Virtual Reality is slowly becoming standard in gaming. More and more affordable headsets are coming out lowering entry prices and making them affordable for all. But in a sea of new VR headsets, it is important to at least purchase a decent one that will perform nicely and hopefully last longer. Therefore in today’s article, we will address some of the best options currently available on the market,

Oculus Quest 2

With its Rift model, Oculus set itself as a big player in VR. Now the company is slowly bowing out of the dedicated, tethered VR headset with its latest Quest 2 designed to primarily be a standalone headset. In case you do not know, tethered headset means that the headset itself is connected to your PC and is using its power to drive your VR experience. Now technical specifications of Quest 2 are pretty OK and it can drive stuff pretty decently and if you want you can purchase the dedicated cable to connect it to your PC for the full experience of games requiring more capable hardware. Oculus Quest 2 is the cheapest headset on this list and with its stable performance, is highly recommended.

Valve Index VR

Although the headset itself is nothing revolutionary or special its controllers are. They can track individual finger movements, making games (that take advantage of them) much more immersive than the standard trigger grips on other controllers. The Index's higher refresh rate makes for smoother action, as well, which is another nice bonus. If you already have an HTC Vive or Vive Cosmos Elite, and their base stations (not the regular Cosmos), you can buy only the controllers.

Sony PlayStation VR

The PlayStation VR is compelling thanks to Sony backing its development, plus the PlayStation 4's affordability and availability compared with gaming PCs. All you need is the headset, a PlayStation 4, and a PlayStation Camera (now included with most PlayStation VR bundles). Not really the best of the bunch but still one of the top ones for console gaming. Sony is working on a new PlayStation VR system for the PlayStation 5, with redesigned controllers. The new headset hasn't been revealed yet, but the company has released a preview of the new controllers.

HP Reverb G2 VR

HP headset is one which you get if you want the best image quality in VR headset, sadly controllers did not follow the same quality of headset itself. But this is still a pretty decent headset overall and worth the purchase.

HTC Vive Cosmos

HTC's Vive Cosmos is the upgraded version of the Vive. It features a higher resolution and replaces the external base stations with outward-facing cameras for motion tracking. It's a comprehensive package for whole-room VR. HTC recently released the Vive Pro 2, a high-end VR headset targeting both enterprise users and consumers. This new headset features a 2,448-by-2,448 resolution display for each eye, making it the highest-resolution headset currently available. It's also more expensive than the Cosmos Elite. Sadly one thing that is bringing this headset down is the price.

Shortcut virus is an easily spreadable and annoying combination of Worm and Trojan that hides all of your files and folders and then replaces them with shortcuts that look identical to replaced files and folders. Once disguised it will wait patiently for a user's click and once that happens it will replicate itself and further infect the system. This rapid spread can lead to stolen personal data, some system hick-ups, and other system-related issues. This malware mainly affects physical file transfer devices like for example and most USB drives, hard drives, and SD memory cards and it can easily transfer itself to the computer. The advantage of this shortcut virus comparing it to others is that it is mostly undetected by a vast variety of antivirus software. So running just anti-virus software maybe not be enough to remove it from your system. Luckily for all unfortunate users that have caught this annoyance, it can be easily removed fully manually in a short time.

How to Remove Virus from USB and other removable media

Firstly plugin USB, SD, or removable drive. The infection will transfer to your computer when the infected drive is plugged in so before we go to clean the computer itself, clean each removable drive that you have. Also know that infection will spread from computers into removable devices as well if it is not cleaned. Open the File Explorer and remember under which letter is removable drive registered. Open Command prompt but with administrator privileges and go to infected rive by typing its letter followed with “:” (for example D:) and press ENTER Once you have successfully gone to infected drive type in command prompt: Attrib -s -r -h /s /d *.* This will unlock all original files back into removable storage, next copy all files to your computer, and format the removable drive. Once the format is complete, unplug the removable device. Continue to clean all devices with the same method.

