The following instructions have been created to help you to get rid of "BrowserToolbar" 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:
Description:
Backdoor. Information about this one was collected from Symantec ( http://www.sarc.com/avcenter/venc/data/backdoor.autoupder.html ) and Trend Micro ( http://www.antivirus.com/vinfo/virusencyclo/default5.asp?VName=TROJ_SUA.A ) homepages, as I couldn't yet catch it.
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 pointing to "ausvc.exe".
Entries pointing to "bvt.exe".
Entries pointing to "mnsvc.exe".
Entries pointing to "absr.exe".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$WINDIR>\ausvc.exe".
The file at "<$WINDIR>\bvt.exe".
The file at "<$WINDIR>\mnsvc.exe".
The file at "<$WINDIR>\absr.exe".
Make sure you set your file manager to display hidden and system files. If BrowserToolbar 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!

You can use regedit.exe (included in Windows) to locate and delete these registry entries.
A key in HKEY_CLASSES_ROOT\ named "ABsr.ABsr", plus associated values.
A key in HKEY_CLASSES_ROOT\ named "ABsr.ADrv", plus associated values.
