Removing Search.schooldozer.com hijacker

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.

There are times when you try to open a file, an executable file for instance, but were unable to do so since you encounter an error in an Open File – Security Warning dialog box that says, “This publisher has been blocked from running software on your machine, You must unblock this publisher to run this software”. This kind of error is most likely thrown by your operating system because it considers the file to be unsafe and could potentially harm your computer. However, if you’re certain that the file is harmless, read on as this post will walk you through fixing the error so you can open the file without getting an error. There are various options you can check out to fix the error. You may run the program using Command Prompt or unblock it using File Properties. You could also try turning off SmartScreen or use the unblock file command in Windows PowerShell.

Option 1 – Try running the program via Command Prompt

  • Tap the Win + R keys to open the Run dialog box and type “cmd” in the field and hit Enter to open Command Prompt.
  • Next, tap the Shift key and right-click on the program or the executable file, and then select the “Copy as path” option.
  • After that, paste this path in the Command Prompt window and tap Enter to open the program.

Option 2 – Try to unblock the file using File Properties

  • Right-click on the file you were trying to open and select Properties.
  • Next, click the Unblock button and then click on the Apply and OK buttons.
  • You should now be able to open or access the file without getting the error.

Option 3 – Turn off SmartScreen

The next thing you can do is to turn off SmartScreen temporarily. All you have to do is open the Windows Defender Security Center and from there, go to the App & browser control section. After that, click on the radio button for Off under Check apps and files. Once you’re done, try opening the file again. Don’t forget to enable the SmartScreen back on.

Option 4 – Try to use the Unblock-File command in PowerShell

You might also want to utilize the Unblock-File command in Windows PowerShell as it will unblock the file so you can open it. To execute this command, follow these steps:
  • Tap the Win + X keys and then click on Windows PowerShell.
  • After opening PowerShell, type or copy and paste this command and tap Enter to execute it: Get-ChildItem -Path 'C:Users<username>Downloads' | Unblock-File
  • The command you entered will unblock all the files in the Downloads folder, assuming that’s where the file you were trying to open is stored. If it’s not, then replace the path with the path where the file is located. Take note to also replace “<username>” with your Username.
  • Now check if the file has been unblocked by accessing or opening it.

Valorant will enforce Windows 11 TPM 2.0
Valorant ingameBad or good news, depending on your view comes from RIOT for their game Valorant. It seems that Riot has decided to enforce Windows 11 TPM 2.0 feature into Valorant running on Windows 11 and there is a rumor that it will be de facto standard and that it will move to Valorant in general no matter on which system it runs. Furthermore, there is a rumor circling around that other developers are also talking about implementing TPM 2.0 requirements so they can harvest advanced security features of Windows 11 in order to prevent hacks and other cheats in their games. This is an interesting point to stand on, on one side, sure, advanced features that will prevent cheating and hacking is a great thing. On other hand denying access to many computers that do not support TPM 2.0 and removing them from the game can be a permanent loss of customers and therefore loss of money. It is a risk to be sure and I am not really sure that alienating gamers is a good choice for long-term income, especially when you will be able to install Windows 11 on an unsupported PC as stated by Microsoft. We will all see how this Riot decision will reflect on their business, as not a big Valorant player myself I am not impacted too much with this decision, but it will be interesting to see if others will indeed go with this trend or they will decide to wait a while until much more PC’s are upgraded.

USB keep disconnecting and reconnecting
If your USB keeps disconnecting and reconnecting after you connect your USB device on its own randomly, then the problem might have something to do with a hardware or driver issue. The first thing you have to do in such a case is to make sure that the device is working on another computer. This will help you isolate the problem and if it turns out that it works, then the problem lies in your computer and not your USB device. To fix this connection problem between your USB device and Windows 10 computer, you can use the options given below as a reference.

Option 1 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:
  • First, click the Start button and type “device manager”.
  • Then click on the “Device Manager” from the search results to open it.
  • From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 2 – Try to change the USB port

You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it.

Option 3 – Try to turn off the Power Saving option

You could also try to turn off the Power Saving option to resolve the problem. All you have to do is switch to Power Management after you select the Properties of the USB device and from there, uncheck the “Allow the computer to turn off the device to save power” option. On the other hand, if you are using a laptop and did not use the USB device for a long time, then it could be powered off. This will ensure that the system does not turn off the USB device.

Option 4 – Try to reinstall the latest Universal Serial Bus controller drivers in Compatibility Mode

If you were unable to install the Universal Serial Bus controller drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:
  • You need to download the driver and place it on your desktop.
  • After that, right-click on it and select Properties.
  • Next, switch to the Compatibility tab where you should see two options:
    • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
    • Manually choose the version of Windows it was correctly working.
  • Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.
Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 5 – Run the Hardware and Devices Troubleshooters

  • The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
  • After opening Settings, look for the Update and Security option and select it.
  • From there, go to the Troubleshoot option located on the left-hand side of the list.
  • Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
  • After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Now, a new player enters the AI video battlefield, its name is GOOGLE!

google ai

The Google research project Imagen Video is also text to video generator similar to Meta's Make a Video with one little difference. unlike Meta's offering which includes only sign-up, Google is withholding access for now under the veil of safeguarding issues.

Google has been in the Ai space before with their Imagen, a DALL-E style generator capable of photorealistic picture generation based on text prompts. The new Google tool works in a similar way but with better functions. Ai can generate a diverse range of high-fidelity videos across different aesthetic styles and with a deep understanding of 3D models thus creating high-definition, 24-frames-per-second videos.

"With the help of progressive distillation, Imagen Video can generate high-quality videos using just eight diffusion steps per sub-model. This speeds up video generation time substantially, by a factor of ~18x,”

Jonathan Ho, author of the research paper

Despite filtering for “undesirable content”, the team admits “there is a risk that Imagen has encoded harmful stereotypes and representations”. So, until the AI - and its users - can be trusted, Google refuses to release Imagen Video without additional safeguards in place.
