We have classified Accoona.com as a browser hijacker because it has the ability to change the default search engine, such as Google, and redirect all search queries to its own website, which benefits the virus author.
It redirects all browser requests to Accoona.com and, for some reason, is difficult to remove for the average user whose browsers have been infected by this virus.
Browser hijackers in general
Browser hijackers are exactly what their name implies. They use malicious code to take over the infected computer’s web browser.
These include changing the default home page, appearance, and search engine to aggressively promote their unwanted website without the user’s knowledge.
Unwanted advertisements and affiliate links are introduced into the browser by directing the user’s searches to a sponsored search engine.
They control this search engine, which displays advertisement links rather than legitimate search results.
As previously stated, Accoona.com is a browser hijacker that directs searches to their website instead of the default search engine.
This type of threat is particularly concerning because it not only produces poor search results, but also allows the virus to monitor and track the infected computer’s browsing activities.
Accoona.com threat behavior
After a thorough investigation in a controlled malware-testing environment, we observed the following behavior on Accoona.com:
The browser’s default search engine and home tab will be updated to prioritize Accoona.com over the current search engine.
When we used the aforementioned website to search, we discovered that it only returned a small number of results. This means that any unfamiliar terms may not appear in the search results.
When you visit the website directly, it disguises itself as a listing directory website for many different categories of famous locations.
Unlike browser hijackers like Search-load.com and Api.global-data-lab.com, it does not send users to Bing or Yahoo.
Instead, it uses a web search API to display unwanted affiliate links and sponsored results alongside the search results.
This means that when users search for something, the first links they see are sponsored links designed to entice users to click on them, thereby benefiting malware authors.
It is also particularly similar to malicious browser hijackers such as Maxask.com, Boyu.com.tr, and Skyjem.com.
Accoona.com is not caused by browser extensions, but rather by malware that changes the browser’s search engine settings.
These settings are easily changed in the browser’s settings, unless the browser is managed by an organisation.
Cybercriminals frequently use browser policies to install a search engine on infected computers.
We discovered that it is linked to a trojan virus called InternetGuardian (IGuardian.exe) and TenBrowser, which is responsible for the Accoona.com browser hijack.
Distribution network
The malicious browser hijacker, like other malware, infects computers and browsers by injecting itself into fake download links found on torrenting sites and untrustworthy software download platforms.
Unfortunately, many people become victims of these common scams after clicking the download button on a deceptive website.
Browser hijacker infestations frequently occur when users attempt to download files from hosting services that bombard them with excessive advertising.
The image above depicts a deceptive download page from a dangerous torrenting website that includes the Accoona.com browser hijacker and other malicious payloads.

This part onwards will show you how to do that. Please make sure you follow the steps exactly to get rid of the malware threat.
We considered the technical skills of the people who use the internet, so we made sure the steps are simple enough that even those who aren’t tech-savvy could follow them.
Before you continue, make sure you have a backup of your data saved somewhere. If you don’t, your files may be destroyed or lost as you follow the procedures below. These situations are uncommon, but we recommend taking precautions just in case.
To remove the Accoona.com hijacker virus from your browser, you only need to follow a simple four-step procedure:
Step 1: Delete the malicious extension
Extensions can be the leading cause of Accoona.com causing issues with the browser. However, it may be difficult to remove them if certain browser policies are set to make it persist. It might disable the delete button which makes it hard to do so.
For this reason, we will first need to delete the policies it has set on the browser before attempting to remove unwanted extensions.
- Google Chrome
- Mozilla Firefox
- Microsoft Edge
How to remove Google Chrome browser policies:
1. To do this, we will use Chrome Policy Remover. Download the Windows version by clicking here.
2. Proceed to download delete_chrome_policies.bat by clicking Download anyway.
3. Once the bat file has finished downloading, run it as administrator to begin removing unwanted policies set by the malware.
4. If the Microsoft Defender SmartScreen prevented it from running, click Run anyway. This tool has been recommended enough times in the Google Chrome community therefore we can vouch that it is safe to run. (VirusTotal results of the Policy Remover.)
5. The command prompt will open up, it will close Chrome and delete certain malicious policies. Once the policies are removed, you can now close the command prompt and begin removing the extension.
1. Open the Windows start menu and type Registry Editor.
2. Right-click the first result and select Run as Administrator.
3. In the Registry Editor, go to the following keys and delete each folder one by one:
HKEY_CURRENT_USER\Software\Google\ChromeHKEY_CURRENT_USER\Software\Policies\Google\Chrome
HKEY_LOCAL_MACHINE\Software\Google\Chrome
HKEY_LOCAL_MACHINE\Software\Policies\Google\Chrome
HKEY_LOCAL_MACHINE\Software\Policies\Google\Update
HKEY_LOCAL_MACHINE\Software\WOW6432Node\Google\Enrollment
4. We are not done yet, head over to the following registry key:
HKEY_LOCAL_MACHINE\Software\WOW6432Node\Google\Update\ClientState{430FD4D0-B729-4F61-AA34-91526481799D}
5. Find and delete the value named CloudManagementEnrollmentToken.
6. Lastly, open the File Explorer program and paste the following to the address bar:
%ProgramFiles(x86)%\Google\Policies
7. Select and delete the Policies folder if there is one present.
Following that, close and reopen Google Chrome and the enterprise policy should have been removed.
How to delete unwanted extensions from Chrome:
1. Open Google Chrome and click the three horizontal dots on the upper-right corner of the screen.
2. From the dropdown menu, select Extensions and click Manage Extensions.
3. You should now be able to click the Remove button. Continue to do so in order to remove the unwanted extension from the browser. (For this example, we will be using Google Docs Offline.)

