Trojan. Kryptik is a malicious computer infection known as a Trojan horse. Trojan. Kryptik can load at startup and recreate itself which makes it difficult to manually remove from the infected computer. Trojan. Kryptik can compromise the infected system by allowing a remote hacker to gain access without the user's permission or knowledge. Trojan. Kryptik can also lead to the infection of other unknown malware parasites.
Trojan.Kryptik creates the following registry entry or registry entries:
The Google Chrome browser checks the SSL Security Certificate of the website that you are trying to open. However, if Chrome is not able to check the certificate then you might encounter an error related to the SSL Certificates which you might face when browsing the web. This particular error is the ERR BAD SSL CLIENT AUTH CERT error which is caused by many factors such as the computer’s Time, Cached Data is corrupt, Date is out of sync, as well as third party software installed in your computer is the one that’s blocking the site and many more.
The ERR_BAD_SSL_CLIENT_AUTH_CERT error might also be coming from the website’s end. It could be that the server is rejecting the certificate the client website is sending. The certificate might have already expired or the server may not trust its issuer – whichever the case may be, here are some options you can check out to fix the error.
Option 1 – Sync Date and Time
The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the ERR_BAD_SSL_CLIENT_AUTH_CERT error. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.
Right-click on the Taskbar and click on the Adjust Date and Time option.
Next, click on the Sync Now button to synchronize the Date and Time with the Microsoft Servers.
Now make sure that the Time Zone that’s set on the same page is correct.
Option 2 – Try clearing the browser data
There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BAD_SSL_CLIENT_AUTH_CERT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.
Open your Google Chrome browser.
After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
Now select every checkbox that you see and click on the Clear browsing data button.
Then restart your Chrome browser and check if you can now open any website or not.
Option 3 – Try to check and fix any possible conflicts with third-party programs
Third-party programs like internet protection software could be interrupting the connection and causing the error. For some unknown reason, your antivirus program or firewall might be detecting the webpage you are trying to open as malicious or with less credibility which is why it is blocking the browser from opening the website. To fix that, if you have third-party programs installed like VPN, security software, or any add-on, or firewall, you can disable them temporarily and see if it fixes the problem and you’re able to pull up the website. After a while, you have to enable them back and configure their settings so that the website won’t get blocked again.
If you were using Google Chrome when you got the ERR_BAD_SSL_CLIENT_AUTH_CERT error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on.
If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.
Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
Restart the browser.
On the other hand, if you were using Firefox when you go the error, here’s what you have to do.
Open Firefox and in the address bar, type “about:config” and hit Enter.
If a warning appears, just click on the “I accept the risk!” button to proceed.
Next, type in “TLS” in the search field and hit Enter.
Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
Now click OK and restart Firefox and do the same thing with SSL.
Option 5 – Try to update Google Chrome
You might also want to try updating your browser to its latest version and have it installed in your computer. After you install the update, check if you can now open the website you were trying to open earlier.
Option 6 – Get rid of any conflicting browser extensions
Open Chrome and press Alt + F keys.
Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
Click the Recycle bin and select Remove.
Restart Chrome and press Alt + F keys again.
Proceed to On Startup and mark Open a specific page or set of pages.
To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.
Note: If removing the browser extensions or toolbars didn’t work, you can also try to reset your Google Chrome browser.
Open Google Chrome, then tap the Alt + F keys.
After that, click on Settings.
Next, scroll down until you see the Advanced option, once you see it, click on it.
After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
There are times when the Windows Search results do not include what you want to search. However, if you are trying to search for something that’s located on your desktop and Libraries, they would appear right away on the search results. Actually, the issue is not with the search but with the list of files and folders that Windows can index. If you encounter this issue, read on as this post will guide you on how to fix it.
The Windows 10 operating system, ever since Windows v1903 was released, offers two kinds of searches – the classic and the enhanced search. You may have to add more folders to the classic search or use the enhanced mode to resolve the issue. In other words, to fix the problem with the Start Menu Search, you can try to enable the Enhanced Mode or add folders to the Class Search or remove the excluded folders, as well as run the Search and Indexing troubleshooter. For more information, refer to each one of the options provided below.
