I have a 2 in 1 tablet PC. Windows 10. Brand is Nextbook. All of a sudden I started to get an error message with a lady's voice saying my computer has been infected by spyware and all of my sensitive info has been compromised. Please help me diagnose and identify if there is a virus. I have downloaded Malwarebytes and it found no threats, but I'm not sure if it's safe yet. Thanks in advance.
