About Browser Hijackers

Browser hijackers (also known as hijackware) are a type of malware that changes internet browser configurations without the user’s knowledge or approval. These kinds of hijacks happen to be rising at an astonishing rate across the world, and they can be truly nefarious and sometimes harmful too. Nearly all browser hijackers are created for marketing or advertising purposes. These are generally used to force visitors to a specific website, manipulating web traffic to generate ad revenue. Even though it might appear naive, these tools are designed by vicious individuals who always attempt to take full advantage of you, so that they could make money from your naive and distraction. Browser hijackers can also allow other vicious programs without your knowledge to further damage your PC.

Signs of browser hijacker malware

Below are some signs and symptoms that indicate your internet browser has been hijacked: your browser’s home page has been reset to some mysterious site; you find redirected to websites you never intended to visit; the default web browser settings are changed and/or your default search engine is altered; you find multiple toolbars on the browser; you’ll find random pop-ups start showing regularly; your internet browser starts running sluggishly or displays frequent glitches; you can’t visit certain sites such as homepages of antivirus software.

How it infects the computer

Browser hijackers can get into a computer by some means or other, including via file sharing, downloads, and e-mail as well. They may also be deployed via the installation of an internet browser toolbar, add-on, or extension. A browser hijacker could also be installed as a part of freeware, shareware, demoware, and fake programs. An example of some infamous browser hijackers includes Babylon, Anyprotect, Conduit, SweetPage, DefaultTab, Delta Search, and RocketTab, however, the names are continually changing. The presence of any browser hijacker malware on your system can substantially diminish the web browsing experience, record your online activities that lead to serious privacy concerns, develop system stability issues and finally cause your PC to slow down or to a nearly unusable condition.

In cases of suspicious versions of browser plugins, you can actually get rid of it via your browser’s extension manager. You will probably also want to reset your internet browser.

If you’ve tried resetting your Windows 10 computer using the Reset This PC option in order to restore your computer’s factory settings and the process suddenly fails for some reason and you got an error message instead stating, “There was a problem resetting your PC, No changes were made on your Windows 10 computer”, then this post might help you resolve the problem. Carefully follow each one of the options given below to resolve the “There was a problem resetting your PC error on Windows 10.

Option 1 – Try renaming the System and Software hive

• If you’re still able to boot to the desktop of your Windows 10 PC, open an elevated Command Prompt from the WinX menu.
• Now use the CD command and change the directory to Windows\System32\config folder. Simply type in the following command and hit Enter:

cd %windir%system32config

• After that, you have to rename the System and Software registry hives to “System.001” and “Software.001”, respectively. To do that, just type each one of the following commands and hit Enter after you type each of them.
  • ren system system.001
  • ren software software.001

On the other hand, if your Windows 10 PC isn’t able to boot to the desktop, you can just access Command Prompt from the Advanced Startup options or you can also boot into Sage Mode and open Command Prompt from there and then run the given commands above. Note: If you only want to use the Refresh your PC option, you must only rename System hive and not Software hive. On the other hand, if the Software hive is really corrupted, you might not be able to use the Refresh your PC option in such a case. Thus, you really need to rename the Software hive as well. Once you’ve renamed the Software hive, you won’t be able to use the Refresh your PC option but only the Reset your PC option.

• Type “exit” to close the Command Prompt and then restart your PC and try resetting your PC again.

Option 2 – Try to disable and re-enable the Windows Recovery Environment

If the first option didn’t help, you can try disabling the Windows Recovery Environment and then enable it back again. To configure a Windows Recovery Environment or Windows RE boot image and recovery options, you have to use the REAgentC.exe tool.

• Tap the Win + S key and type “REAgentC.exe” to open the REAgentC.exe tool.
• After that, type the following command and hit Enter to disable the Windows RE:

reagentc /disable

• After disabling the Windows RE, you need to enable it back by typing the following command:

reagentc /enable

Option 3 – Try to boot the USB recovery drive

If the two previous options failed, you need to try another workaround which is to boot to the USB recovery drive > Troubleshoot > Recover from a drive. From there, follow the on-screen instructions and you should be good to go.

The holiday season is almost upon us and buying gifts for loved ones can sometimes present some headaches, especially if that loved one is a Gamer or PC enthusiast. We have all been there and how almost every household today has a console or PC struggles are infecting more and more people. But do not despair, we have made a nice list of potential gifts for you. The list contains some nice essential and good things but we gave our best not to break the bank so you will not find any large screens or 300$ keyboards here. Of course, you can always get expensive gifts and if you have money for it do it, it is just we want to have affordable stuff here.

