You had an powerfull TDL4 rootkit variant know to us as Pihar rootkit. They are also know as MBR Rootkits. It lives outside of operating system, creating his own file system and do peyload into system.

Rootkit has been removed. Your system looks clean.
It is necessary to remove used tool for an some post-cleaning.
Download “Delfix by Xplode”
Run the tool … Check the boxes …
[] Remove disinfection tools
[] Purge System Restore
[*] Reset system settings
Click on “Run” button.
I don’t need DelFix log report.
I recommended to keep Malwarebytes AntiMalware and to use MCShield if you will.
You may download MCShield from one of the following links:
MyCity - Official download link
Softpedija - Mirror download link
It will prevent infection by computer via USB flash drive, mobile phone or any other memory card.
And not only will prevent infection, but it will immediately clean flash drive, memory card or external HDD.
