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.

Afraid of the growing threats online? As you should be. But we’re here to show you what kinds of malware are out there and what you can do to keep them at bay.

Malware definition

Malware comes from the term malicious software. It’s software designed to attack and exploit devices and networks to the advantage of the hacker who made it.

Malware can be transmitted in different ways. Most commonly this happens via infected USB drives, downloadable files or malicious websites. Depending on the type and ultimate goal, the consequences of a malware attack can range from negligible to catastrophic.

What kinds of malware are there?

1. Virus

A virus is typically spread via infected files, websites or links. It’s one of the oldest malware types and one of the most difficult to get rid of. That’s because, once activated, it replicates itself - hence the name. 

It can perform different kinds of attacks, depending on what the creator wants to achieve. The main characteristic of a virus is that it really doesn’t show itself until you activate the host. So that’s a scary thought for sure.

2. Adware

Sometimes an ad blocker isn’t enough to fight off unwanted ads. And some of them can, unfortunately, be malicious. They may redirect you to infected sites or prompt downloads of risky files. Even just opening a malicious site can lead to data theft.

So, definitely be careful when clicking around. Even if an ad seems completely legitimate, you can never be too sure.

3. Ransomware

Through ransomware, cybercriminals gain access to a user’s data and use it to extort them for money. Basically, the user is threatened with data deletion or even exposure if a ransom isn’t paid by a specific deadline.

This is a particularly nerve-wracking type of malware. If it targets an individual, it preys upon their sense of anxiety, fear, guilt and even shame. If it targets a business (which is a lot more common), it preys upon not only that business’s profit but also every single one of their customers and their data.

4. Trojans

This type of malware disguises itself very well as a legitimate-looking program. Once you download it, hackers can get full access and control of your device, data and network. They can even be hidden in games, apps and attachments. They cannot self-replicate, though, so we guess that’s… good news?

5. Worms

Worms can replicate, just like viruses, but you don’t need to actually activate the infected program for them to get going. They can be used for various purposes, ranging from data deletion to file encryption to support a ransomware attack.

6. Spyware

Spyware refers to malicious software that stays hidden on your computer and monitors your activity. The best-known type is keyloggers. This can be used to steal sensitive data like passwords and banking information.

7. Rootkits

Rootkits are among the most dangerous types of malware. They allow administrative access and full control of a device, which lets hackers continue hijacking all your data and monitoring your activity without your knowledge.

8. Botnets

Botnets are networks made up of bots - computers that cybercriminals have infected with malicious software. Bots and botnets give hackers remote access to users’ devices and allow them to spy on your camera, take screenshots, memorize passwords and launch Distributed Denial of Service attacks. This one truly makes your hair stand on end.

What can you do about it?

You know the old adage - better safe than sorry. And trust us, malware attacks are such a pain in the you-know-what that you really don’t want to be sorry.

Luckily, there are simple solutions that can shield you from most digital threats these days. What you want to be looking at is a solid antivirus program. Well, technically, you need an antimalware program, but since the latter evolved from the former, we still mostly refer to them as antivirus software.
The majority of antimalware programs these days don’t just shield you from potential risks online, but include additional features as well. For example, some Bitdefender antivirus packages also include parental control and a VPN. And Bitdefender is not just for PCs either - it offers protection for your beloved iPhone or Android as well. You can throw in a password manager in there too, for an additional layer of security.

If you aren’t too concerned about all these various threats or feel like you don’t need extra security, you can at least take a step to protect your information from being exposed to lurking cybercriminals as you’re browsing. This can be done through a good VPN like Surfshark, which hides your identity in the digital space and prevents your data from being tracked.

Choosing the right protective software is especially important if you have children with access to the Internet, since they’re unfortunately even more vulnerable to malicious attacks. If you aren’t sure what the right kind of antimalware program is right for you, you can reach out to us and we’ll be happy to help keep your entire household or office digitally secure.

The bottom line

The truth is that there’s no way to be 100% protected in the online world. Hackers are constantly coming up with new ways to infiltrate our devices. But malware-battling software evolves along with them and there’s still plenty you can do to keep risks away. Stay safe!

When you receive Error 0x800704C8 when trying to move a file inside Windows 10 operation is stopped and it can not continue leaving you with the file in its original location without a copy. Several issues can be the cause of this type of behavior and error and after some digging and analyzing we are bringing you various solutions for this error and how to fix it.

