What Is Trojan Vundo

This section provides a quick description of trojan and adware Vundo (also known as VirtuMonde and VirtuMundo).

Vundo is a malicious program for Windows system. Here are some short descriptions of Vundo I found on the Internet:

1. From www.spynomore.com/articles/vundo-trojan-specifics-and-removal.php:

Vundo (also known as VirtuMonde and VirtuMundo) is a malicious
software application that combines both adware and trojan 

Vundo is wide spread today and is probably one of the hardest programs
to get rid of. Once installed, Vundo downloads and displays pop-up
advertisements that often promote questionable computer-enhancement 
programs or fake anti-virus or anti-spyware utilities. Lately, Vundo
has been advertising several rogue programs called WinFixer2005, 
WinAntiVirus Pro 2006, WinAntiSpyware and RazeSpyware.

2. From vil.nai.com/vil/content/v_127690.htm:

This is a trojan detection. Unlike viruses, trojans do not 
self-replicate. They are spread manually, often under the premise that
they are beneficial or wanted. The most common installation methods 
involve system or security exploitation, and unsuspecting users 
manually executing unknown programs. Distribution channels include 
email, malicious or hacked web pages, Internet Relay Chat (IRC), 
peer-to-peer networks, etc.

3. From en.wikipedia.org/wiki/Vundo:

The Vundo trojan is a trojan horse that may cause popups advertising
rogue antispyware programs. It infects victims' computers by 
exploiting a vulnerability in Sun Java 1.4 and earlier versions. 
Many of the popups advertise a program called Sysprotect.

But I don't think any of the above descriptions is accurate. Not long ago, I was asked by a friend of mine to look at his Vundo infected computer. I want to share some notes with you that may help you understand Trojan Vundo better.
