Hey everyone a few days ago, I got this Malware Defense virus, and all the lovely trojans along with it. After finding a guide using malwarebytes and studying on this thing, I removed it and all. And Malwarebytes said my pc was clean yet after the restart, Firefox wont work, just gives Drwatson error when I try to open. So I run this program called rkill from the guide to kill the rootkit and open new explorer.exe, and all is fine, I scan with Malwarebytes again and it shows Rootkit.TDSS is hiding in registry HKEY_LOCAL_MACHINE\SOFTWARE\H8SRT. Yet when I go into the registry in normal or safe mode the registry key is not there?! This is a repeated process every time I turn my computer on. I have included the log here from safe mode, I have other from regular if its wanted. Some help on how to finally get rid of this is really appreciated! Thanks.