Option 1 – Try to enable the Enhanced Mode
To fix the problem, you have to enable the Enhanced Mode search and configure the folders you want to be indexed. How? Follow these steps:
First, you have to go to Settings > Search > Searching Windows.
Next, select the radio button for the Enhanced option.
After that, select the folders you want the Windows Indexer to exclude from the Enhanced Search mode.
Option 2 – Try to add folders to the Class Search
If you don’t want to enable the Enhanced search mode, then you might want to add folders that are important to you. All you have to do is configure the Search Indexing Options by following these steps:
Go to Settings > Search > Classic and from there, click on the “Customize search locations” option.
Next, click on Modify in the pop-up window that appears.
Then add drives and folders that are important to you. Once the indexing is completed, Windows will be able to find the file and display it in the search results.
Option 3 – Try removing the excluded folders
If you have already enabled the Enhanced mode but your files still don’t appear, then you might want to check out the excluded folder list.
The first thing you have to do is go to Search and from there, you will find a list of folders under the Excluded folder list.
Next, click on the excluded folder that you want to remove by clicking on the “Remove Excluded folders” button.
If you are using the Classic search, you have to check if the index has restrictions on the file type. You can find it in Advanced options > File Types.
Note: If you want to search in Documents, you could also enable the Index Properties and File Contents. This should resolve the problem.
Option 4 – Try to run the Search and Indexing troubleshooter
You might also want to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for the Windows Start Search are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter.
Manually cleaning your PC registry may be the worst or best thing you ever decide to do. Registry keys that lie around on your computer, unused, can cause your computer to lag. This can end up in your computer not being able to load the easiest of programs and being slow at loading anything, let alone something that would take up a decent amount of memory.
If your computer has slowed to almost an absolute stop, it is most probably the registry’s fault and the only option then is to clean it. You can get programs to do this for you, but they can be riddled with inaccuracies and viruses that could harm your computer even more.
This is why some people choose to manually edit their computer. However, this is not without its flaws.
Registry Keys
Registry keys tend to have really long names.
These names will be full of numbers and hyphens and will most likely give you no indication of what they do. Even some computer experts find it hard to understand what every computer’s registry keys do.
This can make it very hard to see which ones are causing the problem; and if you don’t know what’s causing the problem, then there is no way you will be able to fix it.
Some registry keys will be completely menial in what they do but some could be vital to even allow Windows to work on your computer.
Manual Registry Repair
Registry keys can also cause huge problems if you manually delete the wrong one.
A lot of registry cleaners have the option to revive a key that they have deleted on you, which means that fixing an error that they made would be easy enough to do. However, when you manually delete registry keys, it will be an awful lot harder to get them back to work again afterward.
This can cause your computer many problems and if you delete even one wrong key it is possible your computer will not even start. With the horrid naming system they have as well, it makes it very hard to determine what is important and what is not, which means it is all too likely that you will delete something important.
However, those are the risks you have to take when you are cleaning out your registry. A registry cleaner has the same likelihood of messing with your computer and deleting something wrong that you have, so it is the same either way however a registry cleaner will do it with less hassle.
But, some people say that if you do it yourself, it’s more likely to be right; that is why they prefer to do it manually and that is alright.
Conclusion
So, if you are manually deleting your registry keys that are unused, you’ll have to use a program that comes with Windows known as ‘regedit.exe’ which is incredibly difficult to use but may just be worth the hassle in the end.
So, you don’t really need to put up with a slow computer, but be careful when messing with your registry manually!

In case you don’t know, new support has been added by Microsoft to Windows 10 that now allows users to turn off or on the Mobile Hotspot remotely. The Mobile Hotspot feature, known earlier as “Virtual Networks”, was first introduced with the initial release of Windows 10. With this new feature to remotely turn on or off the Mobile Hotspot in Windows 10, users can just use the Bluetooth on their mobile phones to turn off or on the Mobile Hotspot even when their Windows 10 computers are out of their reach.
