Looker Extension

Looker Extension is a browser hijacking software component capable of modifying your Chrome, Firefox, or Edge browser and spamming it with ads without your permission. Looker Extension usually gets installed in the browser with the help of file bundles or misleading interactive browser pop-ups.

Looker

If the homepage and/or the default search engine of your browser has been changed to Looker Extension or another site without your approval, this is a sure sign that the browser has been infiltrated by a hijacker such as Looker Extension. The goal of such software components is primarily promotional – they earn money for their creators from Pay-Per-Click  ads and Pay-Per-View page-redirects, which is why it’s common for such apps to aggressively flood the infected browser with all sorts of obstructive advertising materials. While this won’t directly harm your system, it can potentially slow down the PC and also make it difficult to use your browser normally. 

However, an even bigger issue related to the aggressive promotional activities of apps like Looker Extension is that they can put your system at risk of getting attacked by malware. 

One of the reasons for this is most browser hijackers also make changes in the system itself – they modify the Registry, add new services and startup items, and create new files without the user’s permission. Those changes could potentially weaken the system’s security and make it vulnerable to attacks from Trojans, Ransomware, and other malicious threats. 

Furthermore, the ads themselves may sometimes promote questionable or outright harmful websites that could try to automatically download malware onto your computer.

Another unpleasant possibility is if the hijacker redirects you to a phishing page – if you are not careful and this happens, you may be tricked into sharing personal data such as your credit or debit card numbers or your logins to online accounts in which you’ve invested a good amount of money (for example, your Steam or Epic Games Store account).

Dealing with Looker Extension

It should be obvious by now that the only viable course of action if you have this hijacker attached to your browser is to get rid of the rogue app, as this is the only way to put an end to the barrage of ads and to restore your browser to its regular state.

. Doing so isn’t as straightforward as uninstalling any regular program, because most hijackers are designed to be difficult to fully delete. This is why we strongly recommend following the steps shown in the guide below, and also using the recommended anti-malware tool posted on this page. The tool specializes in detecting and eliminating rogue apps such as adware, and hijackers, but it can also keep you protected from more serious threats, including Trojans and Ransomware.

Once you’ve managed to get rid of Looker Extension or Bundle Extension, it is important to ensure to keep your computer protected and clean. Generally, if you ensure to avoid sketchy sites and interaction with questionable web content, your system should be reasonably safe. It’s also important to not download anything that’s not verified as safe and to always check the Advanced settings menu in software installers to see if there aren’t any bonus apps included there that you may not want to get installed on your computer.

Alternatively, if it is more convenient for you, you may choose to open the instructions on another device instead and follow them from there.

With regard to the computer restart we recommended in the beginning, please refer to this link for detailed information on how to boot into Safe Mode when restarting your computer. This may make it much easier to detect and remove the browser hijacker because Safe Mode allows you to run only the most basic applications and processes. This gives you more opportunity to spot anything unwanted or additional that shouldn’t be running on the system.

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

To access the processes now running on your system, you must first launch the Windows Task Manager by pressing CTRL, SHIFT, and ESC simultaneously. Next, click the Processes tab, and look for any processes that have strange names, processes that consume a significant amount of CPU or RAM, or processes that are responsible for tasks like ad generation or page redirection, among other things. Processes having Looker Extension in their names can also be found using this method.

When you right-click on a suspicious process, you will be able to select Open File Location from the fast menu and inspect the files associated with that process.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    If your scanner identifies a potential danger in one or more of the scanned files, the best course of action is to delete those files from their original file location folder. Nonetheless, if the process is still operating in the background, this may not be possible. You must thus return to the Processes tab and right-click on the currently selected process, then choose End Process from the shortcut menu, in order to complete this task. It will be possible to remove the files after that by returning to their original location in the folder where they were originally placed.

    Step3

    In the third step, launch a Run window by pressing the Windows and R keys at the same time, as seen in the image below. After that, type appwiz.cpl in the Run box, and press the Enter key to run the following command:

    appwiz

    You should see a list of all of the apps that have been installed on your computer in a new Control Panel window.

After that, you should remove any hijacker-related software that you discover in there by selecting it with your cursor and clicking on the Uninstall button located at the top of the window. The Control Panel window should be closed once all potentially unwanted applications have been removed.

    Next, navigate to the Windows search field and carefully type msconfig in it, then press the Enter key on your keyboard. In Windows 10, the search field is marked as a magnifying glass icon in the bottom left corner next to the Windows menu button.

    Step5

    One of the most critical steps in this guide is to search the registry for entries that belong to the browser hijacker. To begin, type regedit in the Windows search field and click Enter. The Registry Editor will be launched as a result of this action.

    By pressing the CTRL and F keys at the same time, you can open a Find dialog box where you can type the name of the browser hijacker that is disturbing you. Find Next can help you discover the browser hijacker entries that are matching its name. Any discovered entries should be erased by right-clicking on them and selecting “Delete”. Repeat the search as many times as necessary until there are no more results.

    We also recommend you to manually go to the Editor’s left panel and navigate to each of the following locations:

    • HKEY_CURRENT_USER—-Software—–Random Directory.
    • HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    • HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

    It is crucial to remember that deleting Registry entries from your computer may result in problems for your ящяшеп and its programs, especially if it is done incorrectly. In order to prevent causing harm to your computer’s software, you should use professional removal tolls, such as the one provided on this page, or another reputable program of your choosing to remove the virus.
