About Browser Hijackers

Browser hijack is a very common type of online fraud where your internet browser settings are modified to allow it to carry out things you don’t intend. They’re created to disrupt browser functions for several purposes. It redirects you to the sponsored sites and inserts ads on the web browser which helps its developer generate earnings. Nevertheless, it’s not that naive. Your web safety is jeopardized and it is also extremely irritating. They don’t just ruin your web browsers, but browser hijackers could also modify the computer registry, making your PC vulnerable to other attacks.

How one can know if your web browser is hijacked

Signs that an internet browser is a hi-jacked include: the browser’s home-page is modified; you find yourself regularly directed to a different site than the one you meant; the default search engine is changed; unwanted new toolbars are added to your web browser; never-ending pop-up ads show up and/or your browser pop-up blocker is disabled; your web browser starts running sluggishly or displays frequent glitches; You simply can’t access specific sites, particularly anti-virus sites.

How they infect PCs

A browser hijacker can be installed on your computer when you check out an infected website, click an e-mail attachment, or download something from a file-sharing website. They are usually included with toolbars, BHO, add-ons, plugins, or browser extensions. A browser hijacker could also be installed as a part of freeware, shareware, demoware, and fake programs. A good example of a notorious browser hijacker is the most recent Chinese malware known as “Fireball”, which has attacked 250 million computer systems worldwide. It acts as a hijacker but can be turned into a fully functioning malware downloader afterward. Browser hijackers could affect the user’s browsing experience greatly, keep track of the websites visited by users and steal private information, cause difficulty in connecting to the internet, and ultimately create stability issues, making software programs and systems freeze.

How to repair a browser hijack

Bad_Pool_Header Error - What is it?

Bad_Pool_Header is one of the types of BSOD (Blue Screen of Death) error codes. This error triggers a problem with Windows memory allocation. When this error message occurs, the screen turns blue and locks the user out of the application running on the system. The computer shuts down or restarts.

Solution

Error Causes

There is no one particular cause for the occurrence of the Bad_Pool_Header error code. It may appear on your system due to multiple reasons such as:

• Device driver issues
• Cluttered disk
• Disk writing issues
• Faulty memory hardware

Driver issues and disk writing issues occur when your try to update new driver versions. During this process, users often forget to remove the files of the uninstalled version from the registry. And due to the presence of the uninstalled driver files in the registry updating and disk writing becomes an uphill task which leads to the Bad_Pool_Header display on the computer screen. The main database of your system is the registry so you need to keep it clean to avoid disk cluttering. The hard disk clutters because the registry saves all the activities that you perform in your system. It saves junk files, internet history, invalid entries, and other unnecessary files. This occupies a lot of your disk space thus resulting in disk cluttering and faulty memory hardware issues triggering the Bad_Pool_Header. Ignoring the Bad_Pool_Header error is not wise. It is advisable to repair the Bad_Pool_Header right away as it can lead to serious threats like system failure and data loss.

The first major update for Windows 11, 22000.65 has brought some bug fixes and some new features. The previous update was just a bunch of small fixes but this time Microsoft has brought much more with this one.

Bug and security fixes:

• Patch for the PrintNightmare vulnerability.
• Taskbar icons not displaying after you rotate the screen back and forth.
• Date and time not following format settings.
• Contrast issues with File Explorer title bar
• Search dropping the first keystroke when you press the Windows key and type
• Blurry windows in ALT + Tab

Besides bug and security fixed newest update has also brought us some functional changes:

• The start menu can no longer be moved from center
• A search box appears at the top of the Start menu.
• Taskbar appears on secondary monitors.
• The refresh option appears on the jump list when you right-click the desktop. It was on the "Show more options" list before.
• New look for certain dialog boxes such as "battery low" or "display change"
• New snap layouts for portrait mode screens.
• Option to troubleshoot sound problems when you right-click the volume icon.
• Power mode settings on Power & battery settings menu.
• Right-clicking .ps1 files offers a "Run with PowerShell" option.
• New GIFs in the emoji panel in China

Honestly, I really like a search box on top of the start menu but really dislike the option to move it to left, I am sure that there are a lot of users who would feel more like at home if they could still move and set Windows to function and work how they want. It is very strange to me that Windows 10 was made to be so user-focused and been able to be user specific and Windows 1 takes most of these things away. I am not sure why Microsoft is going this way but I cannot really see how moving the taskbar on left is a programming issue or why it is wrong for example.

