Seems to be a driver for Alcohol 120%
Don't view and open disks on DVD -ROM device, is tetected like a rootkit
Its Installed by Deamon Tools and can stop your system from booting if the driver conflicts with another device

It may be from Alcohol 120% that creates a virtual SCSI CDRom drive

Gehört zu - Part of: Alcohol 120%
Yes, looks like Alcohol 120% virtual drive driver. After forced removal Alc.120% stopped working - after reinstall vax347s.sys appeared again. So i'm positive about that.
Relates to SCSI Controller and/or virtual optical drives for Alcohol 120%, May be unnecessary if Alcohol is not installed.

A clean and tidy computer is the key requirement for avoiding problems with Vax347s.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time.
