Brief Description 

    

Nabload.DHW is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.

 

It uses stealth techniques to avoid being detected by the user:

  • It deletes the original file from which it was run once it is installed on the computer.

 

It uses several methods in order to avoid detection by antivirus companies:

  • It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.

 

Nabload.DHW does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
