About Trojan-Droppers

A Trojan-Dropper is a type of trojan that drops different type of standalone malware (trojans, worms, backdoors) to a system. It is usually an executable file that contains a other files compressed inside its body. When a Trojan-Dropper is run, it extracts these compressed files and saves them to a folder (usually a temporary one) on the computer.

In many cases, Trojan-Droppers also drop and executes to display games, images or messages, which serve as decoys to avert attention from malicious activities.

For representative examples of Trojan-Droppers, see the following descriptions:

Note

Some Trojan-Droppers extract components directly to memory and activate them there. In this case anti-virus software is not able to detect dropped malware, so detection of the whole trojan dropper package is added.
