Kernel Security Check Failure

I have been getting a blue screen with a frown face with the following: "CYour PC ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you. If you'd like to know more, you can search online later for this error. KERNEL_SECURITY_CHECK_FAILURE

What do I do about this?
