About Browser Hijackers

If you’ve ever downloaded software via the internet (shareware, freeware, etc,), it’s quite possible you’ve unintentionally installed unwanted programs on your PC. Potentially Unwanted Programs (PUP), also referred to as Potentially Unwanted Applications (PUA), are applications that you never wanted in the first place and often come bundled with freeware. Once installed, the majority of these applications can be tough to get rid of and become much more of an annoyance rather than a necessity. It is clear by its name – unwanted applications – but did not really constitute “malware” in the traditional sense. This is because, the majority of PUPs get into a computer not because they slip through the security holes, for instance, but because the users have got installed them themselves – 100 % unknowingly needless to say. A PUP might not be regarded as malicious or dangerous but nevertheless, it is a common reason for clunky OSs; some PUPs are a lot more aggressive by deliberately slowing down your PC.

The harm unwanted programs could do

PUPs come in various forms. Typically, they could be seen in adware bundlers that are known to use aggressive and misleading advertising. The majority of bundlers install many adware programs from a number of vendors, each of which features its own EULA policy. Safebytes Anti-Malware totally eradicates this threat and safeguards your computer against PUP or adware infection. Additionally, the majority of free programs nowadays come with a few unwanted add-ons; in most cases a web browser toolbar or browser modification such as a homepage hijacker. They can modify browser settings, change the default search engine, replace the default home page with their own websites, slow down internet speed, and also will damage your system as well. PUPs carry a dangerous bite if left unchecked. The most detrimental part of installing a PUP is the spyware, adware, and keystroke loggers that might hide inside. These are programs that don’t really do anything good for you; in addition to taking up space on your hard disk drive, they also slow down your PC, often modify settings without your authorization, the list of frustrating features goes on and on.

Tips on how to avoid getting a PUP

• When installing anything on your personal computer, always study the fine print, including the license agreement. Do not accept terms of use that are for bundled programs. • Use ONLY custom or manual install method – and never thoughtlessly click Next, Next, Next. • Use good antimalware software, such as Safebytes Anti-Malware which offers real-time protection against PUPs. • Think carefully before you download any kind of shareware or freeware. Turn off or get rid of toolbars and browser extensions you don’t actually need. • Always download applications from the original website. The majority of PUPs find their way onto your laptop or computer is via download portals, so steer clear of it entirely.

When you upgrade or update your Windows 10 computer but you suddenly got Error 0x8024a206 while trying to install the updates, it is due to a rouge update that was downloaded or because of some corrupted component in Windows. In case you don’t know, any file downloaded by Windows is verified for its integrity and if the files don’t pass the integrity test, then Error 0x8024a206 will most likely pop up during the Windows update or upgrade.

Option 1 – Reset the Windows Update components to the default

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 2 – Re-register DLLs related to Windows Update

DLL files, also known as Dynamic Link Library, are parts of applications that are separated from the core program so that they can be used again as well as independently be updated. The DLL files are loaded into memory and then used. Note that they have to be registered with Windows so they can be loaded. So if they’re not, the main program will fail. And this is the same with the DLL files related to the Windows Update. Thus, you need to register them in order to resolve Error 0x8024a206.

• In the Cortana search box, type “command prompt”.
• From the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that execute the commands listed below one after the other and don’t forget to hit Enter right after you key in each one of them.
  • regsvr32 JSCRIPT.DLL
  • regsvr32 MSXML3.DLL
  • regsvr32 WUPS2.DLL
  • regsvr32 WUPS.DLL
  • regsvr32 WUAUENG.DLL
  • regsvr32 WUAPI.DLL
  • regsvr32 WUCLTUX.DLL
  • regsvr32 WUWEBV.DLL

Note: You also have the option to run the commands together via a batch file. Simply create a batch file by copying all the commands in a notepad and then save it as “WURegisterDLL.bat”. After that, run the batch file and it will execute the commands all at the same time. Then you have to restart your computer and see if it has fixed the Error 0x8024a206.

Option 3 – Run the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Error 0x8024a206. 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 to 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 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update Error 0x8024a206. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Update and Shutdown/Restart is not working. As you have probably noticed, every time a new update is released and is downloaded on your Windows 10 computer, the operating system replaces the Restart and Shut down button with “Update and Restart” as well as “Update and Shut down”. This is most likely done so that you won’t miss the update. However, some users noticed that there are times when these buttons still continue to display the same message even if they’ve already performed the required operations such as shutting down or restarting their PCs. Cases like this happen when an update wasn’t installed properly or has failed which is why your computer keeps on prompting you to Update and Shutdown every time. To fix this dilemma, follow the options laid out below.

