Blue Screen

Hello

I am having trouble with a blue screen. My Avast says it stopped some threat and that no further action is needed, but then it went into the blue screen and that is where I am at now. Can anyone help me? This is my first time using Avast. Please, I have so much work to do and I am stuck with a blue screen. It will come on and as soon as I get started it will pop up to the blue screen again. Any help will be appreciated. I have a picture of the screen and the treats if that will help.
Thanks
Ms Ann
