The following instructions have been created to help you to get rid of "Win32.Agent.bid" manually.
Use this guide at your own risk; software should usually be better suited to remove malware, since it is able to look deeper.

Threat Details:
Categories:
trojan
Description:
Win32.Agent.bid copies an executable file into Windows directory, starts itself via autorun as "Firewall auto setup" without giving the user a possibility to cancel that process. Also blocks some buttons in applications (e.g. 3 main buttons in SpyBot).
Removal Instructions:
Autorun:
Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd), RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) or msconfig.exe to remove the following autorun entries.
Entries named "Firewall auto setup" and pointing to "*\Temp\winlogon.exe".
Entries named "startdrv" and pointing to "<$WINDIR>\Temp\startdrv.exe".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$LOCALSETTINGS>\Temp\winlogon.exe".
The file at "<$SYSDIR>\DefLib.sys".
The file at "<$LOCALSETTINGS>\temp\winlogon.exe".
The file at "<$LOCALSETTINGS>\temp\winlogon.exe".
The file at "<$SYSDIR>\comi.dll".
The file at "<$SYSDIR>\confg.xml".
The file at "<$SYSDIR>\help.txt".
The file at "<$SYSDIR>\keys.xml".
The file at "<$SYSDIR>\5_exception.nls".
The file at "<$SYSDIR>\ctfmon.rgn".
The file at "<$WINDIR>\Temp\startdrv.exe".
Make sure you set your file manager to display hidden and system files. If Win32.Agent.bid uses rootkit technologies, use our RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!
Important: There are more files that cannot be safely described in simple words. Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) to remove them.
