W32/Agobot-AGD

Please follow the instructions for removing worms.

Change any data that may have become compromised.

Replace the Hosts file from a backup or edit it in Notepad to remove the changes that the worm has made.

You will also need to edit the following registry entries, if they are present. Please read the warning about editing the registry.

At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.

Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.

Locate the HKEY_LOCAL_MACHINE entries:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
Zekio Startups
condll.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\
Zekio Startups
condll.exe

and delete them if they exist.

Close the registry editor.

W32/Agobot-AGD is an IRC backdoor Trojan and network worm.

W32/Agobot-AGD is capable of spreading to computers on the local network protected by weak passwords.

When first run, W32/Agobot-AGD copies itself to the Windows system folder as condll.exe and creates the following registry entries to run itself each time a user logs on:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
Zekio Startups
condll.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\
Zekio Startups
condll.exe

The backdoor component runs continuously in the background providing backdoor access to the computer through IRC channels. The backdoor component can be instructed to perform the following functions:

harvest email addresses
steal product registration information for certain software
take part in Distributed Denial of Service (DDoS) attacks
scan networks for vulnerabilities
download/execute arbitrary files
start a proxy server (SOCKS4/SOCKS5)
start/stop system services
monitor network communications (packet sniffing)
add/remove network shares
send email
log keypresses

W32/Agobot-AGD attempts to terminate and disable various anti-virus and security related programs and modifies the HOSTS file located at <SYSTEM>\Drivers\etc\HOSTS, mapping selected anti-virus websites to the loopback address 127.0.0.1 in an attempt to prevent access to these sites. The following urls will be appended to the HOSTS file:

'avp.com'

'customer.symantec.com'
