What is DownloadAdmin/ Updateadmin?

As a digital creation of Blueis, the DownloadAdmin application peruses your computer system for programs/applications that are outdated. This program then makes the necessary updates/installation on your computer, as if it were the Administrator. While most people might consider this application harmful, scrutinizing the Digital Publisher/Creator of the application should be reason enough to remove DownloadAdmin (and any other associated program) from your computer. Why? Blueis is infamous for producing/distributing “adware type software”, according to herdProtect Anti-Malware. Is that not a plausible reason for you to remove applications associated with that publisher? Additionally, DownloadAdmin not only updates your outdated applications, but it installs additional programs - usually utility tools and search toolbars. This is a sly way to promote third-party software and to get ads loaded onto your computer system. Technical details about DownloadAdmin include:

Digital Publisher: Blueis Product Version: 4.0.0.1 Original File Name: DownloadAdmin Entry Point:  0x0000234A

Assessment of DownloadAdmin

For this assessment, the DownloadAdmin file was obtained and installed on a test computer. After the DownloadAdmin/Updateadmin application was installed, it made several modifications to the computer system. These modifications may class the newly installed file as a PUP (potentially unwanted program). Outlined below is what took place after the file was installed.

• Updated an outdated application installed on the computer

Subsequent to the update made by Updateadmin, I thought the PUP had run its course. However, it was not quite finished. It was after scanning the contents/programs of my Local Drive, I stumbled on an additional program, one that I did not download or install, at least not intentionally. As predicted, the DownloadAdmin application scanned through the computer system (in the blink of an eye), during installation and made adjustments to an application already installed. This program was the Mozilla Firefox. Since Mozilla Firefox was rarely used on the PC in question, the DownloadAdmin application thought it quite appropriate to revive the Mozilla Firefox browser, by replacing it with the latest or more contemporary version.

• Installed a search toolbar

While DownloadAdmin did request permission to install an updated version of my Browser, it provided no warning about installing a search toolbar. This is quite shady and deceptive. In addition to updating the Internet Browser, DownloadAmin also installed the SearchProtect toolbar (Conduit). This toolbar is no stranger to the market as I’ve encountered it on several occasions during my assessment of malware.

Should you remove DownloadAmin?

That decision is totally yours to make. However, here are some reasons why most people would consider that program unwanted

• It updates your outdated programs

In most cases, at least those I’ve seen, if a user has a program installed, they don’t necessarily want a new version of that program. In fact, this PUP could spell trouble since some programs, especially paid, require a license to use the software. When that program is updated/ upgraded, you might have to acquire a new license to get it to work.

• Unnecessary program

If you’re totally lackadaisical and loathe the idea of doing work yourself, this program might come in handy. Many users will update their computers manually by using Microsoft’s preinstalled/pre-programmed updater in their computer’s Control Panel. This option searches for and installs all the necessary programs to keep your computer safe and secure. The DownloadAdmin program only occupies needed space and resources on your computer. However, what’s good about this program is that it doesn’t operate at the start time so it doesn’t necessarily cause unnecessary lags on your computer.

• Modifies your search experience

By installing a search toolbar called SearchProtect, Updateadmin modifies or changes the browsing experience you’re accustomed to. SearchProtect hijacks your browser and changes your homepage to their choice while removing yours. This is often hard to reverse since the publisher created this software to remain once installed.

Hello and welcome to errortools articles. Today we will talk about some great and awesome tips and tricks for the command prompt. Commands which can make your life easier and your workday more pleasant. That being said let's dive in right into muddy waters and swim out with new knowledge.

Tip 1: Read Motherboard information

There are a lot of reasons why you would like to read information from your motherboard, maybe you would like to upgrade your BIOS, perhaps you would like to know the serial number, maybe even the version number. Well, you can, type the following code into the command prompt and you will receive all information about your motherboard.

wmic baseboard get product,version,serialnumber,product

Tip 2: Copy command output to clipboard

Getting information from the command prompt to a word processor, into an email or any other medium can be somewhat troublesome, usually, people tend to screenshot or write from a command prompt into another destination, which could induce errors, and let's be honest, it is not practical. You can copy command output directly into the clipboard ready for pasting it anywhere with | clip. So for example if you would like to paste the directory structure of your c drive command would look like: dir c: | clip, now output would be placed into the clipboard ready to be pasted anywhere needed.

Tip 3: Erase data permanently

When you delete data on your hard drive, what really happens is that files are marked with a marker which marks that space for new data writing, but the data itself is still present and can be brought back. This sometimes could impose problems but if you would type: cipher /w:c Windows will write random data over each marked file deleting it forever without means to be brought back.

Tip 4: Manage your IP address

If you would like to play with your IP address and do fancy stuff with it do the following: ipconfig /release to release your IP address ipconfig /renew to renew your IP address ipconfig /flushdns to flush down DNS information and enjoy a new browsing start.

