The Gmer log tells it all, the infection first started when i opened an infected file and it ran a "Yesseaches" browser hijacker, and then my screen blackout so i quickly pulled the power because i thought it was ransomware in the process of encrypting. When i tried to start the computer, it was very slow and it took around 9 reboots to finally get it up.

 

I have ran Hitmanpro, Adwcleaner, Roguekiller, JRT, Malwarebytes, aswmbr, tdsskiller all without any luck.

 

The Gmer has removed around 5 hidden .sys files and services that where not there before, and now im just worried about that "hidden mbr code" that was not there before.

It's probably a driver issue.

Refer to this page.
http://www.tomshardware.com/s/critical+structure+corruption+windows/

Is there more to the message such as Critical Structure Corruption (Win32kfull.sys). <- the file may be different.
Let me know.

Please download MiniToolBox to Desktop and run it.

Check mark the following boxes:
  • List last 10 Event Viewer log
  • Click Go and copy/paste the log (Result.txt) into your next post.
  • Note: When using "Reset FF Proxy Settings" option Firefox should be closed.

I dont know if there was more to the error, but there is a memory.dmp in my windows folder. Do you need it for anything? its around 800 MB.

 

I also attached a cbs.log, i ran a sfc /scannow and it could not fix some errors.

I downloaded a blue screen reader, and it was caused by "ntoskrnl.exe"

 

I have attached a report created that you might find helpful.

 

But as i know, there was only the "Critical Structure Corruption" on the actual bluescreen.

3 Possible reasons for this BSOD.
http://www.pcadvisor.co.uk/how-to/windows/how-fix-ntoskrnlexe-bsod-3613143/

I suggest you start a new topic in the Windows 8 Forum. An expert with that operating system should be able to help you better that I can.
http://www.bleepingcomputer.com/forums/f/209/windows-8-and-windows-81/

I will leave this topic open for 6 days. If you need to return please do.