To turn off or on the Mobile Hotspot feature in your Windows 10 computer remotely, there are two options you can try. First, you can do it using the Windows 10 settings app or using the Registry Editor. To get started, refer to the following options.
Option 1 – Turn off or on the Mobile Hotspot remotely via Windows 10 Settings app
First, you need to open the Windows 10 Settings app and from there go to Network & Internet and then go to the Mobile Hotspot section.
After that, scroll down to the “Turn on remotely” section.
Once done, make sure that the toggle button is set to ON and that the Bluetooth of both devices is turned on and paired as well. This should enable the feature to turn on or off the mobile hotspot remotely.
Option 2 – Turn off or on the Mobile Hotspot remotely via Registry Editor
Before you get started with the second option, make sure that you create a System Restore point first. Once done, proceed to the following steps:
Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then hit Enter to open the Registry Editor.
Next, navigate to this registry path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWcmSvcTethering
From there, look for the DWORD named “RemoteStartupDisabled” and set its Value data to be “0”. This will enable the feature that will allow you to remotely turn on or off the mobile hotspot in your Windows 10 computer. To disable it, just set its Value data to “1”.
Spying via some malicious app on the target phone is not a new thing but it can be very uncomfortable and even against the law in some countries.
Infecting the target phone can be done in various ways, another person can intentionally download and install applications on it, and you can install them via some phishing attacks or by an online scam. Once installed this piece of software presents a very serious invasion of privacy since it can track text messages, track phone location in real-time, record calls in real-time, eavesdrop on calls, take control of the camera and microphone, and many other applications.
Here are some common symptoms of mobile phones infected with spyware.
Symptoms of spyware
Random reboots Slow performance Strange text messages Overheating Unusual high data usage Non-familiar apps in the app list The fast drain of the battery Long shutdown time Strange interference and sounds during calls Signs of activity during standby mode
If your phone exhibits any of these symptoms you might have a spyware app installed and running on it.
Common spy apps
There are many apps that have been designed to spy on people that can be downloaded in the app store or on Google Play today. Most of these spyware apps are aimed at parents wanting to keep an eye on and protect their children. However, these can be used by anyone in order to spy on a target person via their phone.
Below is a list of common apps that can be used to spy on you. Many spyware apps require a phone to be ‘jailbroken’ or ‘rooted’ before being installed, this is when the phone’s operating system is changed to allow the phone to become unlocked and customizable.
mSpy : An undetectable spying app for iOS devices. It can be used to read your chats, see your location, view your email, check your call history, record your keystrokes, and more.
Spyera : This app requires rooted and jail-broken iPhones to work. It can go undetected and monitors phone calls and your call history. It even allows call recording and eavesdropping on live calls.
Flexispy : Flexispy prides itself as the #1 phone monitor for parents and can monitor everything from calls to social texts.
Umobix : This powerful spyware app has a dashboard that allows users to easily monitor someone’s location, calls, texts, keystrokes, all major social media, and more. You can detect Umobix because it heats up the infected phone and greatly affects the battery life of the infected device.
Ikey Monitor : Although it requires the device to be rooted for Android or jailbroken for iPhones, this spy app captures keystrokes, passwords, and screenshots, allows for call recording and supports multiple languages.
Clevguard : Available for both iOS and Android, Clevguard allows users to track GPS and Wi-Fi locations, capture screenshots remotely, and more. Due to a recent update, the spy app drains the target phone’s battery significantly.
Remove spyware from your phone
If any of the beforementioned apps are present on your phone you need to remove them right away.
Go to your phone settings and remove the malicious applications, then download some protection suite and scan the whole phone for any other trace of software remains or other malware apps.
