The following instructions have been created to help you to get rid of "ConHook" 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:
ConHook ( BHO ) copies itself to the system folder (dll) and connects to the internet without giving the user a possibility to cancel that process. Can also download and execute unwanted software.
Removal Instructions:
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
A file with an unknown location named "dpwdno.dll".
The file at "<$SYSDIR>\erslog.dll".
A file with an unknown location named "erslog.dll".
A file with an unknown location named "calacm.dll".
Make sure you set your file manager to display hidden and system files. If ConHook 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.