A Steam gift card

For gamers, a good game is a great gift but most of the time when we are buying a game we can miss what the person wants. That is why a Steam gift card is a great gift for gamers. He can use it and buy whatever he or she wants for its value.

Xbox Game pass

This is another for those Gamers type. Xbox game pass is a great gift even if you do not own Xbox since all games will work on PC as well. Xbox Game Pass Ultimate includes the PC version, which will unlock somewhere between 300 and 350 games automatically. It’s a subscription service, so your PC gamer will have to keep up with it. The monthly price is worth it, though.

Pack of cable ties

Almost every PC user has tons of cables lying around, and most of the time they are not really tidy. Cable ties come to the rescue!!! Let us be honest, no one likes cables that are scattered all over the place, even the computer users so if they do not have this essential piece of equipment, we are sure they will like it.

Compressed air duster

Dust is enemy no.1 for computer users, it gets into the keyboard, into small spaces, etc. It is very difficult to get it out so an air duster for compressed air is a great cleaning gift for any kind of computer enthusiast. You can get it with a can of compressed air as well so everything is ready for cleaning.

New Headset

A headset is always a great gift. Over time earbuds can deteriorate and get damaged simply just by using them and when enough time passes even cables can start losing contact and overall sound quality may drop. Usually, computer users change headsets like keyboards so if your loved one has some old headsets showing their age, a new one is a perfect present.

New SSD drive

More hard disk space is always a welcome sight for any PC user and new SSD drives fueled with new technology are faster than ones of the same size in past years making them a perfect gift.

Large mouse pad

A good mouse pad can mean a lot to a gamer. Over time mouse pad deteriorates simply with its use so a new and fancy large pad is a great gift for any user. If you want a great gift, make it with RGB light.

Despite popular belief, there are a lot of users running Linux OS. Linux offers great security and working environment and 96.3% of the world's top 1 million servers run on Linux. 90% of all cloud infrastructure operates on Linux and practically all the best cloud hosts use it. But gaming on Linux is limited, enter Steam proton a Valve’s gaming solution.

What is Steam proton?

Proton is a WINE fork with some extra capabilities, to play games and run applications not native and not made to run natively under Linux OS. It is supposed to bridge the Gaming issues for PC users and let them more freedom in choosing an operating system to game on.

Find out if your game supports Proton

Although there are a lot of titles that nowadays run natively on Linux some will still need proton in order to run at all and sadly some of them will not be able to run on Linux even via proton but seeing how Valve is busy and it is trying to push its ideas and technology slowly this gap is closing. In order to see how the game you want to play performs and behaves on Linux and proton environment visit https://www.protondb.com/ and find out. As soon as the site loads you will be greeted with statistics and a search option to find out the status of the desired game with one of the given statuses: Borked, Bronze, Silver, Gold, Platinum, and Native. As you probably guessed native means that the game will work on Linux out of the box and borked will probably not work at all. Platinum and gold status means that game will run on proton without any input or tweaks from the user while silver and bronze means that it will work but might need some tweaks in order to make it work.

How to get Steam proton?

In order to run games under proton inside Linux, you will need firstly a Steam client which luckily works naturally on Linux. Unlocking/activating Steam Proton on your Linux-based system is easy. Just head over to Steam > Settings > Steam Play and toggle the option “Enable Steam Play for Supported Titles”. Valve has tested and fixed some Steam titles and you will now be able to play those titles. However, if you wish to go even further beyond, and play titles that even Valve has not tested, toggle the option “Enable Steam Play for all titles”.

Conclusion

Even we are not there yet, native gaming on Linux is gaining a foothold each day. Will Steam’s OS with proton technology be one that will turn the tide from Windows or some other tech we cannot tell but one thing is for sure, more choices mean better products so I am hopeful for a bright future.

In case you don’t know, the Title bar comes with the Maximize, Minimize, as well as the Close button. However, there are instances when you might notice that the Title bar, Maximize, Minimize and Close buttons are missing in the File Explorer. This kind of problem might be due to some glitch in the computer, or it could also be caused by some built-in tool or an installed program in your computer. Moreover, there are also other factors that you have to consider such as corruption in the system files as well as errors in the user profile which is generated on a domain network, and so on. There are several suggestions you can check out to fix the problem. You can try to boot your computer in a Clean Boot State to see if a third-party program is the root cause of the problem. You can also try to run built-in tools like System File Checker and the DISM tool. You could also get the video buffer emptied, reset or reinstall the program, or recreate the User Profile.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as 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.)
• You need to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it.

Option 2 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

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

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.

• Restart your computer and see if the System32 folder still pops up at startup or not.

