Defogger?

[MobileTechie]

In this thread: http://www.theeldergeek.com/forum/index.php?showtopic=41997 they recommend the user runs an app called defogger.exe as part of a malware cleaning process.

By the look of it the users HJT log is clean so I'm wondering if it's some rootkit revealing tool?

I couldn't find much about it.

"If you are are using a CD Emulator (Daemon Tools, Alchohol 120%, Astroburn, AnyDVD) be aware that they use hidden drivers with rootkit-like techniques to hide from other applications. When dealing with a malware infection, CD Emulators can interfere with investigative tools producing misleading or inaccurate scan results, false detection of legitimate files, cause unexpected crashes, BSODs, and general 'dross' which often makes it hard to differentiate between malicious rootkits and the legitimate drivers used by CD Emulators. Since CD Emulators use a hidden driver which can be seen as a rootkit and can interfere with investigative tools or cause other problems, it is recommended that they be removed or disabled until disinfection is completed."

It looks like it stops cd emulators.
