W32/Poebot-E is a worm which attempts to spread to remote network shares with weak passwords. It also contains backdoor Trojan functionality allowing unauthorised remote access to the infected computer via IRC channels.
W32/Poebot-E moves itself to radeonfx.exe in the %WINDOWS%\system32 folder and creates the following registry entry to ensure it is run at system logon:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Windows DLL Loader
%WINDOWS%\system32\radeonfx.exe
W32/Poebot-E can also download and execute remote files on the infected computer, flood other computers with network packets, retrieve system information and execute arbitrary commands.