If you have just installed the latest Cumulative Update on your Windows 10 computer and you find that since then, the Windows 10 Start Search is not displaying any results when you try to use it to search for something in your computer, then this post might help as it will give you some suggestions to fix the problem.
This problem might be caused by some bugs brought in by the new cumulative update you’ve installed. It is also possible that Cortana is having some issues or that the Windows Search service hasn’t been initialized. Whatever the cause is, here are some suggestions you need to follow to fix this issue. You can try running the Search and Indexing troubleshooter or configure the
Run Search and Indexing Troubleshooter
Configure the Windows Firewall
Reinstall Cortana.
Option 1 – Try to run the Search and Indexing troubleshooter
The first thing you can do is to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for Cortana are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter.
Option 2 – Restart Cortana’s process in the Task Manager
Restarting Cortana’s process in the Task Manager could also help you resolve the problem. Refer to the steps given below to do so.
Tap the Ctrl + Alt + Del keys to open the Security options window.
From there, look for the Task Manager in the given list and open it.
Next, look for the process of Cortana and right-click on it, and then select the End Task option to end its process.
After that, the Cortana process will restart by itself and re-initialize.
Option 3 – Try resetting Cortana
Open Cortana and go to the Settings section where you’ll see the “Turning off Cortana clears what Cortana knows on this device, but won’t delete anything from the Notebook. After Cortana is off, you can decide what you’d like to do with anything still stored in the cloud” option. Turn this option off.
Restart your PC.
After your computer boots, launch Cortana again and check.
Option 4 – Try to configure the Windows Firewall
Tap the Win + Fn + Shift (Pause) keys to open Control Panel.
From there, open the Windows Defender Firewall applet and click on the Advanced Settings to open the Windows Firewall with the Advanced Security panel.
Next, click on the Outbound Rules section and look for Cortana and then double click on it to open its Properties.
After that, make sure that the “Allow the connection” is selected although this is the default working setting.
Option 5 – Try to reinstall Cortana
If none of the options given above works, you must consider reinstalling Cortana.
First, right-click on the Taskbar and select the Task Manager.
Next, select File menu > Run new task and type “Powershell” in the field and then select the “Create this task with administrative privileges” option.
Click on OK to open the PowerShell console.
After that, type the following command and hit Enter to execute it:
As you know, every Windows Update is essential for every Windows operating system. They have to be regularly installed, especially since they include various security updates that are important to the system. However, there are times when Windows Update fails to execute properly and you get errors like the error code 0x80070BC9. When you encounter this particular Windows Update error, you will get the following error message on your screen:
“0x80070BC9 – ERROR_FAIL_REBOOT_REQUIRED. The requested operation failed. A system reboot is required to roll back changes made.”
This kind of Windows Update error is most likely caused by a newly installed problematic software, corrupted Windows Update files, or policies that restrict the behavior of the Windows Module Installer. The Windows Module Installer, also known as “WMIW” or “TiWorker.exe”, is the one that checks for new updates from the Windows server and installs them on your computer. This is why you need to make sure that you do not have any policies that control the start behavior of the Windows Module Installer since this service must not be hardened to any start value and should be managed by the operating system.
To resolve the Windows Update error code 0x80070BC9, you can check out the options provided below.
Option 1 – Try checking the status of the Windows Modules Installer Worker Service
Since the Windows Update error code 0x80070BC9 has something to do with the Windows Module Installer Worker service, you need to check its status in the Service Manager. Refer to the following steps to do so.
In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “MSC” in the field and hit Enter to open the Services Manager.
After opening the Services Manager, look for the Windows Modules Installer Worker Service.
Once you found it, check its status and make sure that its Startup type is set to Manual.
Now click on the Start button and see if it fixes the Windows Update error.
Option 2 – Run the Windows Update Troubleshooter
You might want to run a built-in Windows Update troubleshooter to resolve the Windows Update error. It is one of the things you can check out as it is known to automatically resolve any Windows Update errors like error code 0x80072EE2. To run this troubleshooter, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.
