About Browser Hijackers

Browser hijacking is a type of unwanted software, often a web browser add-on or extension, which causes modifications in web browser’s settings. Browser hijackers are capable of doing more than just modifying homepages. In general, browser hijacking is utilized for earning advertising revenue from forced ad mouse clicks and site visits. While it may seem naive, all browser hijackers are dangerous and thus always classified as security risks. When the malware attacks your laptop or computer, it starts to mess things up a whole that slows your system down to a crawl. In the worse case, you may be pushed to deal with serious malware threats as well.

How one can know whether the web browser is hijacked?

The common symptoms that suggest having this malicious software on your computer are: the browser’s home page is modified; you find yourself regularly directed to some other webpage than the one you actually intended; the default web browser settings have been modified and/or your default search engine is altered; unsolicited new toolbars are added to your web browser; your internet browser displays endless pop-up ads; web pages load slowly and often incomplete; you can’t navigate to certain webpages, like computer security software related sites.

So how does a browser hijacker infect a computer?

Browser hijackers may use drive-by downloads or file-sharing networks or an e-mail attachment in order to reach a targeted PC. They could also be deployed via the installation of an internet browser toolbar, add-on, or extension. A browser hijacker could also come bundled up with some freeware that you unintentionally download to your PC, compromising your internet security. Some of the most popular hijackers are EasyDirectionsFinder, Babylon Toolbar, Conduit Search, Sweet Page, OneWebSearch, and CoolWebSearch.

Browser hijacker removal tips

Some browser hijacking could be easily reversed by discovering and eliminating the corresponding malware software through your control panel. Sometimes, it can be a tough task to discover and eliminate the malicious component since the associated file will be running as part of the operating system process. Moreover, browser hijackers could modify the Computer registry therefore it can be quite tough to restore all the values manually, especially when you’re not a very tech-savvy individual. Industry experts always suggest users eliminate any malware including browser hijacker with an automatic removal tool, which is better, safer, and quicker than the manual removal solution. SafeBytes Anti-Malware could counter persistent browser hijackers and give you active PC protection against all types of malware. Together with the antivirus tool, a PC optimizer, such as SafeBytes Total System Care, can help you in deleting all related files and modifications in the computer registry automatically.

The store is not downloading Apps: As you know, the Windows Store is one of the places where you can download Windows apps. However, there are times when you might not be able to do so for some reason. For instance, if you search for an app and click on the get it now button, instead of downloading the app, nothing happens and there are also cases when the download will start but the page will refresh after half a second. When this issue happens, you won’t be seeing any error message or warning at all. So you’ll just have to look at the download get started where the page will refresh and you’ll be back at the Get button. This issue in the Windows 10 Store only happens for a few apps so even though you are able to download some apps, you might be able to do on other ones. Note that the apps affected are random and there is no specific set of apps that cause this issue while downloading and that this problem will repeat again each time you click on the Get it now button. This issue is definitely caused by Windows itself and has something to do with a bug in the Windows store which was brought by the latest Windows Update. It’s already a known issue among other Windows 10 users who are also suffering the same dilemma. So until Microsoft releases another update to fix this bug, you will have no choice but to deal with it in the meantime. On the other hand, you can also try a couple of suggestions laid out in this post. Follow the steps in every option given below to fix the issue with the Windows 10 Store.

Option 1 – Try signing out from the Microsoft Store

A lot of Windows 10 users were able to resolve the problem by simply signing out and signing back into the Microsoft Store. How? Follow these steps:

• Go to the Microsoft Store.
• Next, go to the Get page of the app you were trying to download.
• And then click on your account picture located in the top right corner of the window and select your account.
• Sign out from your account and after that, click the Get button to download the app.
• After that, a new window will appear where you’ll have to select your account and click on Continue.
• Now enter your credentials. Once you do, the app should be downloaded automatically after you’re signed in. And that’s about it.

Note: Keep in mind that this option is merely a temporary solution to the problem and once you close the Microsoft Store and open it back again, you will be back to square one.

Option 2 – Wait for the Windows Update

As mentioned, this is already a known issue and a lot of Windows 10 users have already complained about it to Microsoft so a bug fix will be soon released in the latest Windows Updates.

