Fix Netwtw04.sys BSOD Error in Windows 10

Blue Screen of Death errors or Stop errors are indications that something’s wrong with your computer. So when you encounter one, you must find out what the root cause of the problem is before it gets out of hand. One of the BSOD errors you might encounter on your Windows 10 computer is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” error.

As you know, system files or .sys files are some of the essential parts of the Windows operating system. It is a repository of system driver settings used by the Windows operating system in order to communicate with the connected hardware and devices. They are essential for the normal functioning of the operating system. A lot of Windows 10 users are facing this particular Blue Screen of Death error whenever they open an app or disconnect external devices from the system.

The Netwtw04.sys file is a part of the Intel PROSet/Wireless Wi-Fi software. And so when you might encounter two kinds of Stop errors for the Netwtw04.sys driver file such as:

  1. “DRIVER_IRQL_NOT_LESS_OR_EQUAL What failed: Netwtw04.sys.” – This kind of error message signifies that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high.
  2. “SYSTEM_THREAD_EXCEPTION_NOT_HANDLED What failed: Netwtw04.sys” – This error message indicates that the root cause of the error might be incompatible drivers with the operating system. In general, the root cause of the Netwtw04.sys BSOD error might be due to several reasons such as corrupted files, incorrect device driver configuration, malicious programs, outdated drivers, bad drivers, corrupted Windows Registry as well as some damaged or corrupted system files.

Whichever of the two error messages you got, you can try the troubleshooting options given below to fix the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error.

Option 1 – Try to rollback your Network driver

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
  • Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
  • Then select each one of them and double-click to open a new mini window.
  • After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
  • Now restart your computer to successfully apply the changes made.

Option 2 – Try to update the Network drivers

If the present Network driver is giving you a headache that is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error, then you need to update the Network drivers. To do so, here’s what you have to do:

  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
  • Then right-click on each one of the Network drivers and update them all.
  • Restart your PC and see if it helped in fixing the BSOD error.

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 3 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Netwtw04.sys failed BSOD error. 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

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 DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

  • Open the Command Prompt as admin.
  • Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
  • The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the CHKDSK Utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. 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

  • Wait for the process to be completed and then restart your computer.

Reliability Monitor is not updating or working
In case you don’t know, there is a built-in tool in Windows 10, known as Reliability Monitor that provides a day-to-day snapshot of the health of your system. It warns users of any looming issues or disasters before your computer breaks down finally. So obviously, Reliability Monitor is useful, however, there are times when it could behave incorrectly. For instance, it might fail to show you any updates even when they are installed. Thus, if you experience any malfunctions with the Reliability Monitor tool in Windows 10, read on as this post will guide you in updating or working in Windows 10. To fix the problem with the Reliability Monitor, there are several fixes you can check out. You can try to enable the data collection for Reliability Monitor or reset it, as well as put your computer in a Clean Boot State. For more information, refer to each one of the options given below.

Option 1 – Try to enable the Data Collection for Reliability Monitor

The Reliability Monitor tool uses data provided by the RAC Agent scheduled task and it will start to display a Stability Index rating and specific event information 24 hours after the system installation. The RACAgent scheduled task, by default, runs after the operating system is installed. And if it is disabled, it must be manually enabled from the Task Scheduler snap-in for MMC or Microsoft Management Console. Thus, you need to enable the Data Collection for Reliability Monitor to fix the problem.

Option 2 – Try to reset the Reliability Monitor

The next thing you can do to fix the issue with the Reliability Monitor might want to reset it to resolve the problem. If the Reliability Monitor is already open, you have to close it and open it again. After the reset is done, it may take up to 24 hours for the Reliability Monitor to display results again. This should fix the problem.

Option 3 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
  • 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” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.

Should you build a custom PC

Building your own custom PC system can be one of the greatest things you can do to your budget. Instead of going for a rebuild, we will go into detail about why building your own PC is a much better option. Also, note that if you do not possess enough technical knowledge about a topic there are plenty of stores that will offer you advice on components and after all, you can always get help from a friend.

Custom PC

So without further diversion from the topic, let us explore all the benefits of building a custom computer.

