Troj/Dloader-KM is a downloader Trojan.
When first run Troj/Dloader-KM copies itself to the Windows system folder with a random filename and runs itself on startup by adding its pathname to a new registry entry under:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
The new registry entry will have the same name as the Troj/Dloader-KM executable minus the extension, so for example if the Troj/Dloader-KM executable is named random.exe, the following registry entry is created:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
random
random.exe
Troj/Dloader-KM tries to download a CAB archive from a remote location and install/run its contents.
Troj/Dloader-KM injects code into new hidden instances of explorer.exe, calc.exe and packager.exe.
These processes prevent each other from being terminated and refresh the registry startup key mentioned above, in order to prevent its deletion.
