Android malware spies while posing as a Update

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.

What is Solimba?

Solimba is a bundled executable program. It was created to be launched as a promotional tool to get advertisements loaded on a user’s system, upon installation. As a bundle, Solimba offers installation of various programs, with the objective of promoting various products and services. It utilizes unethical techniques, as in the case with adware tactics to influence or for want of a better word, hijack an Internet Browser to affect a website’s result on a search results page. In this assessment, Solimba distributed ads on Internet Explorer, Chrome, and Mozilla browsers, by hijacking various Internet Browsers to change the user's experience. (Images are shown below) Technical details about Solimba PUP include:

Digital Signature:  POPELER SYSTEM, S.L. Entry Point:   0x0000C1DC

Assessment of Solimba Potentially Unwanted Program

Solimba PUP is all about the ads. Once this executable is installed, it penetrates your computer system and sends ads all over your Internet Browser – Chrome, Internet Explorer, Mozilla Firefox, and the likes. For this assessment of Solimba.exe PUP, two installations were carried through. In layman's terms, I actually installed Solimba on two occasions to decipher the true nature of the PUP. It was shocking to find that both installations revealed different bundled programs and advertisements. In the first instance (as shown below), Solimba proved more aggressive in featuring ads for revenue advancements.

 Solimba employed aggressive advertising techniques

It’s important to note that hijacked results resulting from the installation of Solimba. This affected the results of the website on the Internet browser to boost its ranking, even without the use of a search engine. The advertisement displayed on the Internet Explorer search page routes the user to a software installation website. The utility tool in question was a “Windows 8.1 PC Repair” tool used to identify threats present on the Windows 8.1 OS. The advertisement displayed on the Chrome Browser search page routes the user to a health and beauty magazine website. This site advocates health and beauty, especially issues concerning weight loss. Several ads were visible on-site, displaying products to assist people in losing weight. During my installation of Solimba, the installation wizard underscored that four programs would be downloaded. These programs included N8Fanclub.com_KinoniRemoteDesktop, Lolliscan, PaceItUp, and SearchProtect. Interestingly, only two programs from the list were apparent or obvious. An N8Fanclub.com_KinoniRemoteDesktop file was made on the Desktop and SearchProtect was seen in “All Programs”, along with files stored on the computer’s Local Drive. The other programs that were “supposedly” installed remained concealed. A test was done to determine whether these were counted as extensions or add-ons to the varying web browsers but nothing was found on any of the tested browsers – Google Chrome, Internet Explorer, and Mozilla Firefox.

Description of 4 Installed Files

N8Fanclub.com_KinoniRemoteDesktop

When this file was initially found on the Desktop, a rootkit came to mind. A rootkit was used as a means to an end. Whoever was on the receiving end of this unwanted file would be able to connect to an infiltrated system without the knowledge of the user. After running the file to determine its behavior, nothing much happened. A message appeared indicating that the software couldn’t execute on the computer. That was pretty tricky since, to begin with, I didn’t place that specific file on the desktop but it came along with the territory and so I had to accept it. Further research online into N8Fanclub.com_KinoniRemoteDesktop proved very rewarding. A search of the entire file name was not able to do the trick so I had to do research on both terms separately. After landing on N8Fanclub.com, I was nicely asked to disable my adblocker. There seemed nothing harmful about the site. However, due to the fact that it was not what I initially installed, the program was an unwanted program. That’s exactly what Solimba does. It installs several other programs that were not requested by the user in an attempt to make money from advertising. The mere fact that this program got installed meant that it was to promote an online service.

KinoniRemoteDesktop

was a separate program. It was combined with N8Fanclub as a way to allow users to use their PC computer “as if they were sitting in front of it.” A user would be able to make use of a full web browser, watch Flash videos, play games, and even use office applications. This would be done from the user’s Nokia device. This is an advertisement at its best.

Lolliscan

This program did not allow me to see much since it didn’t leave a physical trace behind. However, during the installation, Lolliscan was listed as one of the four programs that would be installed. Overall, Lolliscan supposedly should be able to save people money since this form of the ad focuses on showing coupons when visiting sites such as Amazon. While this seems like a good deal, this ad will invade your personal space and distribute pop-ups at the most inopportune times.

PaceItUp

As the name states, PaceItUp is software added to a browser with the intent to speed your computer. Quite the contrary, PaceItUp does the total opposite since it installs bundled programs that slow down a computer system. PaceItUp is also known for displaying ads and tracking what the user does on his/her computer system.

SearchProtect

It’s known for hijacking your computer’s homepage. In fact, this addition is very stubborn and often possesses a challenge when a request to uninstall is made.

