Archster is categorized as a website with browser hijacker characteristics. It changes some of the browser settings and installs new components in the browser with the aim to boost the traffic to certain pages by redirecting the user to them. There are many types of unwanted apps that, while not necessarily harmful to the system, can still make your computer less optimized and browser hijackers like Archster are an example.

What is Archster?

A browser hijacker, like Archster, is a piece of software that operates from inside popular browsing programs like Firefox and Chrome. Its main goal is to modify the browser in order to show different ads in it and to redirect the user to some specific sites with the goal to improve their view counts. While this may sound rather innocent, once you start seeing the changes in the homepage, the toolbar, or the search engine of your main browser, and once the ads and the page-redirects start swarming your screen you are likely going to want to uninstall the obtrusive app. Uninstalling a hijacker like Archster, however, might be quite a tricky task because most applications of this type lack the regular uninstallation options that normal programs and apps have.

The Archster Virus

You may see people referring to the browser hijacker that we are talking about as the “Archster virus”. However, the “Archster virus” isn’t really a harmful program in the same way as Trojans and Ransomware viruses are. It is more of an unwanted software that annoys the users rather than an actual system hazard. Despite that, hijackers could potentially sometimes get you into trouble. Their tendency to spam you with all kinds of obscure ads and to automatically redirect you to web addresses you did not intend to visit could be regarded as dangerous behavior. You could potentially land on phishing sites, pages that try to sell you fake products or software, or even sites that have Trojans, Spyware, and Ransomware uploaded to them. With this in mind, it really is the better option to stay away from any content that Archster, and similar programs like Your Search Bar, may show on your screen.

Archster on Chrome

You are likely to not find an actual uninstallation executable for Archster on Chrome, and you will probably not see an entry for it in the Control Panel’s uninstallation list or in the extensions’ menu in the browser. And in the rare cases you do, using any of these to uninstall the unwanted app may prove to be unsuccessfull, as most hijackers install extra elements in the system that allow them to come back even after having been uninstalled. This difficult uninstallation, combined with the rather aggressive advertising techniques used by most such apps, and their overall lack of useful functions, is what leads many users to refer to them as viruses. Redirects is the website, related to the browser hijacker that is causing intrusive ads on your screen. It jeopardizes online safety by spamming devices with unwanted content and redirects. Therefore, to protect your system, we recommend you to use a removal guide to eliminate quickly and effectively. If you follow the instructions below, you can restore your browsing experience and prevent potential security risks associated with its presence.

Next, Reboot in Safe Mode (use this guide if you don’t know how to do it).

Step1 Uninstall the Archster app and kill its processes

The first thing you must try to do is look for any sketchy installs on your computer and uninstall anything you think may come from Archster. After that, you’ll also need to get rid of any processes that may be related to the unwanted app by searching for them in the Task Manager.

Note that sometimes an app, especially a rogue one, may ask you to install something else or keep some of its data (such as settings files) on your PC – never agree to that when trying to delete a potentially rogue software. You need to make sure that everything is removed from your PC to get rid of the malware. Also, if you aren’t allowed to go through with the uninstallation, proceed with the guide, and try again after you’ve completed everything else.

  • Uninstalling the rogue app
  • Killing any rogue processes

Type Apps & Features in the Start Menu, open the first result, sort the list of apps by date, and look for suspicious recently installed entries.

Click on anything you think could be linked to Archster, then select uninstall, and follow the prompts to delete the app.

Press Ctrl + Shift + Esc, click More Details (if it’s not already clicked), and look for suspicious entries that may be linked to Archster.

If you come across a questionable process, right-click it, click Open File Location, scan the files with the free online malware scanner shown below, and then delete anything that gets flagged as a threat.

    Delete Archster files and quit its processes.

    After that, if the rogue process is still visible in the Task Manager, right-click it again and select End Process.

    Step2 Undo Archster changes made to different system settings

    It’s possible that Archster has affected various parts of your system, making changes to their settings. This can enable the malware to stay on the computer or automatically reinstall itself after you’ve seemingly deleted it. Therefore, you need to check the following elements by going to the Start Menu, searching for specific system elements that may have been affected, and pressing Enter to open them and see if anything has been changed there without your approval. Then you must undo any unwanted changes made to these settings in the way shown below:

    • DNS
    • Hosts
    • Startup
    • Task
    • Services
    • Registry

    Type in Start Menu: View network connections

    Right-click on your primary network, go to Properties, and do this:

    Undo DNS changes made by Archster

    Type in Start Menu: C:\Windows\System32\drivers\etc\hosts

    Delete Archster IPs from Hosts

    Type in the Start Menu: Startup apps

    Archster startup apps

    Type in the Start Menu: Task Scheduler

    Delete Archster scheduled tasks

    Type in the Start Menu: Services

    Disable Archster services

    Type in the Start Menu: Registry Editor

    Press Ctrl + F to open the search window

    Clear the Registry from Archster items

    Step3 Remove Archster from your browsers

    • Delete Archster from Chrome
    • Delete Archster from Firefox
    • Delete Archster from Edge
    1. Go to the Chrome menu > More tools > Extensions, and toggle off and Remove any unwanted extensions.
    2. Next, in the Chrome Menu, go to Settings > Privacy and security > Clear browsing data > Advanced. Tick everything except Passwords and click OK.
    3. Go to Privacy & Security > Site Settings > Notifications and delete any suspicious sites that are allowed to send you notifications. Do the same in Site Settings > Pop-ups and redirects.
    4. Go to Appearance and if there’s a suspicious URL in the Custom web address field, delete it.
    1. Firefox menu, go to Add-ons and themes > Extensions, toggle off any questionable extensions, click their three-dots menu, and click Remove.
    2. Open Settings from the Firefox menu, go to Privacy & Security > Clear Data, and click Clear.
    3. Scroll down to Permissions, click Settings on each permission, and delete from it any questionable sites.
    4. Go to the Home tab, see if there’s a suspicious URL in the Homepage and new windows field, and delete it.
    1. Open the browser menu, go to Extensions, click Manage Extensions, and Disable and Remove any rogue items.
    2. From the browser menu, click Settings > Privacy, searches, and services > Choose what to clear, check all boxes except Passwords, and click Clear now.
    3. Go to the Cookies and site permissions tab, check each type of permission for permitted rogue sites, and delete them.
    4. Open the Start, home, and new tabs section, and if there’s a rogue URL under Home button, delete it.