Tip 5: Check to see are packets reaching the desired location

You installed a new LAN printer, or a new switch, maybe you want to check if your new site is up and running. Use ping destination in order to see if TCP packets are reaching desired information, you can use it with a specific address like ping 192.168.1.1 or you can type a web address, for example, ping google.com and see if a connection can be established.

Tip 6: Get information about a specific command

So you learned some command prompt commands, but you do not know all of their configuration or switches? No worries, just type command/? to get a list of available switches for it. For example ipconfig/? will write you a list of available switches for ipconfig command.

Tip 7: Link and execute multiple commands one after another.

Let us say that for example, you would like to copy files into a different folder, then rename some and delete others and you need to do a couple of times. Instead of writing command after command once each one is finished link them with && and they will execute one after another.

Tip 8: Scan and repair files.

In order to scan files and repair broke or corrupted ones write in the command prompt: sfc /scannow. Please know that this command can take a long time since it is solely dependant on the number of files, their size, and the power of the computer.

Tip 9: Manage and configure your computer energy

Command powercfg will let you manage and see the power configuration of your computer. Just write powercfg/? and see what you need and want to change or get information about.

Tip 10: Associate files with applications

Windows already has some file associations defined, and some applications take over some type of files but if you want to take control into your own hand use assoc command. For example assoc.txt= "APPLICATION NAME" will associate txt files with the provided application.

Tip 11: Hide files and folder.

Do you have some folder or file with information that you do not want to be seen when someone opens file explorer? Use attrib +h <name of file> and hide file or attrib +h /D <folder name> to hide folder.

Tip 12: Get a list of installed computer drivers

Want to know which drivers are installed in your system? Use driverquery and take a look.

Tip 13: Find and locate shared folders

have you shared a folder but forgot which one and where? Do not bang your head on the wall, we have a simple solution for you. just type in command prompt net share and see everything.

Tip 14: Run commands as an administrator

You do not have administrator privileges? Do you want to bypass common blockades?

runas /user:yourdomainadministrator command

That is all that we have for you today, I certainly hope you have found something useful here and that we have managed to teach you some valuable things.

If you are trying to run Windows Upgrade on your Windows 10 computer but suddenly interrupted by the error 0x800F081E – 0x20003, worry not for this post will guide you on how you can fix this Windows Upgrade error. This particular Windows Upgrade error is a Windows status code for CBS_E_NOT_APPLICABLE which indicates that some of the update requirements are missing or the files that are installed are already of a higher version compared to the ones that are still pending. In most cases, this error occurs when you try to upgrade to earlier versions of the Windows 10 N edition to a later version. Here’s the full content of the error message:

“0x800f081E-0x20003, The installation failed in the SECOND_BOOT phase with an error during BOOT operation”

In case you don’t know, Microsoft distributes special “N” editions of Windows in Europe and the “KN” editions in Korea. These editions are the same as the standard editions of Windows except that they do not have the Windows Media Player as well as the multimedia playback features. Thus, when the Windows Upgrade fails with the error code and error message and it doesn’t provide much information as to why the update couldn’t be installed, there is something you can do about it to fix the error. Since Windows uses generic error codes and so if you see the error code 0x800f081e, you have to check the error log first. For more details, follow the instructions laid out below. Step_1: You need to navigate to C:$WINDOWS.~BTSourcesPanther and from there look for the text file named “setuperr.log” and open it with a text viewer/editor program like Notepad. Step_2: After opening the setuperr.log file, you should see content that’s similar to this:

C:WINDOWSSoftwareDistributionDownload80b2677d6e15a2a206625bb25a7124feamd64_Microsoft-Windows-MediaPlayer-Package~~AMD64~~10.0.17134.1. Error: 0x800F081E 2019-09-10 20:26:57, Error SP Operation failed: Add [1] package C:WINDOWSSoftwareDistributionDownload80b2677d6e15a2a206625bb25a7124feamd64_Microsoft-Windows-MediaPlayer-Package~~AMD64~~10.0.17134.1. Error: 0x800F081E[gle=0x000000b7]

Note: From the content above, it is clear that the Windows Upgrade failed due to complete due to the Windows Media Player. It could be that the log file may contain other error messages and other error codes and if you see the error code 0x800f081e from the list, then you need to uninstall the Media Feature Pack. Step_3: You have to uninstall the Media Feature Pack.

• Tap the Win + R keys to launch the Run dialog box and type “optionalfeatures.exe” in the field and hit Enter to open the Windows Features wizard.
• Next, you need to wait until the list of Windows Features populates and then click on the + sign to collapse the folder of the Media Features.
• After that, uncheck the “Windows Media Player” option from the Media Features folder.
• Now click on the Yes and OK buttons to save the changes made and then close the Windows Features dialog box.
• Restart your computer and boot, try to run the Windows Upgrade process again, and check if the error is fixed or not.

