Okai, so I don't know exactly where to start, but it all started when I was looking for a live stream on an NFL football
match. I had been looking around different sites with no luck, when I suddenly saw UAC popping up about "Microsoft inc (etc)"
want to install some software on your pc. I was like weird, I didn't see anything in the Windows update earlier, and closed
it cause I didn't wanted to do it right there. It popped up Again and I closed it, it kept going on for a while until it
randomly stopped. 15 min later it popped up Again, and by ACCIDENT I clicked yes. Nothing happen, and I whent to bed later
that night. The Next day when I started the pc it came up with Black desktop saying "ERROR ERROR ERROR YOUR DSK(I can't
remember exactly what, but and didn't get time to take a Picture cause it restarted) This time it came up with a Black screen
agian. I was like, Ehm, what the hell? And then my antivirus popped up, saying it had caught a trojanhorse in Windows boot
files, and the anti virus whent on deleting the virus (I had Microsoft essenstials.) It asked to reboot so it could get the
job done. When it was starting up Again, all I got was a Black screen with a _ blinking in the upper left corner, and since
that I haven't been able to start my pc, so I installed a not pre-release of Windows 8 on my E: HDD so I could try get some
support. At the start I was thinking of re-installing Windows, but I've lost my CD key, so don't know exactly what to do.
