BackDoor.Deloder is a network worm which spreads to random IP addresses and installs a backdoor Trojan. BackDoor.Deloder tries to connect to remote Windows PCs using psexec.exe. The BackDoor.Deloder worm attempts to break into systems using easily guessed passwords and if it is able to login to Windows, it will connect through port 445 over TCP and will copy itself to the target computer. Deloder also drops an IRC Trojan into the Windows directory, which will allow a hacker to connect to your computer via several access methods. BackDoor.Deloder opens up a huge security hole on your machine and this places any financial or banking information stored on your computer in severe jeopardy and represents a serious security risk.
