What is Search.schooldozer.com? And how does it function?

Search.schooldozer.com is a browser extension that functions as a search engine. It is developed and maintained by “Schooldozer”. It claims to improve users’ browsing experience by providing them with improved search results. However, it does not really do the things it claims to do. In fact, they’re quite the opposite ones – instead of improving the browsing experience, it makes users’ browsing experience unsafe and full of sponsored content. This is in contrast to what it states in its Privacy Policy:

“Install applications the easy way and without the hassle, using the Schooldozer downloader. The Schooldozer platform stems from years of experience with installing applications, resulting in a highly optimized process, yielding faster downloads, better user experience, and more successful installations.”

In addition, once installed Search.schooldozer.com is installed, it will change the default settings of a browser such as the default search engine, homepage, and new tab page. This is why security experts regard this browser extension as a browser hijacker and a potentially unwanted program. The modification of the browser's settings allows it to control users’ browsing by redirecting them to sponsored sites as well as deliver sponsored content from its affiliated sites in order to gain profit via pay-per-click marketing. And if you think that the ads it displays are harmless, think again for some of these ads can redirect you to suspicious websites that might contain harmful content. What’s more is that this browser hijacker can also keep track and monitor all your browsing activities in order to obtain your browsing data like search queries, what sites you always visit, browsing history, browser type, OS version, and so on. The information collected is then used and may even be shared with its affiliated third parties to deliver more customized and personalized advertisements.

How is Search.schooldozer.com distributed over the web?

Like a typical browser hijacker, Search.schooldozer.com is distributed using the software bundling method where several unknown and unwanted programs are bundled in a software package. Thus when you install any software bundle, make sure to always opt for the Custom or Advanced installation setup rather than the quick setup to avoid installing unwanted programs like Search.schooldozer.com. To remove Search.schooldozer.com from your computer, follow the removal guide below carefully. Step 1: Start the removal process by closing all the browsers infected with Search.schooldozer.com. If you’re having a hard time closing them, you can close them using the Task Manager just tap on Ctrl + Shift + Esc. Step 2: After you open the Task Manager, go to the Processes tab and look for the infected browser’s process and end it. Step 3: Then close the Task Manager and tap the Win + R keys to open Run and then type in appwiz.cpl to open Programs & Features in Control Panel. Step 4: From there, look for Search.schooldozer.com or any unfamiliar program that could be related to it under the list of installed programs and once you’ve found it, uninstall it. Step 5: Edit your Hosts File.

• Tap the Win + R keys to open then type in %WinDir% and then click OK.
• Go to System32/drivers/etc.

If you are trying to copy a folder or file in your Windows 10 computer but encountered an error that says, “There is insufficient disk space to complete operation”, then you’ve come to the right place as this post will walk you through how you can fix the error. This kind of problem could be due to lack of disk space, corrupted disk, and many more. In such cases, this error usually pops up when you move or copy a file or folder to a particular location. There are several potential fixes you can check out to fix this error. You can try to run the Storage Sense or Disk Cleanup or try copying or moving the file in a Clean Boot State. You could also try formatting the given partition to NTFS. For more information, refer to each one of the options provided below.

Option 1 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the “There is insufficient disk space to complete operation” error.

Option 2 – Restart your computer in a Clean Boot State

If the first options didn’t work and you still see the “There is insufficient disk space to complete operation” error when you copy folder or files, you can try putting your computer in a Clean Boot State and then again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect copy the folder or file once more and check if the error is now gone.

Option 3 – Try formatting the given partition to NTFS

Even though this option may take a lot of your time, it is proven to fix the “There is insufficient disk space to complete operation” error as reported by many users who also went through the same dilemma. So if the removable disk is showing the same error message no matter which computer you insert it, you might have to format the drive with the help of Command Prompt. But before you do that, you must know that all the contents of your drive will be permanently deleted after you format it.

• Tap Win + R to launch Run.
• Type in cmd and then tap Enter or click OK to open the Command Prompt.
• And in the elevated window of Command Prompt, type in the following command:

format F: /fs:ntfs

In the command given above, “F” is the drive letter and “NTFS” is the file system you want. Just remember to replace “F” with the drive letter you want to format as well as the file system you prefer. Brace yourself as this process might take quite a while even if you only have a 4 GB USB drive – so you must not close the window under any circumstances as the drive might get corrupted and wait for the process to finish.

