Hi there,
Is it possible this could be some hackers that have hacked into the actual Windows 8 database, if more than one users are receiving the same black screen error?
Search Protect is by Conduit, which is a well known virus that has been going around. Is it possible for you (or someone else) to get Microsoft to check for a breach in their database?
I would recommend anyone who is having the issue to follow this steps after managing to boot into their computer.
Remove Conduit Toolbar and search.conduit.com.