How to Permanently Remove a Shortcut Virus from Your PC

Now once we have cleaned all removable devices it is time to fully clean the PC Firstly open the task manager ( CTRL + SHIFT + ESC ), in the process tab find wscript.exe or wscript.vbs, right-click on it (or both if present), and select End Task. Now close the task manager and press Start. Inside start typing in registry editor to search for it and once found open it. Find the following key inside the registry editor: HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run In the right panel, look for any strange-looking key names, such as odwcamszas, WXCKYz, OUzzckky, etc. For each one, run a Google search to see if it's related to shortcut viruses. If any returns a positive match, right-click on them and select Delete. !!! Accidentally deleting an important key can cause Windows to become unstable, so double-check everything !!!. Close the Registry Editor Now press ⊞ WINDOWS + R to open the run dialog and type in it Msconfig followed by ENTER. Once the System Configuration window opens go to the Startup tab. In the Startup tab, look for any strange-looking .EXE or .VBS programs, select each one and click Disable. Close the Window. Once again open the run dialog and type inside %TEMP% and press ENTER in order to open the Windows temp folder. Inside this folder delete everything. Next in the File explorer go to C:\Users\[username]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup Look for any strange-looking .EXE or .VBS files and delete them.

Internal Error 2771 - What is it?

Internal Error 2771 is an internal error code associated with Kaspersky Internet Security and Antivirus software. This error pops up when Kaspersky Internet Security software fails to install on your PC successfully. Installation of the software is interrupted and therefore it ends prematurely. This happens mostly when you try to install a new build on an existing installation. Internal Error 2771 is displayed in one of the following formats:

Internal Error 2771, Sandbox Feature or Internal Error 2771, WholeProduct Feature

Solution

Error Causes

This error may result on your computer screen due to several reasons. Some of the most common underlying causes include:

• A leftover Registry Key
• Bad entries from previous Security Package
• INFCACHE.1 file corrupted
• Conflicts with other security software installed on your system

Further Information and Manual Repair

To successfully overcome this problem and ensure the successful installation of Kaspersky Internet Security software on your system, try the methods given below.

Method 1- Remove the Leftover Registry Key

Sometimes Internal error code 2771 may appear during installation due to the leftover registry key from the previous Kaspersky software removal. A registry key is often created when uninstalling the previous Kaspersky version from the PC. This key is left behind even after you reboot your system. This key is called AVP**_post_ uninstall, you need to delete it to ensure the new version of the Kaspersky program is installed successfully on your PC.  For this, simply go to the start menu and type Regedit in the search bar. Now navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun and then look here for the registry key called AVP**_post_ uninstall.

As you know, Windows 10 is equipped with a Mobile Hotspot feature that allows users to share the existing internet connections to other devices over Wi-Fi. However, one of the downsides to this feature is that it does not stay on if there are no devices connected to it for over five minutes. In other words, if there are no devices connected to the mobile hotspot for five minutes, it will turn off automatically. Thus, if you want the mobile hotspot to stay turned on, then you’ve come to the right place as this post will walk you through how to stop the Mobile Hotspot from turning off in Windows 10. There are two scenarios tackled in this post wherein the Mobile Hotspot feature turns off automatically and where the hotspot disables when there is no internet connection. To remedy these scenarios, you can try turning off the power saving feature or use a PowerShell command to change the “PeerlessTimeoutEnabled” settings or increase the Mobile Hotspot idle timeout settings. You could also increase the timeout period when a cellular connection is not available or disable the Wi-Fi and network adapter power management options. For detailed instructions, refer to each one of the given options below.

Option 1 – Try turning off the power saving feature

The first solution you can check out is to turn off the power-saving feature. To do so, follow these steps:

• Open the Settings app and go to Network & Internet and from there, click on the Mobile Hotspot option.
• Next, toggle the “Share my Internet connection with other devices” option.
• After that, toggle the “When no devices are connected, automatically turn off mobile hotspot” option.

Option 2 – Execute a command in PowerShell

The next option you can try to keep the mobile hotspot turned on is through a command in PowerShell. To get started, follow these steps:

• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option.
• Next, execute the following command to make sure that the Mobile Hotspot stays on even when no devices are connected to it:

powershell -windowstyle hidden -command "Start-Process cmd -ArgumentList '/s,/c,net stop "icssvc" & REG ADD "HKLMSYSTEMCurrentControlSetServicesicssvcSettings" /V PeerlessTimeoutEnabled /T REG_DWORD /D 0 /F & net start "icssvc"' -Verb runAs"

• After the command is executed, here is what the script is doing in the background:
  • It stops the Mobile Hotspot service (icssvc).
  • It navigates to this registry path (HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesicssvcSettings) and creates a DWORD key named “PeerlessTimeoutEnabled” which has a value of 0.

• It then restarts the Mobile Hotspot Service (icssvc).

