The following instructions have been created to help you to get rid of "BaiduBar" manually.
Use this guide at your own risk; software should usually be better suited to remove malware, since it is able to look deeper.
If this guide was helpful to you, please consider donating towards this site (http://www.safer-networking.org/index.php?page=donate).
Threat Details:
Categories:
adware
Description:
The application installs a toolbar (without user consent). This toolbar shows links to advertising sites. When uninstalled several registry entries and files remain on the system.
Removal Instructions:
Installed Software List:
You can try to uninstall products with the names listed below; for items identified by other properties or to avoid malware getting active again on uninstallation, use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) or RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) to locate and get rid of these entries.
Products that have a key or property named "sobar".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$WINDIR>\bdsl2.dll".
The file at "<$SYSDIR>\bdsl2.dll".
A file with an unknown location named "bdsl2.dll".
The file at "<$WINDIR>\bhosl2.dll".
The file at "<$SYSDIR>\bhosl2.dll".
A file with an unknown location named "bhosl2.dll".
The file at "<$PROFILE>\Local Settings\Application Data\Baidu\bar\Custom Buttons\custom.xml".
The file at "<$LOCALSETTINGS>\Temp\bdtmp\InstDll.dll".
The file at "<$PROGRAMFILES>\baidu\bar\baidubar.dat".
The file at "<$PROGRAMFILES>\baidu\bar\BaiduBar.dll".
The file at "<$PROGRAMFILES>\baidu\bar\img\logo.bmp".
The file at "<$PROGRAMFILES>\baidu\bar\BaiduBar.dll".
Make sure you set your file manager to display hidden and system files. If BaiduBar 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.
Folders:
Please use Windows Explorer or another file manager of your choice to locate and delete these folders.

The directory at "<$PROFILE>\Local Settings\Application Data\Baidu\bar".

Please read these instructions (http://forums.spybot.info/showthread.php?t=288) before requesting assistance,
Then start your own thread in the Malware Removal Forum (http://forums.spybot.info/forumdisplay.php?f=22) where a volunteer analyst will advise you as soon as available.
