Since each one has its own removal or mitigation procedure, I don't expect a one size fits all solution short of "format and reload then restore from your backup."
Also share how this invaded your PC.

So I was recently the victim of a decryption virus and when I tried to fix it and restarted my pc It started windows then the login screen was different, the user acct icons were white rectangles, the power option icons in the bottom right were gone so a simple shift + restart for boot menu was out of the question.
I have the ability to enter my pc by logging in but it heads to a black screen with very few options, I can open task manager by doing ctrl alt delete and clicking the option though its in the same language, which is rectangles and triangles and other odd things. I was wondering if there is a way to hard reset by just messing around with the pc components or a way to fix this.my pc is a asus x550c with windows 8.1
