The detection for Generic Downloader are for several specific trojan variants, so this description is meant as a general guide.牋 This detection is for trojans which are intended to retrieve and execute files from a remote server.?This file will then be automatically executed on the infected machine.?The nature of the remote file may vary. As the presence of these trojans and remote files are discovered, sites hosting these files are frequently taken down, so the downloading may cease to function as expected.?This may result in empty, 0 byte files or HTML error messages being downloaded instead, or the remote file simply not being downloaded at all.
As new trojans are frequently added to this detection, users are recommended to use the latest engine/DAT combination for optimal detection. Variants are likely to be packed with a PE packer, so enabling the scanning of compressed files will also provide optimal detection.
