Malware Guide: How to Remove BitCoinMiner

Recently, several Windows 10 users have reported an issue with the Windows folder sizes in their PCs. If you are one of these affected users, read on as this post will walk you through fixing this issue. For instance, if you have a folder with 100 GB worth of data and when checking its size using its properties, you see the wrong size instead of 100GB. The size displayed will most likely be a random number which can either be bigger or smaller than the real size of the folder. This incorrect folder size issue does not happen to any specific drive or certain kinds of folders as any folder can be affected by this incorrect folder size issue. When you try to rename the affected folder, the size will change but its size still remains to be incorrect. The root cause of this particular issue is in Windows 10 itself. It is a known bug that came along with one of the latest Windows Updates which prevents the File Explorer to accurately read the metadata of a certain folder or file and leads to displaying incorrect and unexpected file sizes and the reason why you might also notice that your drive is also not correct. Since this is brought upon by one of the recent or latest Windows Updates the good thing is that Microsoft will most likely release a fix on its next upcoming updates but until then, you will be left with no choice but to deal with an incorrect folder or file size. To remedy that, here are some suggestions you can try that might fix the problem.

Option 1 – Try using the System File Checker

The 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 to good system files that might be causing the incorrect folder or file size in Windows 10. 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.

Option 2 – Try resetting Windows 10

To fix the folder and file size issue, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files. That way, you won’t have to deal with inaccurate folders or file sizes as you browse and use your files.

Option 3 – Wait for the Windows Update

As mentioned, this is already a known issue and a lot of Windows 10 users have already complained about it to Microsoft so a bug fix will be soon released in the latest Windows Updates.

PrintNightmare vulnerability has been a struggling issue for Microsoft in the past weeks, each time it seems to be addressed and fixed something new popped up and it still had issues. Microsoft finally addressed the issue but with a price. The default behavior of Point and Print is changed. From this fix onward, the Point and Print driver installation and update behavior will require administrator privileges, which should prevent the exploit to the Windows Print Spooler that could be used by malicious individuals to gain administrative privileges in Windows. The drawback of this fix from Microsoft is that non-elevated users may have difficulty adding or updating printers. Microsoft feels that the security risks caused by PrintNightmare are worth the tradeoff, though. If you really want to let non-elevated users add printers, you can follow the instructions in this Microsoft Support article to disable this mitigation with a registry key. However, doing so will expose you to this known vulnerability and isn’t recommend.

As you know, one of the basic apps in the Windows 10 operating system is the calculator and it can even be extended to a scientific calculator which makes it really useful for users. However, there are instances when you might encounter some issues while using this app. One of the issues about the Calculator app that’s been reported recently is that the Calculator app is not working. If you encounter the same problem, then you’ve come to the right place as this post will guide you on what you can do to fix the problem. Based on the reports, users claimed that the issue with the Calculator app occurred right after they’ve installed a feature update, while other users claimed that the Calculator app never really worked on their computers and there are also cases where the app opens but it either freezes or crashes. According to researchers, the main causes of the problem include a feature update that could’ve altered the settings. It could also be due to problems with the login account or corrupted and missing files, or the problem could also with the calculate app itself. To resolve this problem, here are some suggestions you can follow.

Option 1 – Run 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 to good system files that might be the reason why the calculator app is not working properly. 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 computer.

Option 2 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” that could help in fixing the Calculator app.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism (.)exe /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 3 – Try logging into your computer using a different User Account

You might want to try logging into a different User Account since it is possible that the issue could have something to do with your log-in account. Thus, you can isolate this possibility by logging into a different user account. If you don’t have any other user account, simply create a new one by clicking on the Start icon and then go to Settings > Account > Family & other users. From there, go to the Other user's section and click on the Add someone else to this PC option, and then inputs all the needed information and restarts your computer. Once your computer has restarted, log into your computer using the newly created user account.

Option 4 – Try to reset or reinstall the Calculator app

If the first three given options didn’t work, you might want to reset or reinstall the Calculator app. To do that, follow these steps:

• Click on the Start button and go to Settings > Apps > Apps and features.
• Next, look for the Calculator app from the app list and click on it to see its other options.
• After that, select the Advanced options and go to the Reset section and then click on the Reset button to reset the Calculator app.

Note: You also have the option to reinstall the Calculator app. All you have the option to visit Microsoft Store and from there, uninstall the Calculator app.

When you try to open a website but instead encounter an “Access Denied, You don’t have permission to access on this server” error message along with the ULR which you aren’t able to access with a reference number, then it is most likely caused by some network-related issue in your browser. Note that this error mostly occurs on Firefox browsers. The “Access Denied” error appears when your Mozilla Firefox browser uses a different proxy setting or VPN instead of what’s really set on your Windows 10 PC. Thus, when a website detected that there is something wrong with your browser cookies or your network, it blocks you which is why you can’t open it. To resolve this error, here are some suggestions you can try. And if you got the same error message on a different browser, you can still follow the possible solutions given below.

