Trojan.DOS.On4Ever or On4Ever is a trojan that runs on MS-DOS.


The length of the trojan is 111 bytes. Being executed it creates the file 00000001.COM, writes itself to there, writes to the keyboard buffer the string 00000001.COM to force DOS executing that file, and exits. Then the file 00000001.COM creates and executes the file 00000002.COM, then 00000002.COM creates and executes 00000003.COM and so on.
