From; Sophos Alert System:
Name: W32/Agobot-XX
Type: Win32 worm
Date: 28 May 2004
A virus identity (IDE) file which provides protection is
available now from the Sophos website, and will be incorporated
into the July 2004 (3.83) release of Sophos Anti-Virus.
Customers using Enterprise Manager, PureMessage and any of the
Sophos small business solutions will be automatically protected
at their next scheduled update.
At the time of writing, Sophos has received just one report of
this worm from the wild.
Information about W32/Agobot-XX can be found at:

Description
W32/Agobot-XX is capable of spreading to computers on the local network
protected by weak passwords.
When first run W32/Agobot-XX copies itself to the Windows system folder as
dmrss.exe and creates the following registry entries to run itself on
startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
DSService = dmrss.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
DSService = dmrss.exe
Each time W32/Agobot-XX is run it attempts to connect to a remote IRC server
and join a specific channel.
W32/Agobot-XX then runs continuously in the background, allowing a remote
intruder to access and control the computer via IRC channels.
W32/Agobot-XX attempts to terminate and disable various anti-virus and
security-related programs.
This worm will search for shared folders on the internet with weak passwords
and copy itself into them. A text file named HOSTS may also be dropped into
C:\<Windows System32>\drivers\etc which may contain a list of anti-virus
and other security-related websites each bound to the IP loopback address of
127.0.0.1 which would effectively prevent access to these sites.