Ownership issues

It turns out that not having ownership of fie can cause this error and prevent you from copying it. For some reason, Windows can assume that file is owned or used by another application or process and thus prevents you from making a copy since you do not have ownership of it. Resolving this particular issue will require you to install a third-party application that is tailored for this kind of task. After some talk and research, we found out that there is a freeware application that can solve this issue quite fastly. Unlocker is the name and the download link is here. Once downloaded, install it and run it. Once inside the application browse to the location where you need to change the ownership, click on it to select it, and click OK. Use the No Action drop drown menu to select Move, then click OK

Antivirus Issue

As with other file and application issues, this error could also be a product of antivirus marking it inaccessible to Windows and thus preventing copy or move operation on it. note: Do not turn off Windows defender since it was proven that it is not the cause of this kind of error, so if you are using only Windows defender you can skip this solution. How temporary turning off each security suite is different and it depends on the application itself we can not cover in detail the procedure here. Go to your security suite manufacturer's website and get information there or if you want, go directly to applications and features inside Windows and uninstall the software.

Visual Studio issue

• If the file you are trying to move is part of a Visual Studio project then the issue can be linked directly to Visual Studio itself, luckily the solution is quite easy. All you have to do it to exit Visual Studio and then run it with administrator privileges.
• In order to run Visual Studio with elevated privileges locate its executable file and right-click on it.
• Choose properties and go to the compatibility tab
• Inside compatibility tab check box that says run this program as an administrator

Corrupted system files

If the previous solutions have not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

   SFC scan is a built-in Windows tool for solving corrupted system file issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC

People are becoming more and more concerned with their privacy and Facebook's flagship messaging application is caught between it all. While still widely popular it has becoming to lose its ground due to many unanswered questions about privacy encryption. Lucky for all of us there are alternatives for more secure messaging.

SIGNAL

Arguably the most secure of all well-regarded messaging apps, Signal is the favorite of the European Commission, as well as newsrooms around the world. While Signal doesn’t disclose how many daily or monthly users the app has, Google’s Play Store says it has been installed more than 50 million times. While using Signal, each voice or video call connected through the app includes full end-to-end encryption. Signal takes an extra step by hiding message metadata so that the location of the original message is missing. While it asks for your mobile number, that number isn’t used with your profile. Instead, it acts as a numeric username. Once registered, you will find 1-1 chat, audio, and video calls, disappearing or “secret” chats, and a privacy lock so nobody can access the app even if they have your phone. Best of all, it’s completely free to use.

TELEGRAM

One of the biggest competitors to Facebook Messenger (and WhatsApp), Telegram is a very strong alternative. With more than 400 million users, it offers an interface that should feel right at home for anyone coming from Messenger. Telegram offers some huge benefits over Messenger, including features like groups that can hold up to 200,000 members for a chat. There is no limit on your media or chat size, and you can share all types of files between users and in groups. From a privacy standpoint, Telegram has robust security, but it is worth noting that only “secret” messages are end-to-end encrypted and can self-destruct. Non-secret messages can be stored on Telegram’s servers so you can pick them up between your devices quickly. That’s a consideration worth knowing prior to making Telegram your default Messenger replacement. Telegram is free across all platforms.

THREEMA

Rising in popularity, Threema is another privacy-focused alternative that has quickly become a competitor to Facebook Messenger. This paid service ($2.99 on both App Store and Play Store) is a pay-once, use forever option. Once you pay the small fee, you gain all of Threema’s touted privacy options, like open-source end-to-end encryption for both messages and calls. Like Signal, Threema won’t require you to link any phone numbers or emails to your account. All chats are handled anonymously, and the service generates a random user ID when you first open and register for the app. No data is collected from any of your chats and no ads are shown. The Swiss-made app does have its own servers hosted in Switzerland, which do not store any chat messages. Another privacy benefit of Threema is the notion that all of your contact lists, groups, and user profiles are hosted on your device, not on the Swiss servers. Because of that, Threema can once again state that none of your personal info is stored anywhere they have access.