If you are using UEFI and you encountered an error message that says, “Selected boot image did not authenticate”, then read on as this post will show you what to do it fix it. This kind of error indicates that UEFI is having an issue in figuring out if the boot image has tampered with. UEFI offers Secure Boot and if the boot image seems to be invalid, you won’t be allowed to boot into your computer. Aside from that, it could be that you may be using endpoint encryption and the software can’t validate the certificate. To fix the “Selected boot image did not authenticate” error in UEFI, you need to first check if the error has given any reference to any software that you might have for encryption. If it has, then you need to disable the Encryption tool to resolve the problem. In addition, you could also try to disable Secure Boot or perform Startup Repair in case the disabling Encryption tool didn’t work. For more details, make sure to use each one of the options provided below as a reference.

Option 1 – Try to disable the Encryption tool

The first thing you can do to fix the “Selected boot image did not authenticate” error is to disable the Encryption tool. Many users reported that some encryption tools like the ESET Endpoint Encryption won’t let them boot into the computer if the system manufacturer does not include the correct certifications as a part of the UEFI BIOS. And since there is no way to bypass this, you have to disable Secure Boot in order for you to boot into your computer.

Option 2 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the error. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 3 – Try to run the Automatic Repair Utility

If disabling Secure Boot did not fix the problem, you might also want to run the Automatic Repair utility in fixing the error. To do so, follow the steps below.

• You can start by booting into the Advanced Recovery Mode.
• After that, select Troubleshoot > Startup Repair.
• Next, follow the on-screen instructions that appear on the screen and finish the Automatic Repair process.
• Now check if the block is gone once the reboot is completed.

In the latest Windows 11 fiasco, it is reported that the operating system is slowing down some SSD drives. Good thing is that it does not affect all of SSD on the market but the ones which it is affecting can see even a 45% of speed drop. Microsoft has not published a solution to this issue, but users point out two potential problems. The first is a security mechanism based on disk virtualization, which is supposed to slow down the performance of SSDs. The second, in turn, is related to the place of installation of Windows 11 – users indicate that if the performance test is performed on a medium with no files associated with the system, its performance results are similar to the parameters given by the manufacturer. Transfer speeds were to be slightly improved with the latest Windows 11 update 22000.348. However, users are still waiting for a solution to the problem that significantly reduces the efficiency of SSD media.

More information

The details described leading to speculation that the problem could be related to drivers that Microsoft is providing. On further tests, all Nvme drives that use the Microsoft driver have this problem, but Intel 905P, which has its own driver provided by Intel, is working at full power,”.

The world today is still sadly under pandemic and by the looks of it, COVID-19 is here to stay, well at least for some time in the near future. Razer seems to think so as well since their upcoming gear is not really what you would expect. Enter Hazel, a new and upcoming Razer smart mask.

Protection

Hazel mask has a high bacterial surgical N95 filter with fluid resistance that will protect you against large droplets and splashes. A detachable active ventilator regulates airflow and is capable of filtering around 95% of airborne particles. Mask comes with a special charging case that has an auto sterilization UV light that will kill bacteria and viruses inside the case interior while it charges. When the mask is recharging it will change color from red to green visually showing the level of the current charge. Mask of course has easy to replace filters inside ventilators and Razer is standing by that fully charged mask will last enough for full-day use. An active ventilation system brings cool air while releasing breathing heat at the same time drastically reducing CO2 inside the mask that could produce dizziness and headache. Silicon guard is on its edge gluing to around your face in order to prevent exterior air sneaking inside the mask and positioning it firmly so it does not rest on your lips in order for easier and clearer communication.