Option 3 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Windows Upgrade problem. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try to empty the Vide buffer

These kinds of problems could also be due to bad data in the Video Buffer. Thus, you can try to empty the Video buffer to resolve the problem. All you have to do is tap the Shift + Ctrl + Win key + B keys on your keyboard. After that, leave your computer idle for about 10 seconds until you notice it blink once. Now you try using your computer as usual and see if the glitch is now fixed or not.

Option 5 – Try to reset or reinstall the program

Another thing you can do to fix the issue is to reset or reinstall the program where you encounter the problem. Chances are, you are running the application in the Full-screen mode but you can exit it by simply tapping the Esc or F11 key. However, if nothing changed, then consider resetting or reinstalling the program. Just go to the Windows 10 Settings app and navigate to Apps > Apps & Features. From there, look for the entry of the application you’re having problems with and select it and then click on the Advanced options. After that, click on the Reset button under the Reset section.

Option 6 – Try recreating the User Profile

You might also want to try recreating the User Profile on your computer since some errors in the creation of a User Profile can result in problems like this one. Thus, you have to try deleting the User Profile and then recreate it.

Error Code 0x8007267C – What is it?

Error code 0x8007267C is specific to Windows 10. This error is triggered when no DNS server is currently configured in your network settings during the Activation process. If you are fairly confident in your ability to address command-line tools and networking issues, you can follow the steps below to try to remedy the error code on your own. If not, you may need to contact a qualified technician in order to resolve the error successfully.

Solution

Error Causes

The cause of Error Code 0X8007267C within the Window 10 system is fairly straightforward. Windows Activation requires a valid DNS server to be configured in order to complete the Activation process; if one is not available or properly configured, then you may see this error code and Activation will fail.

Further Information and Manual Repair

The following methods may help you to resolve this error, but you’ll need to have some familiarity with command-line tools to complete the steps successfully. If these methods do not work or if you are uncomfortable in using the command prompt, you may need to consult a technician to fully resolve this particular error code on the Windows 10 system.

Method 1: Register a DNS server within your network properties and test the connection.

In order to resolve this error code, client connectivity to a DNS server must first be established. The following steps may help you to determine the root problem with your connectivity status:

1. Open a command prompt, after which you'll run IPCONFIG /all
2. Verify the following values: The IP address that has been assigned, the DNS server, the subnet mask, and the default gateway. Compare each to ensure that all are set with the values that correspond to your specific environment
3. Check for basic IP connectivity to the DNS server using the PING command. In using the PING command, utilize the address of the DNS server found in Step 1

ping <DNS Server IP address>

If basic connectivity to the DNS server in question is failing, then you will need to resolve that issue before going further in the process.

After troubleshooting the above basic connectivity issues to the DNS server, you can reattempt Windows Activation by using the command below from within an Elevated Command selection:

cscript windowssystem32slmgr.vbs -ato

If the steps above did not work for you, you may want to try the steps found in method 2.

Method 2: Use phone-based authentication with a MAK (multiple activation key).

If a DNS server is not connected to your network, you can use an alternative method to complete the Windows Activation process. Bypass Method 1 by using a MAK product key instead to activate the volume license installation. Certain MAK product key providers have a variation on the specific key numbers that you will need to use. If you are using TechNet media or MSDN media, you will have to change the product key listed to the product key provided. The product keys provided by either TechNet media or MSDN media for Windows Server 2008 or for Windows Vista Enterprise will be the MAK product key that you will enter in a later step.

Like the previous method, you will need to have some familiarity or confidence in your ability to operate Command Line tools before proceeding. Once you have found your MAK product key, you’ll need to open a command prompt and use the following command to change the product key to match the MAK product key, which should look something like the example below:

            slmgr –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

After completing the product key change, use the following command to initiate the phone activation wizard, thereby completing the activation of the system:

            slui 04

The activation wizard should be able to walk you through the remainder of the process in a step-by-step manner. In addition to appearing as an error code in Windows 10, this particular error may apply to multiple versions of Windows, including:

• Windows 7 Enterprise
• Windows 7 Enterprise E
• Windows 7 Enterprise N
• Windows 7 Professional
• Windows 7 Professional E
• Windows 7 Professional N

Steps to address the error code may be different in any of these other versions of Windows. If you have difficulty in resolving the error effectively, seek professional technical help.

The latest steam beta update has introduced code that will prevent downloading and installing previous game versions via the steam client.

It is important to point that update is still in beta client only but users have already started to voice their opinions asking Valve not to place it live. In the end, it will all depend on Valve’s decision will they listen to their customers or decide to push updates on live service.

Error Code 48 – What is it?

Error Code 48 is a device driver error code that users can encounter on any Windows 2000 operating system and later versions.

