A serious impact virus/Trojan is circulating on the net that infects systems without user clicking, going to links, or any user interface if you’re connected to the internet.

<O:pIF YOUR IE OR OTHER INTERNET BROWSER HAS SLOWED DOWN, AND E-MAIL ACCESS [SEND AND RECEIVE] HAS SLOWED DOWN TO A SNAILS PACE, OR YOUR SERVERS ARE BEING RESET, YOU SHOULD SCAN FOR THIS VIRUS/TROJAN.

(Description):
Psyme is a notoriously cunning downloader. The distributors of Psyme are known to actually insert links to the Trojan in other, legitimate websites and to propagate popups that also link to the Trojan. Clicking on the link or popup will initiate an automatic download of the Psyme Trojan that will then make contact with the Internet connection of the infected computer. From that point, it downloads other Malware, usually in the form of spying utilities like keyloggers.

Psyme abuses a vulnerability in older versions of Internet Explorer. By exploiting the way Explorer receives ADODB stream objects, the Trojan can download and install without being checked. ADOdb is a database abstraction written for certain programming languages; it allows Explorer to interpret information from various types of databases, regardless of which language they are written in.

Psyme has two popular variants; one is written in Visual Basic Script (VBS) and one in Java (JS). They have the same objectives. Additionally, there are another Trojan Downloaders called Psymedo and Trunlow that have characteristics so similar to Psyme that some authorities list them as the same program.

What is a Downloader?As its name implies a Downloader is the part of a malicious program that actually downloads and installs software onto your computer. Downloaders can be found on any type of malware, but they're most commonly associated with Trojans because these programs' objective is to download material without the user being aware of it. <O:p

The Downloader is usually responsible for executing the programs it has loaded. It may do this as soon as the downloading process is complete, or it may register the execute command with the local system requirements. This way the the malicious software will autorun at a specified time or after a specified action. The names of the downloaded files and the locations may be either encoded in the Downloader itself or sent via an unseen website.

Note: This Psyme manual removal process is difficult and you run the risk of destroying your computer. We highly recommend you use the online scans and removal tools.

McAfee is not aware or lists this Trojan, and does not detect this virus/Trojan<O:pThis Trojan self loads onto your system without any clicks, links, or user actions, from infected web sites.

I'm not sure where you got this information because you don't quote a source. However, the Symantec website says that this Trojan was first discovered in 2004. I checked a couple of other security websites, including the US-CERT website ( http://www.us-cert.gov/ ), and they show no recent activity with this trojan. For those who aren't schooled in computer security, US-CERT is the United States Computer Emergency Readiness Team, which is a group of researchers and professionals who constantly monitor threats to the US computer infrastructure and report them to the public. I have found that they are pretty good at posting notifications when a new threat has been found. By monitoring Symantec, US-CERT, and a few other sites, I feel that I've been sufficiently warned of emerging threats over the past 3-4 years that I've been doing security at my company.

I suspect that this is just another chain mail. These ultra-urgent warning e-mails pop up from time to time. They typically report that a brand new virus/worm/malware is circulating and Microsoft/Symantec/Norton/[plug in any big name] can't stop it and we're all in danger of being infected. Some of them try to convince the recipient to delete a system file by saying that it is really a virus file. Some people are so frightened by the e-mail that they delete the file and have to call in a professional to fix what they did.

A couple of months ago, our CEO forwarded me an e-mail that he had received about a "Brand new virus" that could infect any Microsoft Operating System without warning and without the user doing anything. The e-mail said that Microsoft was scrambling to find a fix but had no idea how to block it and was trying to cover it all up until they figured out how to fix it. With a few quick searches, I found that the e-mail was actually a chain e-mail whose purpose was to frighten people and waste their time. They had used the name of a virus that was first reported in 2001 and was actually a low threat level virus.

Symantec's website says that their virus protection updated since April 2004 will detect and clean this Trojan. They also call this a low threat level with easy containment and removal. The following is an excerpt from the Symantec website about the Psyme Trojan:

TECHNICAL DETAILS

When Downloader.Psyme runs, it performs the following actions:

1. Sends a Get request to a predetermined Web site, and tries to download a file.

2. Creates an ADODB Stream object and executes the file.

3. May attempt to save the file on the computer.

4. May also try to send a confirmation to the download server that the file has been retrieved.


The behavior of this downloader varies. What it may add to the registry or StartUp folders also varies.

In some versions, the following files are saved:

* C:\Windows\m.exe
* C:\Windows\mp.exe
* C:\Windows\dp.exe
* C:\Winnt\m.exe
* C:\Winnt\mp.exe
* C:\Winnt\dp.exe
* C:\Windows\uninstl.exe

************************************************** *************

I would suggest to everyone that they use a firewall and keep their virus protection up-to-date. Have it check for updates automatically every day or every time you connect to the Internet. If you do that, you will be as protected as you possibly can be short of not connecting to the Internet.

Stay nude.