Hazel personalization and technical features

Hazel has a clear and transparent design making it better for social interaction since other people will be able to see your lips and smiles thus making it more natural. A low light mode that turns on automatically when it is dark outside is also aimed for easier communication. Speaking of communication, the mask comes with voice Amp technology that has a built-in mic and amplifier thus making your voice lines clear so you are not muffled when wearing the mask itself. Your friends and other people will be able to hear you like you are not wearing a mask at all. Thicker air loops apply less pressure on ears and can be adjusted for a more secure fit, while the mask itself can be custom-made to fit your face shape. And of course Hazel comes with 16.8 million colors and a suite of effects with Razer Chroma RBG

The Google Chrome browser checks the SSL Security Certificate of the website that you are trying to open. However, if Chrome is not able to check the certificate then you might encounter an error related to the SSL Certificates which you might face when browsing the web. This particular error is the ERR BAD SSL CLIENT AUTH CERT error which is caused by many factors such as the computer’s Time, Cached Data is corrupt, Date is out of sync, as well as third party software installed in your computer is the one that’s blocking the site and many more. The ERR_BAD_SSL_CLIENT_AUTH_CERT error might also be coming from the website’s end. It could be that the server is rejecting the certificate the client website is sending. The certificate might have already expired or the server may not trust its issuer – whichever the case may be, here are some options you can check out to fix the error.

Option 1 – Sync Date and Time

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the ERR_BAD_SSL_CLIENT_AUTH_CERT error. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.

• Right-click on the Taskbar and click on the Adjust Date and Time option.
• Next, click on the Sync Now button to synchronize the Date and Time with the Microsoft Servers.
• Now make sure that the Time Zone that’s set on the same page is correct.

Option 2 – Try clearing the browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BAD_SSL_CLIENT_AUTH_CERT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.

Option 3 – Try to check and fix any possible conflicts with third-party programs

Third-party programs like internet protection software could be interrupting the connection and causing the error. For some unknown reason, your antivirus program or firewall might be detecting the webpage you are trying to open as malicious or with less credibility which is why it is blocking the browser from opening the website. To fix that, if you have third-party programs installed like VPN, security software, or any add-on, or firewall, you can disable them temporarily and see if it fixes the problem and you’re able to pull up the website. After a while, you have to enable them back and configure their settings so that the website won’t get blocked again.

Option 4 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR_BAD_SSL_CLIENT_AUTH_CERT error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
• Restart the browser.

On the other hand, if you were using Firefox when you go the error, here’s what you have to do.

• Open Firefox and in the address bar, type “about:config” and hit Enter.
• If a warning appears, just click on the “I accept the risk!” button to proceed.
• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

Option 5 – Try to update Google Chrome

You might also want to try updating your browser to its latest version and have it installed in your computer. After you install the update, check if you can now open the website you were trying to open earlier.

Option 6 – Get rid of any conflicting browser extensions

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.
• To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

Note: If removing the browser extensions or toolbars didn’t work, you can also try to reset your Google Chrome browser.

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.

Error code 0Xc004F074 - What is it?

Did you previously use Windows 7 or 8 but decided to run with the latest Windows 0S, Windows 10? An early error message encountered was activation error code 0Xc004F074. Error code 0Xc004F074 is manifested when the user fails to activate Windows directly after the installation of Windows 10. This occurs if the previous operating system on your computer was Key Management Service (KMS) activated.

The KMT provides a more seamless operation when users are activating volume license editions of Microsoft Windows and Office. This process tends to be clear to end-users of the system.

Symptoms of error code 0Xc004F074 include:

• Windows is unable to reach your company’s activation service.
• The Key Management Service is unavailable.

Solution

Error Causes

Various factors might incite error code 0Xc004F074. A primary cause is a discrepancy or difference between the KMS client and the KMS host machine. The host computer could possibly be operating a Windows Server 2003 or Windows Server 2008, while the client runs on OS Windows 7 or Windows Server 2008 R2. To supplement, the computer’s time might be a contributing factor. The time on the host machine and client might show a difference (Usually the host time exceeds 4 hours).