The author of the famous software library mode-ipc that gets over a million downloads per week found that it has some questionable code inside. The code itself behaves like this: if it finds out that your location is within Russia or Belarus it will try to replace the contents of all files on the computer with a heart emoji.

One important thing is that we here are not supporting the current Ukrainian situation and are against any type of violence or war but we also do not support this kind of behavior as well. If we look at this only from a technical perspective, we would then classify the mode-ipc library as malware and a harmful piece of code no matter the motivation behind it.

So this so-called protestware is well basically malware, but not always, it will protest when certain conditions are met. The issue with this is that companies and users should not be placed under harm if they do not share the personal view of the code author. Imagine if, for example, I would publish code to delete all pictures from your computer if my code found out that you do not like metal music. I guess you not liking metal music and war in Ukraine are two very different things but the source is the same, unreliable code that invades your privacy in order to serve one purpose, punishment for disagreeing with my personal views and that should not be allowed.

Not all protestware are equal, some will not harm your computer on purpose, they will just annoy you with some messages like viruses did in their infancy stages, others might place some developer sanctions but no matter the outcome basic principle is the same, it does something without user consent and without informing the user that something like that might happen.

On the internet, many blog posts and discussions were open about this issue and its morality. Discussion is still active with different takes on the situation and how to prevent it. Our take on this matter is that professional developers should have standards and not submit to doing harm for the sake of personal views and feelings.

In the long run, this kind of behavior and practice can only harm developers involved in this kind of entanglement. Infected libraries will in time stop being used since people would not trust them and authors will have a stain on their name as impulsive or not trustworthy.

Cache files are temporary files that have been created by various applications and services when used.  As temporary files, they are safe to be removed and deleted from the system since the application or service will create new ones when needed but sadly will not remove old ones, this task is left to OS itself. Automatic Windows cleanups can mostly take care of these things but for top-notch performance clearing cache manually is a far better option. We will here explore various cache temporary files, where they are, and how to clean them. Sit back and let’s do some cleaning!

Clear cache using Disk Cleanup

1. Open Start menu and search Disk Cleanup
2. Click on it in search results
3. Click on the drives drop-down menu and select the drive where is Windows 11 installed
4. In the Files to Delete section enable all boxes and click on OK
5. Click on delete Files to confirm

Clear Microsoft store cache

1. Press ⊞ WINDOWS + R to open the run dialog
2. Type in WSReset.exe and press ENTER
3. Black blank windows will appear, wait for the window to close itself and you are done

Clearing location cache

1. Press ⊞ WINDOWS + I to open location history
2. Select Privacy & Security
3. In the App Permissions section click on Location
4. On-Location page click on Clear

Clear and flush DNS

1. Press Start and search for Windows Terminal
2. Click on Terminal in search results
3. Type in: ipconfig /flushdns and press ENTER

And that is that!

In case you don’t know, the .Net Framework is a programming infrastructure introduced by Microsoft. You will need it to run on lots of services and applications. Note that most of the applications that require the .Net Framework are packed with their installation files which is why it will be installed automatically on your computer when you install an application. However, there are instances when you’ll get an error message saying, “The .NET Framework 4.7 is not supported on this operating system” while trying to install the .NET Framework as a standalone service. The very reason why this error message appears is stated in the error message itself. Although the .Net Framework is supported on Windows 10, it is not actually compatible with some other Windows 10 versions. So it is most likely that you are seeing this error message because the .Net Framework in your computer is not compatible with the Windows 10 version you are running. Since that’s the case, you need to update Windows 10 to fix the problem. Updating your Windows 10 computer is the only solution you can try to fix this problem. Thus, it is advised that you check for Windows Updates even if you are now using the latest version of Windows 10. And since the issue is caused by an incompatible operating system version, once you install the exact version of Windows 10 required by the .Net Framework, the problem will be fixed. Simply follow the steps given below to do so.

