The kwsui.dll file is a Windows Dynamic Link Library (DLL) associated with Kingsoft Internet Security, a software suite developed by Kingsoft Corporation. As a DLL file, kwsui.dll contains program code, data, and resources utilized by Kingsoft’s security applications or potentially by web browser extensions. Typically, these files are used to execute common functions or to store important variables and constants used throughout a program. In the context of Kingsoft Internet Security, this DLL could be an essential part of the application, responsible for web protection features, hence the name ‘Webshield Module’.

Is it safe to run kwsui.dll?

On the surface, since kwsui.dll is part of a legitimate security suite, it would be deemed safe to operate. The file has been found in the subfolder of “C:\Program Files (x86)\kingsoft\kingsoft antivirus\”, and it usually has a file size of around 566,136 bytes in most cases.

Nonetheless, because DLLs can potentially be injected into all running processes and modify their behavior, it’s crucial to ensure that this file is indeed the genuine component from Kingsoft and not a cleverly disguised piece of malware.

Could it be a virus or malware?

The possibility of kwsui.dll being a virus or malware exists, particularly if the file is found outside its normal directory or has an abnormal file size. Although the file is digitally signed, indicating it has been verified by its creators, some malware may camouflage itself as kwsui.dll, especially if found in the Windows or Windows\System32 folders. Due to its ability to record keyboard and mouse inputs and monitor applications, users should be vigilant and verify the legitimacy of the file.