It occurs when the connected peripheral device cannot be run as the Windows operating system’s driver required to install the programs for peripheral devices has either been corrupted or is incompatible with the system.

It prompts the user with the following message on the screen:

The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)

Solution

Error Causes

Like most other Windows error codes, error code 48 is triggered by the following factors.

• Corrupted system registry files
• Presence of viruses in the device
• The device driver is out-of-date

If this error code is not rectified, it could give birth to other driver device errors such as error code 52.

Further Information and Manual Repair

Method 1 – Run a complete scan for malware and spyware

Identifying and removing the viruses in the system registry and in the connected devices is the easiest method to fix the corrupted registry files.

Viruses such as spyware and malware infect the registry entries and eat up the files that lead to incomplete or missing data. This creates problems for installing external devices as the driver required to install them is not complete.

Method 2 – Use System Restore

The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work. Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error In addition, the ctfmom.exe Unknown Hard error may also occur due to incompatible drivers installed on your PC. Ctfmom is a process that identifies inputs such as handwriting, languages, and many more. It’s the one that controls the functions of background behavior. To resolve this issue, you need to first try to identify which application is the one that’s running the sihost.exe file. And if needed, you need to either update or reinstall or completely uninstall the problematic application.

Option 1 – Try to run the System File Checker

The SFC Scan or System File Checker, us a built-in utility in Microsoft Windows that can be found in the C:\Windows\System32 folder. This tool allows users to scan and restore any corrupted system files in Windows that might be causing the Unknown Hard error to appear. Before you use this tool, make sure to find out whether the sihost.exe on your computer is a Trojan that you have to remove or if it’s a file that belongs to a trusted Windows application. Once you have that sorted out, follow the steps below.

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

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 2 – Try to use System Restore

You can also try using System Restore. This is one of the ways you can use it to back up your PC. Since restore points are created automatically each week by System Restore, you can use System Restore to restore your computer back to an earlier good point in time.

Option 3 – Try to troubleshoot the error in a Clean Boot State

Putting your PC in a Clean Boot state can help you diagnose and troubleshoot the issues in your system. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the Unknown Hard Error.

• 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” checkbox 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” checkbox.
• 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.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

If you are trying to install or update Microsoft Edge on your Windows 10 computer but ended up getting HTTP Error 500 or Error 0x8004xxxx or 0x8007xxxx, then you’ve come to the right place as this post will help you sort this problem out. The aforementioned errors when either installing or updating the Edge browser occur due to a Network issue. There is actually a range of error codes that are associated with the network connection issue. These error codes include Error 500 or 0x80010108, 0x80040801, 0x80042193, 0x80042194, 0x800421F4, 0x800421F6, 0x800421F7, 0x800421F8, 0x80072742, 0x80072EE2, 0x80072EE7, 0x80072EFD, and 0x80072EFE. To fix them, there are several options you can try. You can try to run the Network Adapter troubleshooter or update or reset the Network Adapter as well as check and the proxy configuration.

Option 1- Try updating the Network Adapter Driver

Follow the steps below to update your Network Adapter Driver:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• From there, expand the list of all the network drives and update each one of them.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 2 – Run the Network Adapter troubleshooter

To run the Network Troubleshooter, refer to these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.
• Restart your computer.

Option 3 – Try to reset the Network Adapter

You can also try to perform a Network Reset to resolve the problem. This will reset the entire network configuration including your IP address. To perform Network Reset, follow these steps:

• Tap the Win + I keys to open Settings.
• From there, go to the Network and Internet section.
• Next, scroll down and look for “Network Reset” under the status pane.
• After that, click on Network Reset and then on Reset now to start resetting the network configuration. Once done, check if it is able to fix the error or not.

Option 4 – Try to fix the Proxy Settings

• In the Cortana search box, search for Internet Explorer and then click on the related search result.
• After that, tap the Win + T keys on your keyboard and click on Internet Options.
• Next, navigate to the Connections tab and click on LAN Settings.
• Then click on the Advanced button and delete all the entries in the list generated in the Exceptions section. And if the Advanced button is disabled because the “Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections)” option is disabled then you are good to go. Now proceed to the next step.
• Tap the Win + X keys or right-click on the Start button and select Command Prompt (Admin) or you could also search for “cmd” in the Cortana search box and right-click on Command Prompt from the search results and select the “Run as administrator” option.
• If a User Account Control appears, click on Yes to proceed. After that, type each one of the commands listed below, and don’t forget to hit Enter after you type each one of them.
  • netsh winhttp reset proxy
  • net stop wuauserv
  • net start wuauserv

• Now restart your computer and check if the problem is fixed or not by installing or updating Microsoft Edge again.
