Trojan.Dropper.Generic is Malwarebytes’ generic detection name for Trojans that drop additional malware on an affected system.
Downloaders and droppers are helper programs for various types of malware such as Trojans and rootkits. Usually they are implemented as scripts (VB, batch) or small applications.
They don’t carry any malicious activities by themselves, but instead open a way for attack by downloading/decompressing and installing the core malicious modules. To avoid detection, a dropper may also create noise around the malicious module by downloading/decompressing some harmless files.
Downloaders often appear in non-persistent form. They install the malicious module and remove themselves automatically. In such a case, after a single deployment they are no longer a threat. If for some reason they haven’t removed themselves, they can be deleted manually.
More dangerous variants are persistent. They copy themselves to some random, hidden file and create registry keys to run after the system is restarted, attempting to download the malicious modules again. In such cases, to get rid of the downloader it is necessary to find and remove the created keys and the hidden file.

They may also be installed without user interaction, carried by various exploit kits.