TPM, also known as Trusted Platform Module, is a specialized chip used for security as well as encryption of users’ private data like Fingerprint, Facial data, and many more. TPM also comes with a Management Console and if you are not able to load the Management Console and you got the “Cannot load Management Console” error instead, read on as this post will guide you in fixing the problem. This type of issue usually happens when you clear or disable the TPM using the settings in the BIOS and so when you run the Trusted Platform Module Management console, you encounter the error. To fix the “Cannot load Management Console” error in your Windows 10 computer, here are some options you should check out.

Option 1 – If TPM is cleared in the BIOS:

If the Trusted Platform Module is cleared in the settings of the BIOS, you have to close and restart the TPM Management console or TPM.msc once again. It could be that the TPM Management has to reload the changes again after you’ve made them which is why you encounter the “Cannot load management console” error.

Option 2 – If TPM is disabled in the BIOS:

If you opted to disable TPM using the BIOS settings or you have turned it off by accident, then you have to enable it back and you have two options to do that – you can either enable TPM from the BIOS or using the Windows PowerShell. For more details, refer to the instructions below.

Enabling TPM from the BIOS:

• You need to first reboot your PC and then go to the BIOS.
• From there, look for TPM under the security options and in case the TPM management option has been disabled or greyed out, refer to the sub-steps given below to make it active again
  • Enable the Admin password in the BIOS.
  • Then go back to the TPM settings and check if the TPM management is already available.
• After that, you should now be able to enable TPM. Remember that it’s always a good idea to have an ADMIN password for your BIOS as it makes sure that no one can change the settings in your computer BIOS and Security level options.

Enable TPM via Windows PowerShell:

• This second option is a lot easier compared to the first one if you have admin privileges. So once you’ve opened the Windows PowerShell with admin privileges, you need to run the following command:
  • $tpm = gwmi -n rootcimv2securitymicrosofttpm win32_tpm
  • $tpm.SetPhysicalPresenceRequest(6)
• After you execute the commands given above, you need to restart your computer.
• Now, once your computer has restarted, you need to accept any BIOS prompts and then check if the “Cannot load management console” error is now fixed.

Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. It can be found on 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.

Option 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• 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.

• Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.

If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• 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. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
• Then go to the Startup tab and select Microsoft OneDrive and then click Disable.

If you have multiple keyboards, things can get quite tricky. There are times when the keyboard language changes on its own since the keyboard changes while you are typing. The thing is, the keyboard changes because sometimes we accidentally tap shortcuts like Win key + Space key or Alt + Shift or Ctrl + Shift which changes the keyboard pairs or language. Thus, if your keyboard language changes on its own, there are two ways to resolve it. First, you have to make sure that Windows 10 does not add keyboards without your permission. Second, you have to make sure that the shortcut keys don’t change the keyboard language. This second option is what we’re going to discuss in this post. You need to first set a different input method for each app window. To do that, you have to disable the change in layout. Refer to these steps:

• Go to Settings > Language and input.
• Next, type “switching input methods” to open the Advanced keyboard settings with this option inside.
• After that, select the checkbox labeled as “Let me set a different input method for each app window” and then click the Save button.
• Restart your computer.

Now that you’ve disabled the change in layout, you now have to find the keyboard settings. Just go to Settings > Devices > Typing > Advanced Keyboard settings. From there, you have the option to select which keyboard is going to be used for any app. When you change the keyboard every time you use an app, usually, Windows remember it so that you won’t have to set it up all over again. In addition, the Advanced keyboard settings page also allows you to override the default input method which could be different from the first one in your language list. Aside from that, there is also a Language bar option that comes in handy as you can quickly switch between keyboards. And if you removed it, you have the option to restore the language bar back as well. Now all that’s left for you to do is to change the Language Settings under the Administrative tab. A user from a forum that came up with this solution, reported that the issue occurred when he started typing in some program with non-Unicode characters which caused Windows to use the default system local language to interpret these characters even though the language is unavailable in the Language bar. To change the Language Settings under the Administrative tab, follow these steps:

• Go to Settings > Time and Language > Language > Administrative language settings.
• After that, click on Copy Settings under the Administrative tab.
• Now make sure that all the Display language, Input language, and Format are English (United States) or any language you prefer.
• Then mark the two checkboxes in “Copy your current settings to Welcome screen and system accounts & New user accounts”.
• After that, click OK and then exit.

Note: You also have the option to disable those shortcut combinations which can change your keyboard settings accidentally.
