N/A. Downloaders are not viruses, and as such do not themselves contain any method to replicate. However they may themselves be downloaded by other viruses and/or Trojans to be installed on the user's system.
Many of these additionally are mass spammed by the author to entice people into double-clicking on them.

All Information
Overview -
Downloaders are designed to pull files from a remote website and execute the files that have been downloaded.
As it is trivial for the malware author to modify the Downloader to refer to a different website or web address, McAfee write detection routines for Downloaders which as a general rule do not include these strings in the detection routines.
This allows McAfee to write more generic detections for these threats and to proactively protect customers against future minor variants.
Therefore it is not possible to guarantee which website and/or port is being communicated with.
Also, as the website being communicated is normally controlled by the malware author, any files being downloaded can be remotely modified and the behavior of these new binaries altered - possibly with every user infection.