Building a custom PC is cheaper

At the first look, this statement does not feel right since when you look at the prebuilt systems you get a feeling that it is much cheaper than do it yourself variant and although CPU and GPU seem like a great deal I beg you to look under the hood on other components. Usually to lower price compromise would be made on other crucial components like SD or power supply, a PC case, or motherboard so even if you have a good CPU and GPU that will not matter much since other components would not be able to catch up with them. After all, prebuild computers will need to pay people who are building them and there is no way that will be cheaper if you just plain went and bought the same components yourself and install them.

When you are in control in choosing each component there is not only being cheaper online, it is flexibility with building itself. You choose which components you want to be stronger and which to be normal. Also, you can choose the exact model of the given component leaving you more in control and open to future upgrades.

More flexibility

Also, it may sound irrelevant but when building your own custom PC you can also choose which company you would like to purchase for each model, yes considering the CPU it is AMD or Intel but when you are buying a case, SSD, GPU, and other components choosing the right company for your needs is also the thing that should not be overlooked.

You can customize it the way you want

Not really a quality argument but with a custom PC build, you can choose would you like that RGB component or not, you choose do you like white or black fans, and many more things. You really can place a personal stamp on the computer making it indeed a personal computer.

You choose OS and applications

When you buy an already prebuilt PC, usually it comes with some sort of OS on it, sometimes it is freedos, Linux and sometimes it is Windows Home. When you get your hands dirty you can place whichever system you want on it and install applications that you use and know and some preinstalled typical apps.

Disable the Notifications for any Apps
Since Windows 10 introduced the concept of notifications, almost any application installed on your computer sends you one. However, there are times when too many notifications can be quite annoying. Although some of them are important, most of them are not and are only getting in the way of your tasks. So if you don’t like to be flooded with tons of notifications on your Windows 10 computer, say no more as this post will help you out in disabling notifications for any apps installed. And now with the new feature in Windows 10 called Focus Assist, you will be able to manage the level of notifications that you receive. This new feature also allows you to disable all notifications except for the ones from important or priority apps. You will just have to maintain a list of priority applications or you could also disable all the notifications except for the important ones like alarms. In addition, you could also set up some automatic rules such as the Focus Assist timings which means that you can make Focus Assist enabled for a certain period of time during the day or when you are duplicating your display or playing a game and whatnot. So if there is an application that keeps on spamming you with notifications, you can just disable the notifications for that application.

To get started on disabling notifications, refer to the steps given below.

  • Step 1: Go to Settings > System.
  • Step 2: From there, open Notifications and actions and then scroll down to the “Get notifications from these apps” section.
  • Step 3: After that, look for the application that you want to disable notifications for and click on the toggle button that corresponds to disabling notifications for that application. You could also click open to explore additional settings for that particular application.
Note: You can disable notifications or just the notification banners, your choice. Aside from that, you can also control the notification sound as well as its behavior when the computer screen is locked. What’s more, is that you can also adjust the number of notifications displayed in the Action Center or select the priority applications. As stated earlier, Windows 10 gives you control that allows you to customize every nook and cranny of the notification on your Windows 10 computer. Apart from applications, there are also other notifications-related settings that you can control including disabling notifications about tips, tricks, and suggestions as well as summary notifications from Windows Defender that you get every time you use or scan your computer.

Android malware spies while posing as a Update
New malware with extensive spyware capabilities steals data from infected Android devices and is designed to automatically trigger whenever new info is read to be exfiltrated. The spyware can only be installed as a 'System Update' app available via third-party Android app stores as it was never available on Google's Play Store. This drastically limits the number of devices it can infect, given that most experienced users will most likely avoid installing it in the first place. The malware also lacks a method to infect other Android devices on its own, adding to its limited spreading capabilities. However, when it comes to stealing your data, this remote access trojan (RAT) can collect and exfiltrate an extensive array of information to its command-and-control server. Zimperium researchers who spotted it observed it while "stealing data, messages, images and taking control of Android phones."

