and posts a message: IMStart. which is an invitation to connect to the victims computer.when connected, the attacker can send the worm to more people and control the victims pc. However, there is a flaw: as [[MSN Messenger]] does not allow you to send whole files, instead of spreading, The victim will get a lot of dialogue boxes saying: "you cannot send a folder, please send one file at a time." Thefore you must have [[Windows Live Messenger]] to spread it. |

==Removal== |
|||
Go to the start menu, then run, and type [[Windows Registry|regedit.exe]] and when the system registry opens up, go to:[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ShellServiceObjectDelayLoad], and delete either rdihost, rdshost or rdfhost and restart your computer. Then search in %windows% for photo album.zip, and delete it. Then, search in %system% for rdshost.dll, if you have it, delete it. Search in %system% again for rdfhost.dll and rdihost.dll. Once you have done that, restart your computer. The worm should now be gone. |

Backdoor.Win32.IRCBot (also known as W32/Checkout (McAfee), W32.Mubla (Symantec), W32/IRCBot-WB (Sophos), and Backdoor.Win32.IRCBot.aaq (Bydoon Center)[1]) is a backdoor computer worm that is spread through MSN Messenger and Windows Live Messenger. Once installed on a PC, the worm copies itself into a Windows system folder, creates a new file displayed as "Windows Genuine Advantage Validation Notification" and becomes part of the computer's automatic startup.[2] In addition, it attempts to send itself to all MSN contacts by offering an attachment named 'photos.zip'. Executing this file will install the worm onto the local PC. The Win32.IRCBot worm provides a backdoor server and allows a remote intruder to gain access and control over the computer via an Internet Relay Chat channel.[1] This allows for confidential information to be transmitted to a hacker.
Because of a lack of standard naming conventions and also because of common features, variants of Win32.IRCBot can often be confused with the Agobot and Spybot family of worms. For example, Sophos lists Backdoor.Win32.IRCBot.ul, W32/Poebot-JT worm, and Win32/IRCBot.TS as aliases of the W32/Gaobot.worm.gen.e worm, a member of the Agobot family.[3]
