W32/Agobot-HC is an IRC backdoor Trojan and network worm.
W32/Agobot-HC is capable of spreading to computers on the local network protected by weak passwords.
When first run W32/Agobot-HC copies itself to the Windows system folder as csrss32.exe and creates the following registry entries to run itself on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\Microsoft Update Service = csrss32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\Microsoft Update Service = csrss32.exe
Each time W32/Agobot-HC is run it attempts to connect to a remote IRC server and join a specific channel.
W32/Agobot-HC then runs continuously in the background, allowing a remote intruder to access and control the computer via IRC channels.
W32/Agobot-HC attempts to terminate and disable various anti-virus and security-related programs.
