Description of Taskhost.exe

Also known as Windows Task Host, it is located in %AppData%, which refers to the current users Application Data folder. By default, this is C:\Documents and Settings\\Application Data for Windows 2000/XP. For Windows Vista and Windows 7 it is C:\Users\\AppData\Roaming.

Its startup entry is started automatically from a Run, RunOnce, RunServices, or RunServicesOnce entry in the registry. When you open up Task Manager and see the process Taskhost.exe running, you may wonder what it is. Taskhost.exe is actually just a process that runs silently in the background. It is put there by Microsoft as a core part of Windows.

Windows uses taskhost.exe as the host for all DLL based services that are run. The process is very similar to svchost.exe in that it's a generic process used to load other entities. At startup TASKHOST checks the Services portion of the Registry to construct a list of DLL-based services that it needs to load, and then loads them. Because of this, taskhost.exe may open multiple instances of itself in order to handle DLL's that may be unrelated to one another, as there will be one instance of TASKHOST for every DLL-based service or grouping of services.

Taskhost.exe is able to record inputs and monitor applications. The true taskhost.exe file is a safe Microsoft Windows system process, called Host Process for Windows Tasks. However, writers of malware programs, such as viruses, worms, and Trojans deliberately give their processes the same file name to escape detection. Viruses with the same file name are for example Gen: Variant.Zusy.10792 (detected by BitDefender), and TROJ_GEN.R3EC2BG or TROJ_SPNR.11J311 (detected by TrendMicro).
