Running in safe mode, cant install Norton
About a week back my Mcafee expired. I recieved a virus almost immidiatly. My computer palyed random music, voice notes, commericals, just the audio though. I went into the task manager and managed to find the right program and ended that task. I just bought Norton today, and know that I needed to delete Mcafee to install Norton. So I deleted Mcafee and was prompted to restart my system. After restart a blue screen came up and my computer would not start. It restarted, i logged into my user name, and a few seconds later after everything had loaded it went back to that blue screen and shut off. I've tried to install Norton in every possible way. I tried in safety mode, and all the other options i was given. How can i fix this and run my computer normally, and install Norton?