Further Information on Solimba

The second installation of Solimba also had its own dose of bundles to display. In comparison to the first installation, two programs from the bundle were different while two remained the same. two additional programs were installed along with the second installation of this bundle. These were dubbed Optimizer Pro and GamesDesktop. SearchProtect and N8Fanclub.com_KinoniRemoteDesktop remained triumphant and unbeatable. They were repeated within the installation.

BSOD or Blue Screen of Death errors are one of the most common errors you can encounter on your Windows PC. One of these BSOD errors is the “ACPI_BIOS_ERROR”. If you suddenly get this error, it means that there is some problem in booting the operating system from your hard drive or Windows was not properly installed on your PC. In addition, this error could also mean that there is something wrong with the CMOS battery located in the motherboard. Unlike other BSOD errors, the workaround for this error is a bit different as these workarounds require a bit more expertise in updating the BIOS as well as setting the correct boot configuration. If you know are capable enough in troubleshooting the problem, refer to the instructions laid out below to fix the BSOD “ACPI_BIOS_ERROR”.

Option 1 – Try to remove the SSD and update the BIOS

The first thing you have to do is to check the primary storage devices on your PC. If you have just installed a new hard drive or SSD recently on your computer, then it’s most likely the cause of the BSOD error. Moreover, you should also ensure that your BIOS is up-to-date to the latest available build.

• Remove the SSD/HDD and inject a different HDD that was already preinstalled in your Windows PC.
• After that, update the BIOS to the latest available build. After updating it, insert the old SSD/HDD and then try to boot your PC again. The problem should be fixed now. If not, refer to the next given option.

Option 2 – Try to check the CMOS battery and reset the CMOS module

As mentioned earlier, the CMOS battery might also be the one that’s causing the problem. It is a physical component of the motherboard and is a memory chip that contains all the settings configuration on your computer and is also powered by a battery. So if your battery loses power, the CMOS will be reset and as a result, all the configurations will be gone as well. It is also possible that the CMOS module is not properly working and every time things are saved, they are properly written due to the battery. That’s why you have to consider changing the CMOS battery and see if it fixes the problem. In addition, you also have to make sure that you completely reset the CMOS module and then try booting your PC again.

Option 3 – Try to check the BIOS settings

If the BIOS settings are incorrect, chances are that’s the reason why you’re getting the “ACPI_BIOS_ERROR” BSOD error. Every BIOS has different settings which you can make use of to enhance your computer experience. So make sure that your BIOS is up-to-date and that the settings are in accordance with your requirement. Another thing you can try is to disable the Legacy USB and the Legacy BIOS in the BIOS settings if you are trying to install a 64 bit Windows version. Make sure that you also enable AHCI before plugging in the installation drive on your PC. Moreover, ensure that your PC is using IDE or Integrated Drive Electronics mode instead of SATA or Serial Advanced Technology Attachment. Aside from that, try to check the extracted setup if it is in NTFS format, if it is, you should extract the ISO in FAT32 and use it to install Windows.

Option 4 – Try to reset the ACPI Compliant Control Method

ACPI or Advanced Configuration and Power Interface provide an open standard that operating systems can use to detect hardware, perform power management, as well as monitor the status of your device and provide information for other processes. Chances are, there are some misconfigurations with this module on your PC that lead to believing that there is no battery present. That’s why you need to reset it and see if it fixes the BSOD error or not.

• Boot your PC into Safe Mode.
• Tap the Win + R keys to open the Run dialog box.
• Type in “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After opening the Device Manager, go to the “Batteries” section and click it to expand it and then right-click on the “Microsoft ACPI-Complaint Control Method Battery” option and click on Uninstall.
• After you disable the module, click on any empty space and then click the “Scan for hardware changes” option.
• Then check if you can now boot your PC normally and without the BSOD error.

As you know, “JPEG” is one of the commonly used formats for image files which is a compression of digital images. It is one of the topmost used file formats by mobile phones and digital cameras and usually achieves a 10:1 compression with little visible loss in the quality of the image. There are tons of cases as of late, most particularly after the latest Windows 10 update where users were not able to open JPEG files on their PCs. Every time they try to open any JPEG file, they either get an error or nothing happens at all. This issue could be due to the default handler application for JPEG applications not being set or there could be some third-party image viewer not working properly. To fix this issue with JPEG files, refer to the troubleshooting options below.