Option 1 – Try clearing everything about the website

• Open your browser and tap the Ctrl + H keys on your keyboard.
• After that, look for the listing of the website from your browser history and right-click on it.
• Then select the “Forget about this site” option. This will get rid of all the data such as browsing history, cache, cookies, and passwords. Thus, if you have a password saved or other important data of the website, you have to save it first before you tap the Ctrl + H keys.

Option 2 – Try disabling the VPN

As pointed out earlier, if you are using VPN, this could be the reason why you’re getting the “Access Denied” error so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there.

Option 3 – Uninstall the VPN service you are using or use a different provider

If you disabling the VPN service worked in fixing the “Access Denied” error, you might want to uninstall it. As mentioned, website administrator blocks IP ranges if they notice any malicious activities and because of this, your IP address might fall into the banned range even if you didn’t do anything at all. To uninstall the VPN service, follow the steps below.

• Tap the Win + R keys to open the Run dialog box
• Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
• From there, look for the VPN service you are using, select it and then click on Uninstall to remove it.
• After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.

Option 4 – Try disabling the proxy server for your LAN

If your PC was just attacked by some adware or malware as of late, it is possible that it has changed the network settings in the system and might display spam advertisements. Thus, you have to disable the proxy server for your LAN. To do that, refer to these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

HIDCLASS.SYS is a Windows operating system driver file. HID or Human Interface Device includes Keyboards, mice, and other input devices. HIDCLASS.SYS is a critical system driver file that is responsible for connecting different kinds of devices all over the system, including the functionality where a Word Processor can access the printer to print documents. This file comes under the category of kernel-mode device drivers and if the driver fails, it can result in a Stop Error. There are a lot of Stop errors related to the HIDCLASS.SYS file, such as:

• KMODE EXCEPTION NOT HANDLED
• SYSTEM SERVICE EXCEPTION
• DRIVER POWER STATE FAILURE
• PAGE FAULT IN A NONPAGED AREA
• SYSTEM THREAD EXCEPTION NOT HANDLED
• DRIVER VERIFIER IOMANAGER VIOLATION
• IRQL NOT LESS EQUAL

The fixes for the Blue Screen errors related to the HIDCLASS.SYS files are pretty simple but before you troubleshoot the problem using these fixes, make sure that you boot your computer into Safe Mode with Networking first. After that, get started on these tips:

Option 1 – Update or rollback or disable concerned device drivers

To fix the HIDCLASS.SYS error, you can also try to roll back, or update, or disable the concerned device drivers.

There are many times when you have to change the ownership of a folder or a file so that other users can use them as well or if you want to transfer files to them, or an old account has been removed and all the files need to be assigned to a new user. Windows 10 keeps all these files locked under the account by default which created a folder or file. So unless a user is an admin or if the file belongs to that particular user, other users won’t be able to access or edit the file. So if you want to change the ownership of a folder or a file, then you’ve come to the right place as this post will guide you on how exactly you can do that.

To get started, make sure to follow the instructions provided below carefully.

Step 1: First, you need to open File Explorer by tapping the Win + E keys. Once you’ve opened it, navigate to the folder or file that you want to change the ownership. Step 2: Right-click on the folder or file and click on Properties and then go to the Security tab. Step 3: From there, click on the Advanced button located at the bottom right part of the window to open the Advanced Security Settings of the folder or file. Step 4: As you can see, the current owner will be listed with the Change link available next to the “Owner” label. Now click on this link to open the Select User or Group window. Step 5: After that, click on the Advanced button once again and click on the “Find Now” button to see the list of all the users as well as groups that are available in the computer. Step 6: Then select the user you want to give ownership to and click on the OK button and then click the OK button once more to save the changes made. Step 7: This will take you back to the Advanced Security Settings window but this time, the owner will be changed to whoever user you’ve selected. But you’re not done yet as you still have to check two additional options to help you completely transfer the ownership of the sub-folders as well as the files. You have to check the checkbox of the following options:

• Replace owner on sub-containers and objects
• Replace all child permission entries with inheritable permission entries from the object.

Step 8: After that, you need to click the Apply and OK buttons to confirm and save the changes made. This will completely transfer the ownership of the file. However, there is still one last thing you have to do – you have to go back to the Advanced Security Settings window to remove the access of any other user on the folder or file. Once you’re there, remove the existing user to make sure that the only assigned user has the access to the folder or file.