Note: If the installation has been successfully completed, you have to go back to the Windows Features and enable the Windows Media Player again. And if you are using the Windows 10 N Edition, then you can just download and install the latest version of the Media Feature Pack for your Windows 10 N edition. On the other hand, running the built-in Windows Update troubleshooter could also help you resolve any Windows Update-related problems, including the error 0x800F081E – 0x20003. 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.

Hello and welcome everyone, today we will be talking about dreaded keyloggers, why they are dangerous, and how to know if you might have one in your system. Keylogger is a malicious application placed in your system and hidden with only one goal in mind, to get information about what are you typing and by that means for a person who infected you to get information about your credit card information or other sensitive data. They can be introduced into your systems in various ways and often can not be detected easily. Modern antivirus applications have ways of detecting them and removing but this tutorial aims to teach you how to spot them all by yourself since new keyloggers are produced daily and sometimes relying on antivirus alone is not enough. Unlike viruses and trojans, keyloggers are not heavy on system resources and you will not feel slow down on your computer if you have one which makes them harder to sport with regular work. Some of them can be even tracking you on the website and not even be physically present on your computer. Generally, we could categorize keylogger into 4 categories:

1. Web browser-based keylogger. Some websites would have CSS scripts, input web forms, or so-called man in the middle keylogger. Lucky for us even Windows defenders with the latest update can detect this type of keylogger and successfully deal with it and how keylogger itself is not present on our system we are safe.
2. General spyware keylogger. This keylogger is present in your system, usually, it infected it via email attachment, social media download, torrent download, some malicious so-called fixer application, etc. Most antivirus applications and windows defenders can detect these types as well and remove them successfully.
3. Kernel-level keylogger. This keylogger is a more dangerous type they tend to operate underneath Windows as a rootkit and can go undetected by antivirus and windows defenders.
4. Hypervisor-based keylogger. This is the most dangerous keylogger, they use virtualization techniques to hide and mask themselves as a replica of the operating system and they scan all keystrokes by the user. These are very rare keyloggers but they do exist.

If you suspect that you have a keylogger or just want to check your system for precaution reasons follow these tips and guides and luckily you will solve your issue in no time and your data will be safe.

1. Use Task Manager to find suspicious entries.

   Task manager is a great application implemented in Windows that is constantly monitoring and showing all services, applications, and processes currently running on your system and thus a great tool to monitor your system if you know how to use it. First, open task manager by pressing CTRL + SHIFT + ESC Then take a good look into it, try to find suspicious names, probably duplicate of running application, something like Windows logon application, or keylog or anything similar which seems out of ordinary. If you manage to find a suspicious running application right-click on it and close it. Also while you are in task manager jump into the startup tab and check to see are there some unusual applications starting with your Windows, if you find anything, disable it right away. This is the most simple and quickest way to get some information right away if you suspect to have some simpler keylogger in your system.

2. Use the command prompt to monitor your network.

   In order to check connections to your computer and find potential suspicious ones start the command prompt in administrator mode, press ⊞ Win + X, and choose command prompt (administrator). type in netstat -b and press ENTER. All website and application connections to your computer are now visible. ignore svchost, edge browser, windows store, etc ad check the IP of the remaining ones using the internet.

3. Use keystroke encryption.

   Install encrypting software and even if you have a keylogger, the application will encrypt each stroke and all that attacker will get is gibberish

Please remember to always download files from trusted sources, do not open unknown emails, and do not share your information publicly. Take common protection steps in order to protect yourself in the digital world.

The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work. Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error In addition, the ctfmom.exe Unknown Hard error may also occur due to incompatible drivers installed on your PC. Ctfmom is a process that identifies inputs such as handwriting, languages, and many more. It’s the one that controls the functions of background behavior. To resolve this issue, you need to first try to identify which application is the one that’s running the sihost.exe file. And if needed, you need to either update or reinstall or completely uninstall the problematic application.

Option 1 – Try to run the System File Checker

The SFC Scan or System File Checker, us a built-in utility in Microsoft Windows that can be found in the C:\Windows\System32 folder. This tool allows users to scan and restore any corrupted system files in Windows that might be causing the Unknown Hard error to appear. Before you use this tool, make sure to find out whether the sihost.exe on your computer is a Trojan that you have to remove or if it’s a file that belongs to a trusted Windows application. Once you have that sorted out, follow the steps 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 2 – Try to use System Restore

You can also try using System Restore. This is one of the ways you can use it to back up your PC. Since restore points are created automatically each week by System Restore, you can use System Restore to restore your computer back to an earlier good point in time.

Option 3 – Try to troubleshoot the error in a Clean Boot State

Putting your PC in a Clean Boot state can help you diagnose and troubleshoot the issues in your system. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the Unknown Hard Error.

• 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” checkbox.
• 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.