Option 1 – Try to change the file type association

You need to check if the file type association of the JPEG files are correctly set or not since there are tons of third party programs that change the file type association automatically to themselves without your permission the instant they are installed and so if any of these third-party programs are broken, then naturally, your JPEG files won’t really open. That’s why you can try changing the setting to the default photo viewer instead of the third-party one. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type in “control panel” in the field and hit Enter to open the Control Panel.
• After opening Control Panel, click on the Programs category and select the “Default Programs” option from the menu.
• Next, select the second option “Associate a file type or protocol with a program” and then select the “Choose default apps by file type” option.
• After that, click on the .jpg file extension and choose the option from the pop-up.
• Now restart your PC to refresh all your programs and then see if it has fixed the problem or not.

Option 2 – Try to update your computer

Microsoft frequently releases updates to target bugs and improve users’ experience. And this particular error where JPEG files won’t open is already acknowledged by Microsoft so you need to make sure that your Windows 10 PC is updated to the latest released update and that there are no pending updates.

• Tap the Win + S keys to open Search and then type in “update” in the field and open the system setting from the search results.
• After that, check for updates and then download and install them if needed.
• Now restart your PC once the update is done and check if you can now open JPEG files.

Option 3 – Try to reset the Photos app via Settings

Resetting the Photos app could also help you in fixing the problem. Note that this option will reset all the configurations and your data associated with your Photos and makes the application go into a state when you first started using it and that this option will fix any discrepancies that your application might be experiencing right now.

• Tap the Win + S keys to open the search bar.
• Then type in “settings” in the field to open the Settings application.
• After opening Settings, click the “Apps” category.
• From there, a list of applications installed on your computer will appear.
• Navigate through these applications until you find the Photos app and then click on the Advanced options.
• Afterward, click the Reset button that appears on the next screen. Then a new pop-up comes up and will warn you that all the preferences, as well as sign-in information, will be lost. Click on “Reset” anyway to proceed in resetting the Photos app.
• Restart your PC once the reset is done.

Option 4 – Try to reinstall the Photos app

Before you start using other third-party image viewers just yet, you can try to reinstall the Photos app first. Thus, if there is something wrong with it, it will instantly get fixed right after it reinstalls. Just take note that this option requires administrative privileges so you need to be logged in as an administrator.

• The first thing you have to do is tap the Windows + S keys and type in “PowerShell”.
• Next, right-click on the file and click on the “Run as administrator” option from the context menu.
• Once PowerShell is opened, execute this command: get-appxpackage *Microsoft.Windows.Photos* | remove-appxpackage
• The command you just entered will remove the Photos app. After the process is done, go to the Microsoft Store and look for Microsoft Photos then download and install it again.

If you open any program in your Windows 10 PC such as Outlook and suddenly get an error message saying, “Failed to register a VB Script dll. Reinstall or run Regsvr32.exe Vbscript.dll to self-register”, read on, as this post will guide you on what you can do to fix it. The obvious solution to this problem is by re-registering the “vbscript.dll” file on your computer. Refer to the instructions given below to re-register the VB Script DLL file and to fix the error.

• Step 1: Open the Command Prompt as an administrator from the WinX Menu.
• Step 2: After opening Command Prompt, type in the following command and tap Enter on your keyboard.

regsvr32.exe vbscript.dll

• Step 3: Once you enter the command, it will re-register the VB Script DLL file using the Windows OS tool called Regsvr32 or regsvr32.exe. This tool is a command-line utility used to register and unregister OLE controls such as DLL and ActiveX (OCX) controls in the Windows environment. After the execution of the command, you should see the following pop-up on your screen which means the re-registering of the concerned DLL file has succeeded.

On the other hand, if re-registering the DLL file didn’t work, then you can try logging in using an administrator account and then register the DLL file again or you could also use the System File Checker to figure out what the problem really is and automatically fix it. System File Checker or 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 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.

As you know, the Mobile Hotspot feature is used to share the internet connection with other devices using Wi-Fi signals. These Wi-Fi signals are later caught by other devices using their Wi-Fi and then the internet connection is shared once they are connected. However, recently, some users reported that their devices weren’t able to see the Wi-Fi network even if their Wi-Fi is on. This kind of problem could be caused by several factors but one of the main ones include the frequency at which the Wi-Fi network is being broadcasted. If you are one of the users who are currently facing this problem, read on as this post will guide you on what you can do if the Mobile Hotspot or Wi-Fi connection does not show up or is not detected on your Windows 10 device. In most cases, there are only two frequencies at which a Wi-Fi network is broadcasted. They are broadcasted either at 2.4 GHz and 5 GHz. The ones that are broadcasted at 5 GHz need specific hardware since it is a newer technology compared to the ones at 2.4 GHz. There are several other pieces of equipment as well as electrical appliances that operate at 2.4 GHz that includes microwaves as well which causes disruption in the signal strength of the Wi-Fi network. Moreover, aside from signal interruption, this issue with the mobile hotspot might also have something to do with the network-related drivers in your computer. Thus, to fix the problem, here are some suggestions you should follow.