Option 3 – Try increasing the Mobile Hotspot idle timeout settings

Another option you can try is to increase the idle timeout settings of the mobile hotspot. In case you don’t know, the default timeout when there’s no active connection is about five minutes. So if you don’t want to keep it on always but want to keep it on longer than five minutes, then this option is for you. All you have to do is change the same key (PeerlessTimeout) as mentioned above, at a different location. In fact, you can change it to a maximum of 120 minutes. To give this a try, follow these steps:

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSystemControlSet001ServicesICSSVCSettingsPeerlessTimeout
• From there, change its value to anywhere between 1 up to 120.
• Once done, exit the Registry Editor and restart your computer.

Option 4 – Try increasing the timeout period when a cellular connection is not available

There are many times when you want to connect devices so it becomes part of the network. And as pointed out, the Mobile Hotspot turns off automatically when there is no internet or mobile data but when you use a registry setting, you can change any value between 1 and 60 inclusive.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSystemControlSet001ServicesICSSVCSettingsPublicConnectionTimeout
• From there, set the value of the “Timeout” key between 1 and 60.
• After that, close the Registry Editor and restart your PC.

Option 5 – Try to disable the Wi-Fi and Network adapter in Power Management options

As you know, the Wi-Fi adapter and the network devices have properties that will turn off when on battery and when it’s not used for a long time so you can try to disable these options.

• Tap the Win + X + M keys to open the Device Manager.
• Next, expand the list of Network devices and select the Wi-Fi adapter.
• After that, go to the Power Management tab and make sure that anything related to power saving should be turned off. This will ensure that none of the network devices will turn off the Mobile Hotspot or trigger anything that will do that.

One of the worst problems users can encounter on their computers is Blue Screen of Death errors as some of them are quite hard to fix. One of them is the “The driver detected a controller error” Blue Screen error. It could be followed by “DeviceIdeIdeport0 OR”, “on deviceharddisk0dr0”, or “DR3” or the name of the drive or port that’s causing the problem. If you are one of the users who encountered this error, then the suggestions provided in this post would definitely help you in fixing the problem.

Option 1 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem.

• After that, right-click on each entry of the device drivers and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 3 – Try to update the BIOS

Updating the BIOS can help you fix the ATTEMPTED_WRITE_TO_READONLY_MEMORY BSOD error but as you know, 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.

Option 6 – Replace your motherboard

If your computer is still under warranty, you should consider replacing your computer’s motherboard in case the options given above failed to work in fixing the Blue Screen error.

As you know, the Windows 10 operating system has support for a dedicated high-end graphics processor that brings in capabilities inside to support Graphics Cards from NVIDIA or AMD. This helps the operating system to function in a much better way by segregating the graphics-intensive operations from the CPU to a dedicated processor. However, there are times when it also experiences some issues that lead to some errors like the “Failed to create a graphics device” error. It is possible that your computer has more than one screen or graphics card which is why you’re getting this error. To fix it, you need to try reinstalling DirectX or reinstall the Graphics Card driver. You could also try to manually check the hardware or power cycle of your computer. To start troubleshooting the “Failed to create a graphics device” error, follow the given suggestions below.

Option 1 – Try running the DirectX Diagnostic Tool

Since the error has something to do with the DirectX Graphics APIs, you can run the DirectX Diagnostic tool to resolve the problem.

Option 2 – Try updating or re-installing DirectX

If the DirectX Diagnostic tool didn’t work, you can try to update or reinstall DirectX instead. This can help in fixing the problem because when you reinstall or update DirectX, it will replace the incompatible or corrupted components of DirectX from your computer.

Option 3 – Update or reinstall the Graphics card drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in MSC into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 4 – Try to physically check the hardware of your computer

You might also want to check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Graphics Card of the computer. In doing so, you have to use a small blower or you could also use a soft cloth and run the components gently. Make sure that you don’t damage any parts with moisture or cause harm to any circuits while you carry out this task.

Option 5 – Try to power cycle your computer

You could also try to power cycle your computer to fix the error. To do that, you have to turn off your computer in a way that the power is completely cut off and all the fresh configurations of files are loaded when your computer is booted up. The first thing you have to do is to shut down your computer and if you are using a laptop with a removable battery, you must remove the battery for a couple of minutes before you plug it back in and boot your laptop. On the other hand, if you are using a desktop computer, press and hold the power button until the CPU goes off and take out the power cable for a minute or so and then plug it back in. Boot your computer and see if the error has been resolved.
