Trojan-Spy:W32/Banker.GMH is also known as  Trojan-Spy.Win32.Banker.gmh.
This Trojan steals banking information and has the capability to update itself.
 Upon execution, this malware drops the following file:
 
 -  %windir%sflash.dll - detected as Trojan-Spy.Win32.Banker.gmh 
  
 
Note: %windir% is by default, C:Windows.
It checks to see if iexplore.exe is running. If it isn't, it will run IE in the background and will inject the dropped DLL file as a Browser Helper Object.
It creates these auto-start registry keys:
 
 -  HKLMSoftwareMicrosoftWindowsCurrentVersionRun
Shockwave Flash = Rundll32.exe sflash.dll,Init
  
  - HKLMSoftwareClassesCLSID{32C18258-23D0-41b0-A87D-2672ABFB5366}
  - HKLMSoftwareClassesCLSID{32C18258-23D0-41b0-A87D-2672ABFB5366}InprocServer32
  - HKLMSoftwareMicrosoftWindowsCurrentVersionExplorer
Browser Helper Objects{32C18258-23D0-41b0-A87D-2672ABFB5366}
  
 
It downloads the following file:
 
 -  http://69.6.202.56/.fp/[REMOVED].exe
- Trojan-Spy:W32/Banker.HYN  
 
It saves the file as %temp%aol92.exe and executes it.
Note: %temp% is normally C:Documents and Settings\Local SettingsTemp.
