This page aims to help you remove Murder Setup “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Murder Setup is an adware application which has recently been reported to our “How to remove” team by a number of users. This application has not been categorized as malware or as a virus, but most of the people who have it on their systems are nevertheless seeking effective methods to have it uninstalled. The reason is, this potentially unwanted application tends to be very annoying and to interrupt their regular web browsing with hard-to-remove ads, unwanted pop-ups, nagging banners and automatic page-redirects to unfamiliar sponsored sites. According to its developers, Murder Setup is a free application which is created to enhance the users’ web experience and to improve their time online by offering them good deals, web offers and targeted ads. However, in reality, the application is aimed at showing pay-per-click ads on the “infected” PC and at boosting the traffic of its partner websites via automatic page-redirects. A number of users report that the adware typically redirects their web searches to sketchy sites and shady offers, which often promote products and services with questionable quality. Some even share their fear of bumping into malicious web pages, where their system may get infected by more dangerous threats and viruses such as Trojans and Ransomware. If you are also concerned about the behavior of Murder Setup and the ads and sites that it makes you interact with, we suggest you take a look at the instructions in the removal guide below and follow them in order to safely uninstall the undesired software and remove all of its nagging commercials from Chrome, Firefox, Explorer and other browsers that might have been affected.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

Questionable activities performed by Murder Setup

As a typical adware, Murder Setup cannot perform malicious activities and harm the users’ computers in any serious way. Still, despite lacking the harmful code of a real virus, this application could perform some questionable activities. For instance, the adware may keep track of your latest web searches. This is a common ability of most ad-generating applications since they are mainly designed to earn online revenue from paid ads. And in order to do this more effectively, they tend to track your online activities, browsing history, use cookies and inject numerous annoying ads on the pages that are loaded in your web browser. Additionally, as a result of their aggressive advertising activity, such applications may slow down your browser and make it unresponsive to your searches. Not to mention that, indeed, there may be a certain risk of clicking on something misleading or landing on pages that may be compromised by real viruses such as Spyware, Ransomware or similar threats. That’s why it is usually advisable to uninstall the annoying adware from your PC and remove its ads in order to permanently save yourself from its invasion.

It is also very important to learn how to prevent applications like Murder Setup from entering your PC in the future because they may take over your browser again if you are not careful. For that reason, you should be selective with regards to the software that you install on your PC because adware and other similar applications could oftentimes be found as “additional” or “bonus” components added to some other free programs. They can also be bundled with different free add-ons, plug-ins, games, and tools and are usually hidden under the Advanced or under the Custom installation settings.
