This so-called dynamic link library (DLL) contains all the functions that have been transferred to a separate file. These transferred functions are available not only to this particular program, but can also be used by other applications. This sahook program does not have a visible window, and does not appear on the taskbar. The sahook file is not part of the Windows operating system. The file also can also affect other applications by changing their properties. Such manipulation can cause an application to do things other than what it is intended to do. The original file has been signed by a trusted signature authority. This lets you check your copy to see if it is a counterfeit. For this service - unlike Windows' own system services - there is no good description available. The file contains a digital signature from Verisign, a subsidiary of Symantec. Verisign thereby confirms this file's authenticity and integrity. Sahook.dll is capable of record keystrokes. sahook.dll appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts. However, this in itself is not sufficient reason to presume malicious intent, since even well-intentioned, professional software producers take advantage of compressed files. For this reason, 47% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.
If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant. It's a fact that many trojans try to cloak their true identity by calling themselves sahook.dll. With the above information or by using tools like Security Task Manager you can determine if, in your case, the file is an undesirable variant.
