There are many times when you have to change the ownership of a folder or a file so that other users can use them as well or if you want to transfer files to them, or an old account has been removed and all the files need to be assigned to a new user. Windows 10 keeps all these files locked under the account by default which created a folder or file. So unless a user is an admin or if the file belongs to that particular user, other users won’t be able to access or edit the file. So if you want to change the ownership of a folder or a file, then you’ve come to the right place as this post will guide you on how exactly you can do that.

To get started, make sure to follow the instructions provided below carefully.

Step 1: First, you need to open File Explorer by tapping the Win + E keys. Once you’ve opened it, navigate to the folder or file that you want to change the ownership. Step 2: Right-click on the folder or file and click on Properties and then go to the Security tab. Step 3: From there, click on the Advanced button located at the bottom right part of the window to open the Advanced Security Settings of the folder or file. Step 4: As you can see, the current owner will be listed with the Change link available next to the “Owner” label. Now click on this link to open the Select User or Group window. Step 5: After that, click on the Advanced button once again and click on the “Find Now” button to see the list of all the users as well as groups that are available in the computer. Step 6: Then select the user you want to give ownership to and click on the OK button and then click the OK button once more to save the changes made. Step 7: This will take you back to the Advanced Security Settings window but this time, the owner will be changed to whoever user you’ve selected. But you’re not done yet as you still have to check two additional options to help you completely transfer the ownership of the sub-folders as well as the files. You have to check the checkbox of the following options:

• Replace owner on sub-containers and objects
• Replace all child permission entries with inheritable permission entries from the object.

Step 8: After that, you need to click the Apply and OK buttons to confirm and save the changes made. This will completely transfer the ownership of the file. However, there is still one last thing you have to do – you have to go back to the Advanced Security Settings window to remove the access of any other user on the folder or file. Once you’re there, remove the existing user to make sure that the only assigned user has the access to the folder or file.

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.

At this point, you can actually run the antivirus scan to get rid of viruses and malware without any interference from another malicious application.

Switch to an alternate internet browser

Some viruses might target vulnerabilities of a specific browser that obstruct the downloading process. If you seem to have a trojan attached to Internet Explorer, then switch to an alternate browser with built-in security features, such as Firefox or Chrome, to download your favorite antivirus program – Safebytes.

In case you don’t know, a teletype network, also known as Telnet, is a protocol that is meant for internet or LAN communication which is used primarily to control other computers effortlessly. And it is available as a command-line utility in Windows and helps users in opening a command-line interface for the remote computer. However, a lot of users have reported an error that states, “Telnet is not recognized as an internal or external command, operable program, or batch file” when you try to use it. If you are one of these users, then you’ve come to the right place as this post will guide you on how to fix this error in Windows 10. This kind of error means that the Telnet utility is not installed on your computer but Telnet is a default feature in Windows 10 so the protocol mainly is not enabled yet. The Telnet client is disabled by default in Windows 10 and to fix this error, you can try to enable the Telnet Client via Programs and Features or try to install Telnet using an elevated Command Prompt.

Option 1 – Try to enable the Telnet Client via Programs and Features

The first thing you can do is to enable the Telnet client using Programs and Features since it is disabled by default. To do that, follow the steps below.

• Tap the Win + R keys to open the Run dialog box and type “appwiz.cpl” in the field and hit Enter to open the Programs and Features window.
• Next, select the “Turn Windows features on or off” from the options given on the left-hand side.
• After that, look for the Telnet client from the list and check the checkbox next to it and then click on OK to save the changes made.
• Now restart your computer.

Option 2 – Try to install Telnet via an elevated Command Prompt

If enabling the Telnet client using Programs and Features didn’t work, then you can try to do it using Command Prompt instead. To get started, follow the steps given below.

• In the Windows Search bar, type “command prompt” in the field and right-click on Command Prompt from the search results, and select the “Run as administrator” option.
• Next, execute this command to enable the Telnet client: dism /online /Enable-Feature /FeatureName:TelnetClient

If you notice that your tabs in your Firefox browser keep on crashing recently, then there might be something wrong with your browser. Every time any of your tabs crashes, you might encounter an error message saying, “Gah, Your tab just crashed”. If you encounter this kind of error message then it is most likely that your Firefox Profile is having some issues with the existing installation of Firefox. The “Gah, Your tab just crashed” error rarely happens but when it does, it can get quite annoying as you won’t get to browse the internet peacefully. So to fix it, here are some suggestions you could check out.

Option 1 – Try disabling multi-process tabs in Firefox

Since Mozilla has one process for Firefox itself, while one process handles all the tabs, you have the option to disable these multi-process tabs in Firefox. To do that, follow these steps:

• In the address bar of Firefox, type “about: config” and hit Enter.
• Next, look for the following configurations and set them to false.
  • tabs.remote.autostart = false
  • tabs.remote.autostart.2 = false
• After that, double-click on the toggle switch between true and false.

Option 2 – Try checking your Add-ons

In this option, you need to start Firefox in Safe Mode and then check if the problem is fixed. If it is, you may have to check your Firefox add-ons as well as extensions as one of them might be the one that's causing the “Gah, Your tab just crashed” error.

Option 3 – Downgrade the Firefox version you’re using

It could be that the current version of Firefox you’re using has some issues so you might have to downgrade it, especially if you are already using the latest version. To downgrade your Firefox browser, go to the directory of the other versions and languages and select an older version that worked for you. After that, you have to disable automatic Firefox updates.

• First, click the menu button and select Preferences.
• Next, go to the Firefox Updates section under the General panel.
• Then select the radio button labeled “Check for updates but let you choose to install them”. This will ensure that you will not have the same issue with the new update.

Note that this is only a temporary fix since updating your programs, including browsers.

Option 4 – Try sending Crash Reports

You might want to send crash reports to Mozilla. This way, Mozilla might come up with some fix to resolve the problem. All you have to do is type “about: crashes” in the address bar. This will list all the crash reports. Now send it to Mozilla using the built-in interface. Although this won’t instantly fix the problem, a lot of user finds it useful. And besides, the issue will get fixed in future releases or with minor updates.
