I have installed McShield and got its log:
MCShield ::Anti-Malware Tool::
http://www.mcshield.net/>>> v 3.0.5.28 / DB: 2016.2.21.1 / Windows 7 <<<

=> Suspicious files : 2/2 renamed.

I have also uploaded the suspicious file volumeInformation.exe to virustotal.com and It says... to be more precise, 4 Antiviruses (Antiy-AVL, E SET - NOD 32, Invicea and Jingmin) from 57 in total say it is a Trojan.
As I understand MCShield neutralized it only on a flash drive. What can I do now to remove the Trojan from my Windows 7 (64 bit) system?
