Troj/Delf-ALI is a worm and IRC backdoor Trojan for the Windows platform.

Troj/Delf-ALI spreads to other network computers by exploiting common buffer overflow vulnerabilities, including RPC-DCOM (MS04-012).

Troj/Delf-ALI runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.

Troj/Delf-ALI includes functionality to access the internet and communicate with a remote server via HTTP.

When Troj/Delf-ALI is installed it creates the clean text file <System>\msguid32.dll.
