One of the most useful utilities on a Windows 10 computer is the Windows File Explorer. It is undeniably one of the File Managers out there full of features on all the platforms. However, it is not without its issues and one of the most common ones most users encounter is when you are trying to open a folder or a location on File Explorer and it displays a message saying, “Working on it…” as it tries to load the content of that location or folder. This kind of issue mainly occurs to computers that run on an HDD although that doesn’t mean that it can’t happen to other computers that run an SDD. And so if the File Explorer on your Windows 10 computer keeps getting stuck on the “Working on it…” message along with a green animation bar moving very slowly while loading the contents of the folder, then it’s best if you follow the options given below to resolve this problem.

Option 1 – Try deleting the contents of the Automatic Destinations folder

• Tap the Win + R keys on your keyboard to open the Run utility.
• And then type “%AppData%MicrosoftWindowsRecentAutomaticDestinations” and hit Enter to open this location.
• From there, select all the files and tap the Shift + Delete key combination.

• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

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.

Pinned Windows 10 Taskbar Items. One of the most used interfaces in the Windows environment is the Taskbar. It is where users like to pin their most-used programs as well as shortcuts with extra privileges and automated tasks. In fact, it’s a lot better than the Start Menu. So if any Windows Update messes up with your computer, or if you’ve just switched to a different computer, setting up the Taskbar with the very same set of programs you used to have is definitely not an easy task. But worry not as this post will guide you on how you can backup and restore the items on your Taskbar either manually or automatically.

Manual Backup:

• Tap the Win + R keys to open the Run prompt.
• Then type “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” in the field and hit Enter to open the folder where you can see all the shortcuts or pinned items in the Taskbar.
• After that, copy all the files in the folder and paste them somewhere else as a backup. For instance, E:\Pinned Items Backuppinnedshortcuts.
• Next, tap the Win + R keys to open the Run prompt once more, and then type “Regedit” in the field and hit Enter to open the Registry Editor. When the User Account Control dialog box appears, click Yes.
• After opening the Registry Editor, navigate to this key – HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerTaskband
• Then right-click on the Taskbar folder and select Export.
• Now save the file with the .reg extension to another location like the E:\Pinned Items Backup folder and then name it.
• Close the Registry Editor.

Manual Restore:

Make sure to copy all the files to one of the drives if you are using another computer and then refer to the following steps.

• Tap the Win + R keys to open the Run prompt.
• Then type “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” in the field and hit Enter to open the same folder where you just copied all the shortcuts. Make sure to keep it open.
• Then open the backup folder where you saved all the pinned items and copy all the files there.
• Next, go to the Taskbar folder (%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar) and then paste your files in there. If you encounter a problem while doing so, just replace it with your own set of files.
• After that, go to E:\Pinned Items Backuppinnedshortcuts and then double click on tb-pinned-items.reg. If a User Account Control prompt appears, click Yes. This will add the registry file into the main registry hub. You will also get a dialog box that will confirm that data has been added to the registry successfully. Click OK.
• You should now see the items on the Taskbar. You have to restart Windows Explorer. To do so, end its process in the Task Manager.

Automatic Backup:

Backing up and restoring the pinned Taskbar items in your Windows 10 computer can be done automatically as well. But before you get started on the process, you need to understand what’s going on behind the hood first. First, you need to create two bat files and name them “Backup Pinned Taskbar Items” and “Restore Pinned Taskbar Items”. After you have that covered, refer to the following steps:

• Open the Notepad app and paste the following details and save it as “Backup Pinned Taskbar Items.bat.

REG EXPORT HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerTaskband “E:\Pinned Items Backuptb-pinned-items.reg” xcopy “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” “E:\Pinned Items Backuppinnedshortcuts” /E /C /H /R /K /Y

• After that, run the newly created bat file with admin privileges.

Automatic Restore:

• Open the Notepad app and paste the following details and save it as “Restore Pinned Taskbar Items.bat”.

REGEDIT /S “E:Pinned Items Backuptb-pinned-items.reg” xcopy “E:Pinned Items Backuppinnedshortcuts” “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” /E /C /H /R /K /Y

• After that, run the bat file with admin privileges.

Note: Just so you know, there is a drawback to this process as we’ve noticed that any pinned apps that were downloaded from the Windows Store don’t appear in these places and any items downloaded and installed separately from the internet and then pinned.

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.

• 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.

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.

Could not connect to the System Event explanation: Although logging into a Windows 10 computer may seem like a simple process, it’s actually not since the Windows operating system has built a mechanism in a way that any third party or malware intervention would not compromise access to the system. This mechanism is supported by numerous services, functions, and DLL files. And Microsoft has been taking this security to a whole new level with the introduction of Windows Hello. Recently, a number of users reported getting the “Windows could not connect to the System Event Notification Service service. Please consult your system administrator” error when logging into their computers. While some users also reported that although they can log in, they encounter the same error message from the Notification area. There are several options you can check out to resolve the error. You have to check the status of several Windows Services and make sure that they are running. You also have to reset Winsock as well as run the System File Checker scan.

Option 1 – Check for certain Windows Services

• First, you need to tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “services.msc” in the field and click OK or tap Enter to open the Windows Services Manager.
• After that, you will see a list of services and from there, look for the following Windows Services:
  • DHCP Client
  • System Event Notification Service
  • Windows Font Cache Service
• Now make sure that the Startup Type of each service is started and running.

Option 2 – Try resetting the Winsock drivers

• In the Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select the “Run as administrator” option.
• After opening Command Prompt, execute this command: netsh winsock reset

Note: If you are using IPv4, execute the “netsh int ipv4 reset” instead. On the other hand, if you are using IPv6, execute the “netsh int ipv6 reset”

• Now exit Command Prompt and see if the error is now fixed.

Option 3 – Try running System File Checker or SFC scan

You could also run System File Checker or SFC scan to fix the BSOD error. It 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

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.

• Reboot your PC.