Option 3 – Try contacting the IT administrator to modify the group policies
You could also try to contact the IT administrator to have the group policies modified. This option is applicable for company-managed systems. As mentioned, one of the possible causes of the Windows Update error 0x80072EE2 is the policies that control the start behavior of the Windows Module Installer. Thus, you need to have them removed so that the Windows Module Installer Worker service is managed by the operating system itself. And since there could be many policies, it is highly advised that you contact your company’s IT administrator to get the job done for you.
Option 4 – Try to install the Windows Updates in a Clean Boot State
There are some instances that some conflicting programs installed in your computer might be the one that’s causing Windows Update error code 0x80070BC9. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
Log onto your PC as an administrator.
Type in MSConfig in the Start Search to open the System Configuration utility.
From there, go to the General tab and click “Selective startup”.
Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
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.
One of the worst Blue Screen of Death errors you can encounter is the UNMOUNTABLE_BOOT_VOLUME BSOD on Windows 10. In this BSOD error, your computer won’t be able to properly boot. Meaning to say, even if you want to reinstall Windows, you won’t be able to back up your important files. Thus, it wouldn’t be really feasible to fix the system files, and besides, reinstalling Windows 10 would take a lot of time, not to mention resources.
The UNMOUNTABLE BOOT VOLUME error is the kind of BSOD error that occurs if Windows is not able to access the volume that contains the boot files. Resolving this BSOD error won’t be easy but you will surely manage by following the suggestions laid out below but before you go on, make sure to create a System Restore Point.
Option 1 – Try checking the hardware
If you got the UNMOUNTABLE BOOT VOLUME BSOD error while trying to update your computer to a higher version of Windows, then you need to check if you have the compatible drivers for the disk controller as well as re-check the drive cabling and make sure that it is properly configured. And if you’re reusing either ATA-100 or ATA-66 drivers, ensure that you have an 80-connector cable and not the standard 40-connector IDE cable.
Option 2 – Try using Automatic Repair
You might also want to use Automatic Repair in fixing the BSOD error. 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 in 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.
Option 3 – Try fixing the Master Boot Record or MBR
The MBR or Master Boot Record is the location and is where the architecture of the operating system is installed. Thus, if either the location or the architecture has tampered with, it can cause lots of BSOD errors like the UNMOUNTABLE BOOT VOLUME error.
Boot your computer into Safe mode with Networking using the Advanced startup options which you can access by tapping the F2 or F8 key. Once you’ve accessed the Advanced startup options.
After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
After opening Command Prompt, execute the following command and hit Enter:
bootrec /fixboot
After entering the command, wait until the process is completed and then restart your computer to apply the changes made successfully.
Option 4 – Run the CHKDSK command to repair hard disk errors
Running the Chkdsk utility could help you fix the UNMOUNTABLE BOOT VOLUME 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.
After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
After opening Command Prompt, execute the following command and hit Enter:
chkdsk /f /r
The command you entered will scan the hard disk for any errors and will automatically fix it if it finds some issues. Wait for the process to be completed and then reboot your PC.
Cache files are temporary files that have been created by various applications and services when used. As temporary files, they are safe to be removed and deleted from the system since the application or service will create new ones when needed but sadly will not remove old ones, this task is left to OS itself.
Automatic Windows cleanups can mostly take care of these things but for top-notch performance clearing cache manually is a far better option. We will here explore various cache temporary files, where they are, and how to clean them. Sit back and let’s do some cleaning!
Clear cache using Disk Cleanup
Open Start menu and search Disk Cleanup
Click on it in search results
Click on the drives drop-down menu and select the drive where is Windows 11 installed
In the Files to Delete section enable all boxes and click on OK
Click on delete Files to confirm
Clear Microsoft store cache
Press ⊞ WINDOWS + R to open the run dialog
Type in WSReset.exe and press ENTER
Black blank windows will appear, wait for the window to close itself and you are done
Trojan.Kryptik creates the following registry entry or registry entries:
