W2K.Stream virus was discovered in early September 2000. The virus was created by Benny and Ratter of the 29A virus group. This virus is a proof-of-concept virus that utilizes NTFS streams and has received much attention. It is a new subclass of the traditional companion virus and is now being referred to as the "Stream Companion" virus.
W2K.Stream virus only infects files on Windows 2000 using NTFS, and only the files in the same directory. The infected files will become 3,628 bytes in size regardless of the original file size because the original host file is replaced by the virus and stored in a different stream.
As of September 7, 2000, Symantec AntiVirus Research Center has received no reports of this virus in the wild, and it is considered a very low threat.
