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

Are you wondering why your browser has been redirecting you to different web pages recently? And where has this new search engine or a toolbar come from? We might have the answer to those and any other similar questions about any recent browsing disturbances that you might be currently dealing with. In this article, we are going to discuss where all these browser changes come from, what is causing them and how you can remove them. Most probably your Chrome, Firefox or Internet Explorer browser (or any other browsing software that you might be using) is affected by the presence of a browser hijacker which has changed the way your default browsing app looks and operates.

Browser hijackers are pieces of software which are commonly used as advertising tools and you can install them on your system in many ways without necessarily knowing that. Such pieces of software are developed by marketers and advertisers with the idea to generate ads, pop-ups, banners and sponsored web pages on the peoples’ screen through their browser. In order to do that, the hijackers usually install new components that modify your default search engine, homepage, new tab page or toolbars and force you to use them instead of your default settings. The security specialists have recently discovered a browser-redirecting application called Scorecardresearch Virus which typically does that to the computers it gets installed on and could be one of the most probable reasons for the redirects and browsing disturbance that you might be experiencing. If you have it on your PC, we suggest you carefully read the information that our team has prepared below. Fortunately, there is probably nothing to be worried about because such software is generally not harmful. Still, it can be very annoying and in the next paragraphs, we will tell you in detail how you can effectively remove it. What is more, for the effective uninstallation we have prepared a detailed Removal Guide with step-by-step instructions.

Should browser hijackers such as Scorecardresearch Virus be considered as a computer threat?

A lot of users when faced with strange browser changes (such as replacements in their search engine or homepage, installation of a new toolbar, sudden web page redirects and generation of many intrusive ads) first think that the system has probably been infected with some sort of a virus. This is a common confusion among most people, but the truth is such symptoms are not necessarily signs of a malware invasion. In fact, they are signs of the presence of a browser hijacking software on the system.

Now, generally speaking, browser hijackers are not as harmful as Trojan horses or as Ransomware viruses and they significantly differ from those kinds of malware. The purpose of most malicious infections like the ones mentioned above is to cause harm to the targeted machine or to mess with the files that are on it while the purpose of the majority of applications like Scorecardresearch Virus is primarily marketing-oriented. So, as you can see, the difference between most forms of malware and browser hijackers is quite significant. Scorecardresearch Virus, for instance, can usually only affect your browser and maybe some of your general internet settings without actually corrupting or deleting anything on your computer. A Trojan, on the other hand, can destroy your system and all the data found on it.

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:

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.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

  1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
  2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
  3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.

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.

Type Regedit in the windows search field and press Enter.

Inside, press CTRL and F together and type the threat’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!

The hijacker will likely never try to steal sensitive information from you or mess with your files. A Ransomware, however, will not only encrypt your most valuable data, but it will also require you to pay a ransom if you want the locked-up files recovered. Pretty much none of the representatives of the browser hijackers’ family known to our team have ever been related to such criminal activities, so if you are worried about your PC know that there’s no reason to panic. At its worst, such software can only irritate you by constantly disturbing your normal web activity and imposing you its browsing changes. Fortunately, the disturbance can be removed fairly easy. Even a non-experienced user can uninstall a program like Scorecardresearch Virus, but when it comes to real viruses, professional assistance may oftentimes be needed.

Prevention and protection tips against browser hijackers:

Despite that Scorecardresearch Virus and other similar apps are normally not regarded as actual malware threats, having them on your computer is certainly not a pleasant experience. That’s why you should learn how to avoid such software and protect your PC from it. To begin with, we will advise you to carefully select the sources of new software that you tend to use and also to always customize the setup of any new program that you want to install on your PC. This is because programmers often distribute browser hijackers and similar ad-generating programs by bundling them inside the installers of other programs, different ads, games, optimization tools, converters, etc. Downloading such bundle, however, won’t automatically contaminate you with the hijacker. You will have to actually run the setup and (as most of the users usually do) perform the installation through the Automatic/Standard options. However, if you want to make sure that only the main program of the bundle gets installed with any added applications being left out of the installation, you should opt for Custom/Advanced/Manual installation options instead. Using them will allow you to remove any potentially unwanted programs from the software package before they become part of your system.
