Selected viruses, spyware, and other threats: sorted alphabetically
Dropper is a simple executable file. Its only function is to install virus into memory or attack files with a virus. Dropper is usually used by the author for sending a virus into “wild”, i.e. it is a zero virus generation. In case of polymorphic viruses the dropper in most cases does not contain a polymorphic decryptor but only the bare virus body.
