Virus.DOS.DSME.Apex.2685 is a quite dangerous parasitic encrypted virus on DOS.


When the virus is run, it infects the first uninfected DOS executable file by writing itself to the end of the file.

Files infected by the virus may fail to run and hang the system when they are being executed.

Advanced details

This is a non memory resident virus.

MD5 hash:



When an infected program is run in September, the virus manifests itself in the form of sound and video effects, and it displays the message at the top of the screen:

My name is APEX v1.0_ Congratulations! PS:I wouldn't hurt your data.Be relax!.Ha

Obviously, the virus would hang the system after activation.

The message to be displayed would become garbage characters on some infected programs due to programming problems.

In the month of activation the virus does not infect any file.

Other details

The virus contains the encrypted internal text strings:

DSME v1.0
