You get TROJ_DLDER.A with file sharing apps
If you download Grokster or Limewire you get more than you expected.

This trojan program is also installed along with two file-sharing programs, Grokster 1.3.3 and LimeWire 2.0.2. Both programs are downloadable from the website
http://www.grokster.com. Grokster is downloaded from the *US-site* as SETUP.EXE and LimeWire as LIMEWIREWIN.EXE.
Upon installation of these file-sharing programs, TROJ_DLDER.A is also installed on the computer without the user's knowledge. Aside from the file DLDER.EXE in the %windows% folder, a hidden folder named "explorer" is also created in the %windows% folder. The hidden folder contains a file named EXPLORER.EXE.
If you use these file sharing apps it might be wise to do some reading and investigating.