Further Information and Manual Repair

To rectify error code 0Xc004F074, users are advised to try various methods. These methods include:

1. Method 1: Update Your KMS Host 9 (Windows Server 2003)

Are you running later versions of Windows Server? Use an update that fixes or installs KMS on your computer. The update is available on Microsoft’s website. Keep clearly in mind that the update is only for Windows Server 2013 Service Pack 1 and later versions of Windows Server 2003.

2. Method 2: Update Your KMS Host 9 (Windows Server 2008)

This step is similar to the aforementioned. However, it applies to Windows Vista and Windows Server 2008. This ensures the service is extended to Windows 7 and Windows Server 2008 R2.

3. Method 3: Update the Time

It was previously mentioned that the time reflected on the KMS host and client might cause error code 0Xc004F074 to manifest. A simple fix to adhere to is to always ensure that the time between both is updated. To Resync the time on the client, execute the following command.

w32tm /resync

4. Method 4: Uninstall the Existing KMS

For this method to be successfully deployed, you’ll need to have in your possession an activation key or KMSpico Key. As you cannot apply the new key with the existing one, remove or uninstall the initial key. To perform this step, open the command prompt. This should be done while the computer is in admin mode. Then, run the command

(slmgr.vbs /dlv)

It should be executed without the brackets and before you have removed the existing key.

After executing the command, you’ll encounter the description:

Windows(R) Operating System, VOLUME_KMS_WS12_R2 channel

Move along with the process by applying the slmgr.vbs /upk to uninstall the existing KMS key.

After the old key is uninstalled, you’re ready to apply the following:

slmgr.vbs /ipk <NewKMSProductKey>

To check if things are in place and complete the process, follow the steps below: PC Settings >Update and Security > Activation

5. Method 5: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc. Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.

Option 1 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
  • exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:/Windows/System32
  • x64: This PC > C:/Windows/SysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 3 – Perform a System File Checker scan

The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Try reverting back to the previous build of Windows

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.

There are instances when the Windows 10 installation needs interaction before it reaches the file process. And so if you suddenly encounter the Windows Update Installation Failure 0x80240020 error under the Windows Update History, then you need to get it fixed. When you encounter this kind of Windows Update Error, you will see an error message that says, “The operation did not complete because there is no logged-on interactive user”. This error also indicates the “WU_E_NO_INTERACTIVE_USER” code. To resolve this issue, in this post we’ll walk you through a couple of steps but before you get started, know that you don’t have to run any troubleshooter or delete any file just to fix this error since all you have to do is enable one option that can automatically login with your account and complete the installation for you. With that said, just make sure to only try running Windows Update once you’re told to do so. There are two ways you can enable the option that could resolve the Windows Update Installation Failure 0x80240020 error. One is via Settings while the second one is via Registry Editor.

Option 1 – via Settings

Step 1: Go to Settings > Accounts > Sign-in Options. Step 2: From there, toggle on the “Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart” option. Step 3: After that, it will make sure that the interaction part is removed from the Windows Update process. Note: If your device is joined in a domain or if some work or email policies are applied to your device by your company or organization, then you wouldn’t be able to see this option in Settings and that’s where the Registry Editor comes in. Just make sure that you’re logged in as an administrator and that you create a System Restore Point first since registry hacks are sensitive and could highly impact how your computer behaves or functions. Once you have that covered, follow the steps below.

Option 2 – via Registry Editor

Step 1: In the Start search, type “Regedit” and hit Enter to open the Registry Editor. Step 2: Navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade

Note: If the above-given registry key does not exist, you can simply create it. All you have to do is right-click on the WindowsUpdate key and then select the New Key option and type “OSUpgrade” as its name. Afterward, create a new DWORD (32-bit) Value and name it “AllowOSUpgrade” and set its value to 0x00000001. Step 3: Restart your computer and check if the error is now fixed. And then try to update your Windows 10 computer again and while you’re at it, make sure that you’re around your computer to interact with the prompts needed to complete the installation process.
