The later Trojan-Downloader:W32/Dluca.T variant silently installs itself to system. It copies itself as files, with the names infwin.exe and infwin-uninstall.exe, to the Windows System folder and adds a startup key for the infwin.exe file into the System Registry. The trojan-downloader then deletes the file it was started from.
