1. If the system is not booting normaly anymore (BKA/GVU trojan) Any other problems it is highly suggested that you load windows in safemode
But with No details or any more information to the issue you can only suggest steps in hope to resolve and eliminate the issue.
While resolving the problem would be way easier if proper information would be provided.
I was waiting for a reply of Kona but without any reply there is either no help wanted or the problem has been solved.
Also problems like these would not be an issue if proper protection would be used, this may sound harsh but in most cases it is the truth.
I have repaired enough computers in my years where trials had been installed that had run out of testing time for years where no updates had been done, or no users with no protection software at all, since it seemed to slow down the computer, therefore it had been easier for certain individuals to uninstall and run the computer without it. With breaking results.
