Gaming Wonderland is a Browser Extension for Google Chrome developed by Mindspark. This extension allows you to look up some popular browser games, as well as to find multiplayer games. When installed it changes your default search provider and your default home page to MyWebSearch. While browsing the internet, this extension will gather your browsing information, website visits, clicks, and other information that is later sent to Mindspark ad servers and used to better target ads.

While using this extension you will see additional unwanted ads appearing throughout your browser sessions.

Due to the nature of this application and the fact that it has been marked as a Browser Hijacker by several anti-virus scanners, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijacking means that a malicious code has power over and modified the settings of your internet browser, without your consent. They are made to disrupt browser functions for a variety of reasons. These are generally used to force visitors to a specific site, manipulating web traffic to generate ad revenue. It may appear harmless, but the majority of such sites are not legitimate and will present a serious risk to your online safety. As soon as the program attacks your computer or laptop, it begins to mess things up a whole that slows your system down to a crawl. In the worse case, you could be pushed to tackle serious malware threats as well.

Browser hijacking symptoms

When your web browser is hijacked, the following could happen: you find unauthorized modifications to your web browser’s home-page; new bookmarks pointing to pornographic websites have been added to your bookmarks; default web engine is changed; you are finding browser toolbars you haven’t noticed before; unstoppable flurries of popup advertisements show up on your PC screen; your browser gets slow, buggy, crashes quite often; you’re prohibited access to specific websites, including the site of an anti-malware software firm like SafeBytes.

How does a browser hijacker infect a PC

Browser hijackers might use drive-by downloads or file-sharing websites or even an e-mail attachment in order to reach a targeted computer. They could also be deployed through the installation of a web browser toolbar, add-on, or extension. A browser hijacker can also be installed as a part of freeware, shareware, demoware, and pirated programs. A good example of a notorious browser hijacker is the latest Chinese malicious software called “Fireball”, which has attacked 250 million PCs worldwide. It works as a hijacker but can be turned into a fully functioning malware downloader later on. Browser hijackers will affect the user’s browsing experience severely, keep track of the websites visited by users and steal private information, cause problems in connecting to the net, and eventually create stability issues, making applications and computers freeze.

Browser Hijacker Malware – Removal

Some kinds of browser hijackers can be removed from your computer by deleting malicious software applications or any other recently added shareware. At times, it can be a tough task to discover and get rid of the malicious component since the associated file might be running as part of the operating system process. Novice PC users should not try for the manual form of removal, since it calls for thorough computer knowledge to do fixes on the system registry and HOSTS file. Installing and running antivirus applications on the affected system will automatically erase browser hijackers and also other unwanted applications. Safebytes Anti-Malware incorporates a cutting-edge anti-malware engine that will help you prevent browser hijacker infection in the first place, and clean up any existing problems. Use a system optimizer together with your antivirus software to fix various registry problems, remove system vulnerabilities, and boost your computer's overall performance.

A lot of users connect to the internet are using VPN on their Windows 10 computers which means that their regions could be different from the actual region of their Windows 10 computers. Thus, if you are facing some issues in updating your computer in this kind of environment, specifically the Windows Update error 0x800F0922, you need to follow the tips given in this guide to help you resolve the issue. When you encounter this kind of Windows Update error, you might see either of the following error messages on your screen:

“Windows could not search for updates, Code 0x800F0922 Windows Update encountered an unknown error” Or: “Windows failed to install the update with error 0x800F0922”

This issue might be caused by two possible reasons such as:

1. VPN issues
2. Not enough space on the System Reserved partition

To resolve the problem, here are some tips that might help:

Option 1 – Try disabling the VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 2 – Try to free up space in the System Reserved partition

The System Reserved partition is a part of the hard disk created when Windows is first installed on it. It is where the Boot Configuration Database, Boot Manager Code, Windows Recovery Environment, and the reserves space for the startup files are stored. And as mentioned early on, the error might be due to some insufficient space in the System Reserved partition so the next thing you can do is to increase the space in this partition. Note that it is a complex process so you need to make sure that you have made backups to all your data on the computer. So if ever something goes out of hand, at least you have copies of your important files in case you aren’t able to boot into the system at all.

For example, the classic Windows Command Prompt can’t see emoji characters in file names properly, but both PowerShell and Microsoft’s new Windows Terminal can display them properly. If you do run into a problem, you can always open File Explorer and rename the affected files and folders to remove the emoji characters. You can then use those files in applications that don’t properly support emoji file names.

As you already know, the Windows Sandbox is one of the new features in Windows 10. However, just like other new features, it also throws up errors and one of them is the error that states,

“Windows Sandbox failed to start, Error 0x80070057, The parameter is incorrect”.

This particular error in Windows Sandbox occurs due to its dependence on numerous components of Windows 10 that are related to Hyper-V and Virtualization mainly. To fix this error, there are several options you can check out. You can try to install any pending updates on your Windows 10 computer, as well as make sure that all the services related to Windows Sandbox are enabled.

Option 1 – Try to run the Windows Updates to install pending updates

The first thing you can do to resolve the “Windows Sandbox failed to start, Error 0x80070057” is to check Windows Updates in your computer and see if there are any pending Windows Updates you have to install. All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox error.

Option 2 – Ensure that all the supporting processes and services are running properly

If running Windows Sandbox as an administrator didn’t fix the error, you have to ensure that all related processes for Windows Sandbox are running properly. To do that, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
