McAfee DAT files contain detection and repair information for threats. The Minimum DAT field specifies the lowest/oldest DAT version that is capable of detecting the first incarnation of a threat, and the release date. The highest/newest DAT version should always be used for the most complete protection and are available on the Anti-Virus Updates page.
Each description displays the minimum, fully tested, DAT version that includes regular detection for a particular threat. These fully tested DATs are released on a daily basis. If necessary, they are also released when a Medium, Medium On Watch, or High risk threat is discovered. An EXTRA.DAT will also be posted for these more prevalent threats, if necessary.
For each description listed, detection is always available. In the event that the DAT version specified is not yet available, an EXTRA.DAT file may be downloaded via the McAfee AVERT Extra.dat Request Page. Alternatively, minimally tested HOURLY BETA DAT files are available for downloading.
Overview
This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.
Characteristics
This detection is for a mass-mailing worm that combines W32/Mydoom@MM functionality with W32/Sdbot.worm functionality.
Mail Propagation
The virus arrives in an email message as follows:
From:
(Spoofed email sender)
Do not assume that the apparent sender address is an indication that the sender is infected. Additionally you may receive alert messages from a mail server saying that you are infected, which may not be the case.
Subject:
(Varies, such as)
- Notice: **Last Warning**
- *DETECTED* Online User Violation
- Your Email Account is Suspended For Security Reasons
- Account Alert
- Important Notification
- *WARNING* Your Email Account Will Be Closed
- Security measures
- Email Account Suspension
- Notice of account limitation
Body:

- Once you have completed the form in the attached file , your account records will not be interrupted and will continue as normal.
- The original message has been included as an attachment.
- We regret to inform you that your account has been suspended due to the violation of our site policy, more info is attached.
- We attached some important information regarding your account.
- Please read the attached document and follow it's instructions.
Attachment:
(Varies - chooses from the following list of prefaces)
- email-info
- email-doc
- information
- account-details
- document
- INFO
- instructions
- info-text
- information
The attachment name may have one or two file extensions, in which case multiple spaces may be inserted as well, for example:
- document.htm (many spaces) .pif
Extensions:
(Varies, chooses from the following list)
First extension:
Final extension:
These are examples of common names, but they can also be random. The file may also arrive in a ZIP archive.
Installation
When the attachment is run, the virus copies itself to the Windows System directory (e.g. C:\Windows\System32\ on Windows XP) as Lien.exe
.
The Hosts file (typically found in C:\Windows\System32\Drivers\etc\) is also appended to direct several security websites to the local host, so they cannot be accessed. This file is detected and cleaned as Qhosts.apd.
Registry keys are created to load the worm at startup:
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
RunServices "http://www.lienvandekelder.be" = Lien.exe
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Run "http://www.lienvandekelder.be" = Lien.exe
Additional the following value is set:
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess "Start" = 4