What happens when malicious software is installed

"Once in control, hackers can record audio and phone calls, take photos, review browser history, access WhatsApp messages, and more," they added. Zimperium said its extensive range of data theft capabilities includes:
  • Stealing instant messenger messages;
  • Stealing instant messenger database files (if the root is available);
  • Inspecting the default browser's bookmarks and searches;
  • Inspecting the bookmark and search history from Google Chrome, Mozilla Firefox, and Samsung Internet Browser;
  • Searching for files with specific extensions (including .pdf, .doc, .docx, and .xls, .xlsx);
  • Inspecting the clipboard data;
  • Inspecting the content of the notifications;
  • Recording audio;
  • Recording phone calls;
  • Periodically take pictures (either through the front or back cameras);
  • Listing of the installed applications;
  • Stealing images and videos;
  • Monitoring the GPS location;
  • Stealing SMS messages;
  • Stealing phone contacts;
  • Stealing call logs;
  • Exfiltrating device information (e.g., installed applications, device name, storage stats).

How does it work?

Once installed on an Android device, the malware will send several pieces of info to its Firebase command-and-control (C2) server, including storage stats, the internet connection type, and the presence of various apps such as WhatsApp. The spyware harvests data directly if it has root access or will use Accessibility Services after tricking the victims into enabling the feature on the compromised device. It will also scan the external storage for any stored or cached data, harvest it, and deliver it to the C2 servers when the user connects to a Wi-Fi network. Unlike other malware designed to steal data, this one will get triggered using Android's contentObserver and Broadcast receivers only when some conditions are met, like the addition of a new contact, new text messages, or new apps being installed. "Commands received through the Firebase messaging service initiate actions such as recording of audio from the microphone and exfiltration of data such as SMS messages," Zimperium said. "The Firebase communication is only used to issue the commands, and a dedicated C&C server is used to collect the stolen data by using a POST request."

Camouflage

The malware will also display fake "Searching for the update.." system update notifications when it receives new commands from its masters to camouflage its malicious activity. The spyware also conceals its presence on infected Android devices by hiding the icon from the drawer/menu. To further evade detection, it will only steal thumbnails of videos and images it finds, thus reducing the victims' bandwidth consumption to avoid drawing their attention to the background data exfiltration activity. Unlike other malware that harvests data in bulk, this one will also make sure that it exfiltrates only the most recent data, collecting location data created and photos taken within the last few minutes.

About Browser Hijackers

Browser hijacking is actually a form of unwanted software, commonly a browser add-on or extension, which then causes modifications in the browser’s settings. There are lots of reasons why you might experience a browser hijack; however commercial, marketing, and advertising are definitely the key purposes for their creation. Usually, it will force users to predetermined sites which are looking to increase their advertising campaign earnings. It may seem naive, but the majority of these sites are not legitimate and can pose a major threat to your online safety. Browser hijackers can also allow other harmful programs without your knowledge to further damage the computer. How to determine if your browser has been hijacked There are many symptoms that indicate the internet browser has been hijacked: the home page of your browser is changed suddenly; you find yourself constantly directed to a different web page than the one you intended; the main web browser settings are modified and unwanted or insecure resources are added to the trusted websites listing; unsolicited new toolbars are added to your web browser; you may find numerous pop-up adverts on your computer screen; your browser has instability issues or exhibits frequent errors; you can’t navigate to certain websites, such as computer security software related websites.

So how does a PC get infected with a browser hijacker?

Browser hijackers can enter a PC by some means or other, for example via file sharing, downloads, and e-mail too. Many web browser hijackings originate from add-on applications, i.e., toolbars, browser helper objects (BHO), or extensions added to browsers to provide them additional features. Some browser hijackers spread in user’s computers using a deceptive software distribution method called “bundling” (commonly through freeware and shareware). Some of the popular hijackers are VideoDownload Converter, Babylon Toolbar, Conduit Search, OneWebSearch, Sweet Page, and CoolWebSearch. Browser hijackers might record user keystrokes to gather potentially invaluable information leading to privacy concerns, cause instability on computers, drastically disrupt user’s browsing experience, and eventually slow down the PC to a point where it becomes unusable.
