Detection name of dropper actually means absolutely nothing and it will be indifferent most of time. It maybe detected as ANYTHING.Malware or as Trojan.Downloader or as IDontKnowWhatIsItMalware, which only mean AV will kill this file because of it presence in signatures no matter how it named. Once dropped malware can extract/download additional components which will be detected differently. The only meaning of name comes when this specified malware need EXTRA attention on cleaning like for example Sirefef or Alureon in past when AV will execute it scripts specially written for EXACTLY this malware, so AV maybe unable to cleanup malware detected with improper name. Everything else can be killed by simple removing file and performing standard generic registry cleanup. Also *proper* naming required for malware collectors. For end-user in most cases it means nothing.