• Step 1: Tap the Win + R keys to open the Run dialog box.
• Step 2: After that, type in “winver” in the field and tap Enter.
• Step 3: Next, your Windows 10 version should be given in the new window that appears. Take note that the number after the Version which is in the second line is your version number of Windows 10. And that the number must be 1507 or 1709. The first two digits in these numbers are the year while the second two represent the month when the update was released. So if you are running a 1709 version, this means that the Windows 10 version you are using was released in September 2017.
• Step 4: The next thing you have to do is to make sure that you have the Windows 10 version that’s compatible with the .Net Framework. To verify, you need to click here and click on the System Requirements.

After opening the link, take a look at the Supported Operating System section where it says, “Windows 10 Anniversary Update” and “Windows 10 Creators Update”. Since there are users who are not familiar with the version numbers related to both the Anniversary and Creators updates, refer to the list given below.

• November Update (1511)
• Anniversary Update (14393)
• Creators Update (1703)
• Fall Creators Update (1709)
• Spring Creators Update (1803)

As you can see, the Creators Update has version 1703 while the Anniversary Update has version number 14393 so if you are using a version lower than the 14393 version then it’s no wonder you aren’t able to install the .Net Framework 4.7 on your Windows 10 PC. Now all that’s left to do is to update your Windows 10 version and make sure that you will be updating it to the latest version available and then try installing the .Net Framework again.

As you know, the Graphics Card in a computer is one of the important components in an operating system as they are responsible for rendering various objects in your computer. However, there are cases when the performance of this rendering can degrade and your computer can trigger a VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen of Death error instead. The VIDEO_SCHEDULER_INTERNAL_ERROR bug check has a value of 0x00000119 which means that the video scheduler has detected a fatal violation in your computer. Before you troubleshoot the problem, you might want to perform System Restore first as it might help you fix the Stop error. To perform System Restore, refer to these steps:

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the Stop error is fixed or not.

If the VIDEO_SCHEDULER_INTERNAL_ERROR BSOD error is still not fixed after System Restore, then follow the given options below to further troubleshoot the problem.

Option 1 – Try to manually check the Graphics Card hardware

You might also want to check the physical status of your Graphics card and you can do this by disconnecting the Graphics card or any other external device connected to your computer. Once you’ve removed the external device, check it for any damages. If there’s none, connect it back to your computer and check if the VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen error is fixed or not.

Option 2 – Try removing hardware or drivers that you’ve installed recently

If you have recently installed some hardware or drivers, you might want to disable or remove them since external devices are proven to be one of the factors that trigger Blue Screen errors like VIDEO_SCHEDULER_INTERNAL_ERROR. All you have to do is physically disconnect any external devices that are connected to your computer and then check if it fixes the BSOD error or not.

Option 3 – Try to rollback, update, or disable the Graphics card drivers

Since the VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen error has something to do with Graphics card drivers, you can either roll back, update or disable them depending on your preference in order to resolve the error.

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.

• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 4 – Uninstall any faulty drivers

You can also uninstall any faulty drivers via Device Manager. How? Refer to these steps:

• Tap the Win + R keys to launch the Run dialog box.
• Then type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• From there, look for any faulty drivers. You can identify them easily as they will be marked with a yellow exclamation point. And then check which entries would not affect the normal functioning of your PC.
• Now click on the entries of every faulty driver and click on the Uninstall option.
• Once you’ve uninstalled them, restart your computer to allow your computer to reinstall the faulty drivers you’ve just removed.

Option 5 – Run System File Checker at boot time

• Once you get to the Welcome Screen part, click on Next.
• Afterward, click on the Repair your computer option located on the bottom-left part of the window.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• After opening Command Prompt, type the “sfc /scannow” command and hit Enter to run the System File Checker scan.
• Wait until the process is completed and type “exit” to close Command Prompt and then restart your computer to successfully apply the changes made.

Option 6 – Try to run the Blue Screen Troubleshooter

As you know, the Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like the VIDEO_SCHEDULER_INTERNAL_ERROR error. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Changing Taskbar location in your Windows 10 is an easy task but lately, Microsoft has removed the option to just drag it to one side of the screen and place it there, now in order to change location we need to do a little more work but do not worry it is not difficult at all. Right-click on the taskbar to open its properties menu in the menu, on the bottom choose taskbar settings. Once the settings dialog opens, on the right side locate the taskbar location on screen. Click on the dropdown menu and choose the desired location for the taskbar.
