W32/Agobot-PR is an IRC backdoor Trojan and network worm.

W32/Agobot-PR spreads using a variety of techniques including exploiting weak 
passwords on computers and SQL servers, exploiting operating system 
vulnerabilities (including DCOM-RPC, LSASS, WebDAV and UPNP) and using 
backdoors opened by other worms or Trojans.

When first run W32/Agobot-PR copies itself to the Windows system folder as 
SRV325.EXE and creates the following registry entries to run itself on startup:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Srv325
Srv325.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Srv325
Srv325.exe

Each time W32/Agobot-PR is run it attempts to connect to a remote IRC server 
and join a specific channel.

W32/Agobot-PR then runs continuously in the background, allowing a remote 
intruder to access and control the computer via IRC channels.

The Trojan attempts to terminate and disable various anti-virus and 
security-related programs and modifies the HOSTS file located at 
%WINDOWS%\System32\Drivers\etc\HOSTS, mapping selected anti-virus websites to 
the loopback address 127.0.0.1 in an attempt to prevent access to these sites. 
Typically the following mappings will be appended to the HOSTS file:

127.0.0.1 www.symantec.com
127.0.0.1 securityresponse.symantec.com
127.0.0.1 symantec.com
127.0.0.1 www.sophos.com