Option 1 – Try restarting the File Explorer

Restarting the File Explorer can definitely help you fix lots of issues especially when there is some issue with the user interface including this one.

• On the right side of the Taskbar, right-click on any open spot.
• Then click on Task Manager.
• Next, scroll down until you see Windows Explorer.
• After that, right-click on it and select Restart.
• If you are able to kill its process, you have to tap the Win + R keys to open the Run dialog box and type “explorer.exe” in the field, and hit Enter to launch the Windows Explorer.

Option 2 – Try running the Windows Update Troubleshooter

As you know, Windows 10 has various auto-repair built-in tools to help users fix small issues which used to get fixed manually. And in this case, you will need the Windows Update Troubleshooter to fix the issue.

• Go to Settings and click on Update and Security.
• From there, click Troubleshoot and click on Windows Update and then click the “Run the troubleshooter” option.
• After that, it will try to detect and automatically fix common issues in the Windows Updates which can be resolved by Windows itself. Note that the process may take several minutes before it completes so you need to wait until it’s done. Once it’s done, in case you have some pending update that wasn’t realized by the system early on, it will apply the fix right away and restart the Windows Update service.

Option 3 – Try setting the Power button to Shut down

In case the first two options didn’t work out, you can try changing what the power button does. To do that, refer to these steps:

• Go to Control Panel > Power Options.
• From there, select the “Choose what the power buttons do” option from the left side.
• Then set the Power button setting the “When I press the power button” option to “Shut down”. After that, it will shut your computer down without installing the updates but obviously, this is only a temporary fix.

Option 4 – Turn off your PC instantly without updating it

• Tap the Win + R keys to open the Run dialog box.
• Type in “shutdown -s -f -t 0” in the field and hit Enter if you really want to turn off your computer without any delay.
• You could also tap the Ctrl + Alt + Del keys and select Shut down from the bottom right menu.

Just like the third option, this is also only a temporary fix.

Option 5 – Try running the Windows Module Installer

The Windows Module Installer is a built-in service in Windows 10 that allows you to fix the stuck Windows Updates in your computer. To use it, follow these steps:

• In the Cortana search box, type in “cmd” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Once you’ve opened Command Prompt as admin, type the SC config trustedinstaller start=auto command and tap Enter.
• After the command is executed, you will see the “[SC] ChangeServiceConfig SUCCESS” message displayed on the Command Prompt console.
• Now exit Command Prompt and then check if the buttons are now back to normal.

Option 6 – Put your PC in a Clean Boot State

• 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” 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.)

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.

It is written for new guys and should also be maintained by the new guys to stay up to date. Looking forward to any questions and contributions, Freeplane development team

One of the most critical processes in the Windows 10 operating system is the Explorer.exe. And there are times when you might encounter an error that says, “System call failed”. You can encounter this error when you try to launch File Explorer, and in such case when the File Explorer does not work, it could cause issues in accessing folders and files on your computer. This kind of error pops up when the explorer.exe system file has become corrupted or if there is some process that interferes with its smooth functioning. To fix this error, you can try to restart the explorer.exe process, run both the System File Checker scan and DISM tool. You could also put your computer in a Clean Boot State or uninstall any programs you’ve installed recently. For more details, follow each one of the given suggestions below.

Option 1 – Try to restart the Explorer.exe process

The first thing you can do is try to restart the Explorer.exe process. To do so, refer to these steps:

• Next, expand the Task Manager window to see all the active processes.
• From there, look for the Windows Explorer process, right-click on it and select Restart.
• After that, check if the error is now fixed.

Option 2 – Run System File Checker scan

If restarting the explorer.exe process didn’t work, you can also try running the System File Checker or SFC scan to fix the error. 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 this command: sfc /SCANFILE=c:windowsexplorer.exe

Note: If you are using a 64-bit Windows operating system, enter the “sfc /SCANFILE=C:WindowsSysWow64explorer.exe” command instead.

• Wait until the process is completed and then restart your computer.

Option 3 – Run the DISM tool

You might also want to run the DISM tool. This tool is known to repair potentially corrupted files in your system as having them could also system issues like the “System call failed” error. To repair these corrupted system files, you can run the DISM commands:
