Stranger.734
It is a dangerous memory resident parasitic encrypted virus. It traces and hooks INT 21h, then it writes itself to the middle of COM files that have the block of constant data inside. The virus stores this constant byte and overwrites this block by the virus code, as a result the file length does not grow. While executing the virus restores this block and passes the control to the host program. On the file opening the virus checks its name and sometimes overwrites *.DB* files. The virus also contains the text:
*Stranger*
