups that had been appearing. He restarted so he could go into safe mode again and it wouldn't load, nothing but a black screen. We have no idea what has happened , if you could help us in any way it would be greatly appreciated.
