Anarchy.666
This is a dangerous memory resident parasitic stealth virus. It hooks INT 21h and writes itself into COM and EXE files that are closed. On infection it writes itself into the middle of COM files (if there is the area with the bytes of constant value), or overwrites the file beginning (in that case it writes the original file beginning at the free space in the disk cluster, see "Beast" virus). On infection it uses very complex method of accessing to system undocumented functions. In some cases it corrupts the files on infection, these files are not recoverable and should be deleted.
This virus contains the internal text string:
