Adobe Gamma Loader.exe Detected as Trojan.Gen.X

Created: 21 Sep 2012 • Updated: 24 Sep 2012 | 18 comments
This issue has been solved. See solution.

This morning we had a fair number of machines that detected Trojan.Gen.X for the Adobe Gamma Loader.exe (file path on XP:  C:\Program Files\Common Files\Adobe\Calibration\Adobe Gamma Loader.exe).  I think the systems are all running Adobe CS 3 but am not 100% positive on this.  Is this a legitimate detection or a false positive?

On Google + others running different versions of CS or other Adobe products are getting this as well.

Prachand, I will try to do this if I can get it.  SEP Policies have been deleting it on a lot of machines, though we may have some different groups with different policies.

Submitted to Symantec.

We are getting quite a few machines reporting this.  Some running CS3, CS5 and some running Adobe PS Elements !

It is part of the Adobe screen gamma calibration tool.

I added it to the centralized exception policy, then restored the file backup in the quarantine.  Submitted the file to Symnatec support, and here is the result.

Will leave in my exception policy until I can get word from Symantec that the detection issue is resolved.

Adobe has always been and will always be vulnerable.
If possible swap if you do not just put the SEP always on alert with adobe
There are vulnerabilities and exploits that are created to always attack with this type of application.
take care

Support indicates the fix should be in defs r17 from today, or in tomorrow's base certified release.

Hope that helps you out.

I'm leaving my centralized exception entry in until Monday to be sure.

I have a home copy of SEP provided by my employer. it detected adobe gamma loader.exe as trojan.gen.x yesterday evening. I deleted it and ran a full msanual system scan.

SEP found another file that it identified as trojan.gen.x:


Is this a coincidence, or has SEP found two real trojans?

Not being very versed in these deep computer detail, might it be a restore version of the same adobe file?

Hello ragenkagen,

Please see this thread:

There was a recent False Positive with a file of this name, but that has now been corrected.

With thanks and best regards,
