This is the latest I could find at www.symantec.comI've not run into, nor heard of it, until now:
The Little_Red virus is a .COM and .EXE file infecting virus that specifically targets the COMMAND.COM file and uses encrypting when storing itself within a file. While this virus is active in memory, it will spread to other files during any attempt to execute a file or whenever a DIR command is issued. In the case of the DIR command, all the files in the current working directory become infected.
In attempts to hide itself from the user, this virus uses size stealthing whenever the DIR command is issued.
On either December 16th or September 09th when the systems date's year value is greater than 1994, the virus will trigger at a random time and play a song.
