What is 1UnHooker.sys?
VirusTotal only has McAfee-GW-Edition say Heuristic.BehavesLike.Win32.Rootkit.H
.
Looking into this further, it seems to be Tizer� Rootkit Razor and that file is Tizer File System Driver.
All that is hidden under the name X-Wire Technology and a fake service called Windows Installer.
