W32/Agobot-QF

Please follow the instructions for removing W32/Agobot-QF.

W32/Agobot-QF is an IRC backdoor Trojan and network worm which establishes
an IRC channel to a remote server in order to grant an intruder access to the compromised machine.

This worm will move itself into the Windows System32 folder under the filename EXPLORED.EXE and may create the following registry entries so that it can execute automatically on system restart:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Windows Login = explored.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Windows Login = explored.exe

This worm will also attempt to glean email addresses from the Windows Address Book and send itself to these email addresses using its own SMTP engine with itself included as an executable attachment.

W32/Agobot-QF will attempt to terminate anti-virus and software firewall processes, in addition to other viruses, worms or Trojans.

This worm will search for shared folders on the internet with weak passwords and copy itself into them. A text file named HOSTS may also be dropped into
C:\<Windows System32>\drivers\etc which may contain a list of anti-virus
and other security related websites each bound to the IP loopback address of 127.0.0.1 which would effectively prevent access to these sites.

For example:

W32/Agobot-QF can sniff HTTP, ICMP, FTP, VULN and IRC network traffic and steal data from them.

The following vulnerabilities can also be exploited to aid propagation on unpatched systems and manipulate registry keys:

Remote Procedure Call (RPC) vulnerability

Distributed Component Object Model (DCOM) vulnerability

RPC Locator vulnerability

IIS5/WEBDAV Buffer Overflow vulnerability

For more information about these Windows vulnerabilities, please refer to the following Microsoft Web pages:

Microsoft Security Bulletin MS03-001
Microsoft Security Bulletin MS03-007
Microsoft Security Bulletin MS03-026
(Microsoft Security Bulletin MS03-026 has been superseded by Microsoft Security Bulletin MS03-039).

W32/Agobot-QF can also polymorph on installation in order to evade detection and share/delete the admin$, ipc$ etc drives.

It can also test the available bandwidth by attempting to GET or POST data to the following websites:

'yahoo.co.jp'
'www.nifty.com'
'www.d1asia.com'
'www.st.lib.keio.ac.jp'
'www.lib.nthu.edu.tw'

'www.switch.ch'
'www.1und1.de'
'verio.fr'
'www.utwente.nl'
'www.schlund.net'

W32/Agobot-QF can also be used to initiate denial-of-service (DoS) and
distributed denial-of-service (DDoS) synflood/httpflood/fraggle/smurf etc attacks against remote systems.

This worm can steal the Windows Product ID and keys from several computer applications or games including:
