TBHostSupport.dll Removal Guide

It has been discovered that the file TBHostSupport.dll is related to Conduit browser add-ons. It is believed that this dynamic library file is connected to an error message that appears when Windows loads. This message, of course, will pop-up only if you have leftover files from some Conduit program on your computer. You should get rid of these files in order to eliminate the error message. You can locate the files with a malware scanner and then remove them by yourself. Another option is to acquire a reliable antimalware program that will remove all unwanted files and programs from your computer. We recommend doing this right away.

DLL files are not dangerous in any way. They are used by all sorts of programs. These files contain all kinds of codes and data. They can even help save some disc space as they are reusable. As we have mentioned above, TBHostSupport.dll is related to the Conduit browser extensions. This group of programs has numerous members. Some examples are KeyBar Toolbar, Social Search Toolbar, and Freecorder Toolbar. All of these use Conduit Search as their search engine and they can even set it as your default search provider.

Research has found that TBHostSupport.dll is also associated with CltMngSvx.exe. This file is known to have nine different versions and to be related to a Conduit program called Search Protect. Conduit browser extensions can end up on your computer in all sorts of ways. They usually have official websites from which they can be downloaded. However, most often they get installed along with other programs. Bundled downloads are a common way for suspicious programs to spread. If you do not notice the Conduit program, it will be installed unbeknownst to you. What is more, they can then modify some of the browser’s settings. This is why they are often referred to as browser hijackers.

The error message that we mentioned may say one of two things:

RunDLL – There was a problem starting c:\users\%USERNAME%\appdata\local\tbhostsupport\TBHostSupport.dll. The specified module could not be found.

RUNDLL – Error loading c:\users\%USERNAME%\appdata\local\tbhostsupport\TBHostSupport.dll. The specified module could not be found.

Conduit programs usually configure your PC so that they can autostart upon Windows loading. This means that some files which belong to the Conduit program you have removed are still on your PC and they are trying to launch TBHostsupport.dll.

Fixing the issue can be performed manually. You will have to remove the registry key that tries to run TBHostsupport.dll. However, this will mean that you will have to tamper with the system’s registry. We do not recommend layman users to attempt this as they may end up harming their system themselves. The best way to fix the problem is by using a reliable malware removal program. Such a tool will not only defend your PC against infections, but it can also remove potentially unwanted programs and all files related to them.
