Paper Extension

Paper Extension is one of the latest examples of a browser hijacking app. Paper Extension may typically take over your default web browser and force it to display various sponsored ads and redirect prompts during your web surfing sessions.


Every active online user knows that they should protect their computers from online hazards such as viruses, Trojans, spyware, ransomware and other sketchy or malicious programs. However, not everyone distinguishes malware and potentially unwanted software. The latter is not identical to computer viruses and is not intended to destroy the computer it is installed on.

Browser hijackers such as Paper Extension are a clear example of such software which normally do not damage your device but which are generally unwelcome. For the most part, such programs start flooding the system’s default web browser with nagging advertising materials such as intrusive pop-ups, auto-redirects to sale sites, obstructing banners, and on-screen notifications during each browsing session. Popular browsing apps such as Chrome, Edge, Firefox and Opera become a common target of browser hijacking.

The Paper Extension Virus

Browser hijackers such as the Paper Extension virus are a clear example of such software which normally do not damage your device but which are generally unwelcome.The Paper Extension virus will start flooding the system’s default web browser with nagging advertising materials such as intrusive pop-ups, auto-redirects to sale sites, obstructing banners, and on-screen notifications during each browsing session.

The typical symptoms that usually indicate that an app like Paper Extension, Agafurretor or Plant extension has attached itself to your main web browser include changes in the homepage address, the new tab page, the browser’s main search engine and some other key browser elements that are responsible for your online experience. These elements are often changed by the hijacker without the user’s permission. And while none of them will explicitly impact your browser’s privacy or your computer’s safety, it is still advisable to uninstall the changes and remove the program that is causing them as soon as you can. In most cases, this is the best way to stop the abuse of the aggressive advertisements on your screen and restore your previous web browsing settings.

Unfortunately, uninstalling a browser hijacker is not an easy process. Despite not being malware or a virus, this type of software may often install some helper components deep inside your system in order to facilitate its ad-generating and page-redirecting activities. That’s why, unless you detect and remove all of these components, it may be impossible to permanently remove the invasive software.

The good news is that there is a way to do that without contacting a security professional and, in the removal guide below, we will show you all the needed steps. We will also provide you with a professional removal tool for self-help that will significantly speed up the removal process and save you tons of time.

For many people, the unauthorized changes in the browser’s homepage and the default search engine, accompanied by the unstoppable steam of pop-up ads and banners is a good enough reason to remove Paper Extension without thinking twice. However, this isn’t the only reason why this is a good idea.

The questionable quality of the ads that can be shown on the screen is also an issue with this type of software. Not all web advertisements are to be trusted, and many of them may not really redirect you to what they seem to promote, meaning that you might click on a particular pop-up thinking that it is a real deal only to land on some questionable website that may inject you with ransomware, a Trojan or some other virus. So it is very important to remain vigilant around Paper Extension and to ensure that the intrusive software is deleted as soon as possible.

Simply follow the steps outlined below to save time and make things more convenient:

  • Hold down the CTRL, SHIFT, and ESC keys at the same time.
  • In the Task Manager window, select the Processes tab from the tabs at the top (In Windows 8 and 10 it is called “Details”).
  • The Paper Extension process may or may not be the same as the browser hijacker in terms of name and description. Seek out signs of unusual activity, such as random processes or higher than usual CPU and memory utilization.
  • Right-click on any process that appears suspicious and select Open File Location from the context menu.

Then, using the powerful Free Virus Scanner offered here, scan the files for dangerous or potentially unwanted code:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy

    Wait for the scan to be completed and if the files contain potentially harmful code, end the process that is associated with them, then delete the files and their associated directories. You may need to repeat a file scan with another process that appears suspicious if necessary until you are 100 percent sure that your system is not being disrupted by any hijacker-associated activities.


    In this step, press the Windows and R keys on your keyboard at the same time. You’ll see a Run window appear on your screen. In the text box, type appwiz.cpl and press the OK button.


    A new window will open, displaying a list of all the applications currently installed on your computer. Filter the apps by the date they were installed, and pay particular attention to the most recent ones that were installed around the time Paper Extension began to cause you problems. If you suspect that any of these applications may have been responsible for the introduction of the browser hijacker into your system, make sure to uninstall them immediately.

    After that, go to the Start menu and type msconfig into the search field to launch System Configuration. After pressing Enter, select the Startup tab from the top tabs menu:


    Select any startup items that you believe may be connected to the ad-generation and page-redirection behavior you are experiencing, remove their checkmarks, and then click OK to save your changes.

    Attention! Don’t remove registry entries if you aren’t sure that they belong to the browser hijacker! Changes to the registry and removals from the registry can cause severe system corruption. Please make use of a professional removal instrument to avoid causing unwanted damage.

    If there are no results found through the search, navigate manually from the left panel of the Registry Editor to the following folders:

    • HKEY_CURRENT_USER—-Software—–Random Directory. Search for unusually-looking directories.
    • HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    • HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

    If you discover anything in any of these directories that is associated with Paper Extension, delete it. Again, take great caution and use a professional removal program if you aren’t sure what you should delete or don’t know where to start.

    Some browser hijackers are more persistent than others, and some are more difficult to remove. When dealing with Paper Extension manually, it is recommended that you scan your computer with the anti-virus software we recommend or check specific files with the free online virus scanner, to ensure that you are not infected with anything else. Aside from hijackers, such software may also address other potentially unwanted and hidden hazards that may interfere with the normal operation of your system, such as viruses., to ensure that you are not infected with anything else.
