W32/Sdbot-AAY is network worm with backdoor functionality for the
Windows platform.
W32/Sdbot-AAY runs continuously in the background, providing a backdoor
server which allows a remote intruder to gain access and control over
the computer via IRC channels.
W32/Sdbot-AAY spreads to network shares with weak passwords and via
network security exploits as a result of the backdoor element receiving
the appropriate command from a remote user.
The worm may drop a file RDRIV.SYS detected as Troj/Rootkit-W.
When first run W32/Sdbot-AAY copies itself to <Windows folder>\Edit.exe.
The worm registers itself as a service 'HexadecimaRepresentation' with
display name 'hexadecimal'.
The following patches for the operating system vulnerabilities exploited
by W32/Sdbot-AAY can be obtained from the Microsoft website:

W32/Mytob-HM is a mass-mailing worm and backdoor Trojan that can be
controlled through the Internet Relay Chat (IRC) network.
When first run W32/Mytob-HM copies itself to the Windows system folder
as yahooicons.exe and creates the following registry entries:
HKCU\System\CurrentControlSet\Control\Lsa
WINTASK
"yahooicons.exe"
HKCU\Software\Microsoft\OLE
WINTASK
"yahooicons.exe"

W32/Mytob-HM copies itself to the root folder as:
funny_pic.scr
my_photo2005.scr
see_this!!.scr
and drops a file called hellmsn.exe (detected by Sophos as W32/Mytob-D)
in the same location. This component attempts to spread the worm by
sending the aforementioned SCR files through Windows Messenger to all
online contacts.
W32/Mytob-HM also appends the following to the HOSTS file to deny access
to security related websites:
