ThisDescription
W32/Agobot-FZ is an IRC backdoor Trojan and network worm.
W32/Agobot-FZ is capable of spreading to computers on the local network
protected by weak passwords.
When first run W32/Agobot-FZ copies itself to the Windows system folder as
msdtc32.exe and creates the following registry entries to run itself on
startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
Video Device Loader = msdtc32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\
Video Device Loader = msdtcc32.exe
Each time W32/Agobot-FZ is run it attempts to connect to a remote IRC server
and join a specific channel.
W32/Agobot-FZ then runs continuously in the background, allowing a remote
intruder to access and control the computer via IRC channels.
W32/Agobot-FZ attempts to terminate and disable various anti-virus and
security-related programs.
Recovery
Please follow the instructions for removing worms.
Check your administrator passwords and review network security.
You will also need to edit the following registry entries, if they are
