Troj/Mitglie-DQ is a Trojan for the Windows platform.
When first run Troj/Mitglie-DQ copies itself to <System>\msnethlp32.exe and creates the file <System>\msnethlp32.dll.
HKCR\exefile\Shell\open\command\
"<System>\msnethlp32.exe\" -run \"%1\" %*
This will result in the Trojan being executed every time a user runs an EXE file.
Troj/Mitglie-DQ listens on a randomly-chosen port. Anyone connecting to this port will be able to download files to the infected computer and then execute them, or use the computer as a proxy via port-forwarding or the HTTP "CONNECT" command.
