The original file will then be deleted.
The DLL file infects the IEXPLORER process (opens it with all possible privileges and writes its data to the address space). IEXPLORER then attempts to download other files via the Internet and launch them on the victim machine.
Programs classified as Trojan-Downloader download and install new versions of malicious programs, including Trojans and AdWare, on victim computers. Once downloaded from the Internet, the programs are launched or included on a list of programs which will run automatically when the operating system boots up.
