TBHostSupport.dll

Have you stumbled across TBHostSupport.dll? Do you know anything about this file? Do you know which program it belongs to? Our malware researchers have discovered that the dynamic link library component belongs to the Conduit Search and Toolbar, and if you wish to delete these, you will need to remove the file as well. Unfortunately, this is not that easy, and many computer users report that they are struggling with the task. Besides supporting the activity you are most likely unhappy about, the disturbing DLL might be the cause of the irritating pop-up notifications. You may be able to stop these if you remove TBHostSupport.dll and get rid of the unreliable Conduit software successfully.

TBHostSupport.dll can be installed onto the computer in different locations and its size may wary; however, in most cases, computer users find it under %LOCALAPPDATA%\TBHostSupport\, and the file is as big as 458016 or 480032 bytes. Since the component has an autorun, it starts running as soon as the computer is booted up. If you have removed Conduit software already, you may be presented with pop-up alerts informing you that TBHostSupport.dll loading has failed as soon as the PC is booted up. Even though you could face a few different versions of the notification, here is one of the possible examples.

If you have not deleted Conduit software yet, it is unlikely that you have been faced by the suspicious pop-up notifications. Nonetheless, we certainly do recommend that you remove Conduit community toolbars and the potentially undesirable search tools which may have been installed. ConnectSo Toolbar, Quizulous Toolbar, Guffins Toolbar, and tens (if not hundreds) of other Conduit applications are considered to be unreliable and potentially undesirable because they have been developed to promote third party tools and programs. These toolbars always come bundled with the Conduit search tools, and these could be installed onto Google Chrome, Internet Explorer and Mozilla Firefox browsers without much of your notice.
