Rlls.dll is a file related to the adware-type program which appears on the system out of nowhere and causes users' frustration. This is not a Windows file, so it can be removed, especially when causing problems. This is a process related to Relevant Knowledge – an infamous adware.[1] The file is detected by various antivirus programs and can be called malicious. Sophos identifies it as Generic Proxy-OSS Application, and BitDefender identifies it as Gen:Adware.Heur.Hy9@R0CzHwji or Gen:Adware.Heur.wy8@R86RlZoi. All these results depend on the particular database and terms used by anti-malware software. However, no matter what name the program is using, it is a warning that you need to remove Rlls.dll from the system.

The main issue caused by Rlls.dll virus is high CPU's usage and problems hailing from that. The high usage of CPU has been the main sign that the process is dangerous.[2] In this case, that's because of the .dll's relation with PUP called RelevantKnowledge. 

Rlls.dll is a dynamic link library. Typically, DLLs are responsible for processes and functions that other programs can call. This particular file can be injected in any other process and can alter or manipulate those programs.

Furthermore, Rlls.dll has a digital signature and can connect to the internet, record keyboard inputs and monitor program processes. This fact and the relation with adware means that you need to employ professional tools to fully get rid of the infections.

This file has no program window and no description so Rlls.dll changes and manipulates other applications. This way, people think those apps are malicious and have no idea that this DLL is the main cyber threat. Security experts[3] note that this file and related programs can be detected in various other names, not only those that we mentioned above.

Since Rlls.dll removal requires reputable tools we can recommend using Reimage. You need a full system scan to indicate all programs, files, and applications that this file affected or is associated with.

Avoid getting adware and malicious files

Since this file is associated with the adware-type program the main distribution technique may be software bundles when PUPs are packed with freeware and distributed on the internet via insecure installations or deceptive ads and questionable download websites.

However, this file may come from spam email attachments with other malicious files. It is possible the this DLL is set to infect the device with more prominent malware like ransomware or perform more malicious processes in the background. The minute you open an infected file on the system file loads on the device and you cannot notice it until it starts to cause additional issues with the PC.

You can avoid these cyber infections by opting for Advanced or Custom installations, paying more attention during those processes and choosing reputable sources for software. Also, you should choose wisely which emails to open right away because infected documents may be planted on safe-looking emails disguised behind the name of a legitimate service. Try scanning the file before opening on the device.