1. Open Microsoft Edge and click the Extensions icon on the top bar of the browser.
2. Click on Manage Extensions.
3. Find the unwanted extension and click Remove.
Step 2: Remove browser malware with AdwCleaner
AdwCleaner is a utility tool that is primarily used for cleaning adware and potentially unwanted applications (PUP) from the computer.
This program is also primarily used to find and remove malware that is targeted at the web browser.
Here’s how to install and use AdwCleaner:
1. To start, download the latest version of AdwCleaner.
2. Once AdwCleaner has finished downloading (adwcleaner.exe), run the executable file.

4. Once the program has launched, agree to the End User License Agreement by clicking the I Agree button.
5. Click on the Scan Now button to begin scanning your computer for browser threats such as adware, PUPs, and more.
6. Wait for AdwCleaner to finish scanning the files on the system. This may take a while depending on how large the files on your device are, as well as your system’s hardware capabilities.
7. Once the scan is complete, proceed to take action by following the on-screen instructions. Otherwise, if the scan shows a clean result, click Run Basic Repair to reset Winsock and other settings before finishing the process.
Step 3: Uninstall unwanted software
Another possible source of the Accoona.com browser hijacker is malicious software.
Such malware might be able to change browser settings in order to support the aforementioned browser threat. As a result, you should check your computer for unknown programs that you did not install.
While the latest version of Windows allows you to accomplish this through the Add & Remove Programs section, it is still far simpler to use the Programs and Features page in the Control Panel.
The publisher name, the installation date, and the version number will all be displayed in a single grid screen, making it simpler to locate the malware. Here’s how to do so:
1. Click on the Windows key to open the Start menu.
2. Type Control Panel in the provided search bar and select the first item from the search results.
3. Click on Programs and inside, select Programs and Features.
4. You will be presented with a list of programs currently installed on your computer.
5. Find programs you do not recognize and right-click the item then select Uninstall/Change from the dropdown menu.
We’ll need to use a powerful uninstaller to do the dirty work for us if the software is stubborn and won’t go away with normal approaches.
Fortunately, there are tools for this; Revo Uninstaller is a good uninstaller program made to tackle and remove uninstallable programs.
Uninstall malicious program/s using Revo Uninstaller1. To start, download Revo Uninstaller by clicking here. Avoid downloading from third-party sources as they may contain additional bloatware upon installation.
2. On the download page, opt for the free version of Revo Uninstaller as it has all the features we need. Click on Free Download to begin downloading the setup file.
3. The revosetup.exe file would have started downloading. Click on it to start installing the software.
4. Revo Uninstaller setup would now begin and follow the typical setup procedure such as selecting your setup language, accepting the license agreement, and selecting the installation location. Once setup is ready click Install.
5. After the setup is finished, check the Launch Revo Uninstaller option to open the program upon closing the installer.
6. Once Revo Uninstaller has opened, it will show you the list of applications currently installed on the computer. Find the unwanted program/s, right-click it, and select Uninstall from the drop-down menu. (We will be using PC App Store to demonstrate.)
7. A confirmation message stating if you are sure you want to uninstall the said program, click Continue.
8. Follow the uninstallation instructions and this time, Revo Uninstaller would have forced the program to continue with the uninstallation compared to the previous attempt via Control Panel.
9. You will be notified that the software has been uninstalled, Revo Uninstaller will now conduct a preliminary examination and get rid of additional files and registries related to the unwanted program.
10. On the selection of Scanning modes, select Advanced to make sure everything is scanned without leaving a single directory unnoticed.
11. Wait for the scan to finish as Revo Uninstaller is checking for residual files and registries related to the suspicious program.
12. Revo Uninstaller may have found leftover Registry items, click Select All and proceed to delete them by clicking the Delete button next to it. After that, click Next.
13. It may have also found some leftover files and folders, simply do the same by clicking Select All and deleting them. Now click Finish and the uninstallation of the program is done.
Step 4: Run additional malware scans
Antivirus engines may not detect new threats in the early stages of infection due to the malware not yet being recognized by the security software. It might be discovered in the end, but it may be too late for the infected machines.
However, new malware threats may contain strings and signatures from previous malware in a database of existing security products. As a result, other antivirus software may identify it while others do not.
Since some antivirus software may not be able to detect it, we’ll need more than one piece of security software to help us locate and remove the harmful threat.
Please run the software individually. You can do so in any particular order.

Browser protection tips
As the saying goes: “The biggest vulnerability is the person behind the screen“
So, here are some tips and what you need to know in order to keep your device safe and malware-free in the long run.
Keep every software installed up to date
Make sure that all of the programs in your computer is up-to-date with the latest version released by the developer. The reason behind this is that these updates frequently tackle bugs and issues that malware actors often exploit.
The same goes for your computer’s operating system, make sure Windows is up-to-date with the latest software update to prevent malware from exploiting a hidden vulnerability.
Avoid downloading files from unknown sources
One of the biggest sources of malware infection in a computer system is third-party installations. This happens when a user downloads a certain program from sources that are not the official download links. Some of the common types of sources where malware is present are torrent files, cracked software, and games.
Be careful with opening email attachments
Malware often disguises itself as resumes and quotations and threat actors often send thousands of these infected emails to company employees around the world in order to infiltrate their network.
Always check where your emails are coming from as there may be a chance that the project attachment you received via email did not actually come from a co-worker.
Do not visit unreputable websites
Avoid visiting websites that contain unfiltered advertisements such as illegal streaming websites, cracked software platforms, and links sent out to you by somebody you do not trust.
These sites are often linked to redirect chains that load once you click on an ad element on the page. Following this chain often leads to drive-by malware and phishing pages that an average user may eventually fail to notice.
