The rlls.dll file stands out in the digital landscape but not for commendable reasons—it’s a part of software that’s often classified under the umbrella of potentially unwanted programs (PUPs), specifically belonging to RelevantKnowledge. The program runs in the background and lacks a visible window, operating quietly on the system, often without the user’s explicit consent.

The rlls.dll file is associated with the RelevantKnowledge, which falls within the scope of market research. It’s supposedly used to gather anonymous user data to improve products and services. However, its surreptitious nature has raised concerns, leading to its detection as malware or a PUP by various antivirus products.

RelevantKnowledge is created by TMRG, Inc., and it is typically found within the C:\Windows\System32 or C:\Program Files\RelevantKnowledge directories on your computer. As a dynamic link library (DLL) file, it contains code and resources that can be utilized by multiple programs, which is standard for DLL files.

Many users and automated systems suspect rlls.dll of malicious activity because it has the capability to monitor applications, manipulate other programs, record keyboard and mouse inputs, and connect to the Internet. This kind of behavior can be indicative of spyware or adware, raising flags about user privacy and system integrity.