Option 1 – Try toggling the Network band or the frequency at which the Wi-Fi network is broadcasted

• First, open the Windows 10 Settings app and then navigate to Network & Internet > Mobile hotspot.
• From there, click on the Edit button located under the Network name, Network password, and Network band.
• After that, set the Network band to be at 2.4 GHz and then click on the Save button.
• Once done, restart the Mobile hotspot in your Windows 10 device as well as the Wi-Fi connection of the device that’s trying to connect to the hotspot.

Option 2 – Try running the Network Adapter Troubleshooter

If the first option didn’t work, you might also want to run the Network Adapter Troubleshooter. You can use it to troubleshoot the problem with the Mobile hotspot, to run it, follow 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.

Option 3 – Try updating the Network adapter driver

As mentioned, the problem could also be due to the network-related drivers. So it probably might be the reason why you’re mobile hotspot did not appear or was not detected. That’s why it is recommended that you update the Network adapter driver and to do it, refer to these instructions: 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.
• Restart your PC and see if it helped in fixing the issue with the mobile hotspot.

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.

The Disk Management tool in Windows 10 is a built-in tool that contains a user interface used to manage disk partitions to administrators of the computer. There are lots of instances when you have to change the size of the hard disk partition or reduce the size and so on. This is where the Disk Management tool comes in. It’s useful as the command line interface can be quite confusing and risky for some users. However, there are cases when this tool stops working. A proof of this the reports submitted recently by some Windows 10 users. Based on the reports, the Disk Management does not load or respond. If you are having the same problem, read on as this post will give you some suggestions on what you can do to resolve the problem.

Option 1 – Try restarting the Disk Management Service

• Tap the Win + R key combination to open the Run dialog box.
• Then type “services.msc” in the field and hit Enter or click OK to open the Windows Services Manager.
• Next, scroll down in the service list until you see the Virtual Disk Service. Double click on it to open and then select Automatic.
• Click on Apply and OK to save the changes made.
• If it hasn’t started yet, you can just click on the Start button to start the Service. The Virtual Disk service provides management services for disk, volumes, file systems as well as storage arrays.
• Now save all the changes you’ve made and restart your computer. Then check if you can now use the Disk Management tool without any problem.

Option 2 – Try using the System File Checker scan

System File Checker or 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 with good system files that might be causing some issues with the Disk Management tool. To run the SFC command, follow the steps given below.

• Boot your PC into Safe Mode.
• 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 3 – Try using the DISM tool

Aside from the System File Checker, the DISM tool can also help you resolve the issue with the Disk Management tool. It helps in restoring the health of your computer.

• Open the Command Prompt as admin.
• Then type in this command: Dism /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 using Diskpart and Fsutil

If both the System File Checker and DISM tool didn’t work, you can use command-line tools like diskpart and fsutil. These command-line tools are powerful but you need to be careful especially if you’re not that familiar with using them. However, it’s recommended that you have somebody who knows if you’re really inexperienced with this kind of stuff.

As you know, Windows 10 offers its users tons of options to log in to their computers. This includes simple and easy methods like PIN and complex ones like the Windows Hello Face unlock.

If you are currently facing this problem, worry not for this post will show you what you can do to fix this problem. There are actually two scenarios to this issue, you might encounter one where the login screen does not show up at all, while the second one is when the login screen shows up but there is no username or password box. There are several options you can check out to resolve the problem. You can try to run System Restore or try the combination of Ctrl + Alt + Delete keys. You could also try to enter a username and password to use the computer or disable Fast Startup or troubleshoot the problem in a Clean Boot State. You could also create a new User Account or run Fresh Start or run the Startup Repair. To get started, follow each one of the given options below.

Option 1 – Try using the Ctrl + Alt + Delete key combination

The first and simple thing you can do to fix the login screen is to tap the Ctrl + Alt + Delete keys and see if it makes the credentials appear or not. If not, proceed to the next given option.

Option 2 – Try running System Restore

If you aren’t able to boot into the desktop of your computer, you can run System Restore in the Advanced Startup Options by following these steps:

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.
• Once it’s done, restart your computer.

Option 3 – Try to turn off Fast Startup

Option 4 – Try troubleshooting the problem in a Clean Boot State

There are times when some conflicting programs installed in your computer might be the reason why there is an issue with the password box in the login screen of Windows 10. 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”.

• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 5 – Try to run Startup Repair

You might also want to run Startup Repair in fixing the issue with the login screen. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located on the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
• Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.