REevil is one of the most active and successful hacking groups connected to Russia and operating all over the world. The group recently demanded a huge bitcoin ransom for an attack targeting IT firm Kaseya in the USA. Since Tuesday blog and payment site run by REvil group cannot be longer reached without any kind of explanation or why. The reason behind the disappearance is unknown but has sparked speculation that the group may have been targeted deliberately by authorities. US President Joe Biden said he raised the issue with Vladimir Putin during a phone call on Friday, after discussing the subject during a summit with the Russian president in Geneva last month. Mr. Biden told reporters that he had "made it very clear to him...we expect them to act" on information and also hinted the US could take direct digital retaliation on servers used for intrusions. The timing of Tuesday's outage has sparked speculation that either the US or Russian officials may have taken action against REvil - though officials have so far declined to comment and cyber experts say sudden disappearances of groups are not necessarily uncommon. The development comes after a series of high-profile ransomware attacks which have hit major US businesses this year. The FBI accused REvil - also known as Sodinokibi - of being behind a ransomware attack on the world's largest meat processing company JBS last month.

There are various complex tasks that take place under the hood while you upgrade or clean install the Windows operating system on a computer. Because of its complexity, there are times when you might encounter some errors when you upgrade or clean install Windows 10. One of the errors you could encounter is the error that states, “Windows could not prepare the computer to boot into the next phase of installation. To install Windows, restart the installation”. This error does not only occur in Windows 10 as it could also occur on the other versions of Windows. There are a lot of possible causes for this error. It could be due to incompatible BIOS, corrupted system files, improper installation media or it could also be due to excessive hardware plugged into your computer and so on. Whatever the cause is, here are some potential fixes you need to check out to fix the problem.

Option 1 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the error.

Option 2 – Try to update the BIOS

As you know, the BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version in your computer.
• Now restart your computer to apply the changes made.

Option 3 – Try to reconfigure all the created partitions

You could also try to reconfigure the partitions by deleting and recreating all the available partitions on your computer and then see if it fixes the problem.

Option 4 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

If you are testing your headphone or your speaker but all of a sudden encountered an error that says, “Failed to play test tone” in your Windows 10 computer, worry not for this post will walk you through how you can fix this problem. The test tone is used to check the right-left balance of the headphones and speakers in your computer, however, if you are not able to use it, there are several options you can check out. You can try to run the Playing Audio troubleshooter or restart the services that are related to Windows Audio. Aside from these, you could also disable Audio Enhancements or you could also change the default test tone rate and bit depth.

Option 1 – Try to run the Playing Audio Troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to restart the Windows Audio-related services

The next thing you can do to fix the problem is to restart the services related to Windows Audio. Although the audio services start automatically on every system boot, there are times when they might fail to start. Thus, you can start these services manually by following these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Services Manager.
• Then look for the services named “Windows Audio” and “Windows Audio Endpoint Builder”.
• Double click on each one of these services and check if their Service Status is set to Running or not and also check if the Startup Type is set to Automatic.
• If none of the services are running, just click on the Start button and select the Automatic option from the drop-down menu.
• Now click on the Apply and OK buttons to save the changes made and then check if the error is fixed.

Option 3 – Try to update the Audio driver

You might also want to consider updating or the Audio driver as it could help in fixing the error.

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.
• From the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the driver.
• Then also click on the option, “Search automatically for updated driver software.

You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 4 – Try changing the default test tone rate and bit depth

Windows selects a default test tone rate and bit depth depending on your headphone or speaker. This allows you to look for the best sound quality from your audio output device. So if your headphone or speaker has some problems with the default settings, then it’s no wonder why you’re getting the “Failed to play test tone” error. To fix this, you can try to change the default test tone rate and bit depth by following the steps below.

• First, you need to open the Windows Settings panel and then go to System > Sound.
• Next, look for the Device properties option located on your right-hand side and click on it.
• After that, select the Additional device properties option and go to the Advanced tab.
• From there, select a different test tone rate and bit depth and then click on the Test button.
• Once done, check if it was able to fix the problem or not.

Option 5 – Try disabling the Sound or Audio enhancements

To make your operating system’s specific hardware sound nothing but perfect, both Microsoft and third-party vendors have shipped audio enhancement packages which are usually referred to as “Audio Enhancements” in Windows 10. However, there are instances when instead of improving the sound or audio quality of your computer, it can cause problems so to fix the problem you need to turn off these audio enhancements. How? Simply follow the steps below.

• Type in “Sound” in the taskbar search and then from the list of results, select “Sound Control Panel”.
• After clicking Sound, the Sound properties box will pop up. From there, go to the Playback tab and right-click on the default device i.e. Speakers or Headphones then select Properties.
• After that, the Speakers properties box will appear. From there, go to the Enhancements tab and select the checkbox for the “Disable all enhancements” option.
