Dear ESET Support Team,
I am writing to bring to your attention a potential false positive detection that I have encountered with ESET antivirus.
Today, ESET's real-time file system protection flagged the file ManagedFusion.Rewriter.dll, located in the directory C:\Models\AppTasking\CSharpModel\web\bin, as a variant of MSIL/GenKryptik_AGen.AMA Trojan. The detection action taken was disinfection by removal. The user affected was IIS APPPOOL\ASP.NET V4.0.
I would like to emphasize that this file is a legitimate component of my .NET applications, and it has been in use for over a year
I received the following information from the ESET detection log:
Detected Object: C:\Models\AppTasking\CSharpModel\web\bin\ManagedFusion.Rewriter.dll
Detection Name: MSIL/GenKryptik_AGen.AMA Trojan
Detection Action: Disinfected by removal
User: IIS APPPOOL\ASP.NET V4.0
Additional Information: A event occurred while the application attempted to access the file: C:\Windows\System32\inetsrv\w3wp.exe (5B26086A46E6EB02C8F5352CFC3D50A3D111ED06).
File Hash: A5DCF7435405046A0F4CB87D5980A1E7B33482A9

Considering the above information, I strongly believe that this detection is a false positive. I kindly request your assistance in reviewing this case and updating the virus definitions accordingly to prevent further disruption of my legitimate applications.
Thank you for your prompt attention to this matter. I appreciate your dedication to maintaining the security of ESET users.
Sincerely,
Marco O.
