Trojan muldrop. Install WinpkFilter driver and drops actual rootkit named srenum.sys (playing around similar name of legitimate serenum.sys). Driver set on autostart. Can't tell anything else right now because test system died with help of this rootkit installation. However system is still accessible through Safe Mode.

edit: srenum.sys does not work without first driver (it communicates with it). Also drops msrun.exe to system32 folder. Find attached. Purpose - parsing likely config file (\\SystemRoot\\System32\\setie.txt) and starting additional processes.

Overall - this is backdoor with driver agents components. No rootkit activity found. All malware components can be removed without using any third party tools including antiviruses.
