SmartScreen is a cloud-based anti-phishing and anti-malware component that’s come packed in all Windows 8 (8.1) and Windows 10 versions. This security component is also used in several browsers and programs like Internet Explorer, Microsoft Edge and Outlook.com. Although this program is quite useful, there’ve been reports that SmartScreen is apparently blocking Microsoft’s own apps from opening. According to some users, they only get the “Windows SmartScreen can’t be reached right now” error message every time they try to open apps from the built-in Windows suite like Photos, Mail, Alarms, Maps, etc. Whenever Windows SmartScreen is either down or unreachable on an end-user PC, your computer won’t be able to download anything in both official and unofficial channels. This error might be due to a corrupted Windows account, or it could be that SmartScreen is disabled from the Windows Defender Security Center or it might be down due to an MS issue. In addition, the error might also be caused by a proxy entry.

Option 1 – Make sure that SmartScreen is enabled

Before anything else, the first thing you must do is to check if SmartScreen is even enabled as it might be the reason why you’re getting the error. You can verify this by simply going to the Windows Defender Security Center. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “ms-settings:windowsdefender” in the field and hit Enter to open the Windows Defender Security Center.
• After that, click on the Open Windows Defender Security Center button located under Windows Security.
• Then click on App & browser control.
• From there, make sure that the Check apps and files toggle is set to Warn and then check the same thing for Microsoft Edge and SmartScreen for Microsoft Store apps.
• If it turns out that SmartScreen is indeed disabled, you have to restart your computer after making some changes and then check if the issue is fixed upon the next startup.

Option 2 – Check if SmartScreen is down for maintenance

Another possible reason why SmartScreen is not working is that it might be scheduled for maintenance. When SmartScreen is scheduled for maintenance, it will become unreachable for a lot of users at the same time and so before you go over unnecessary troubleshooting steps, you need to verify if SmartScreen is down for maintenance or not.

Option 3 – Try to disable the proxy server

If applicable, you can try to disable the proxy server to fix SmartScreen. There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. In some instances, certain proxy servers can interfere with the SmartScreen component and cause it to become unusable. However, if you are not using a proxy server, just skip this option and proceed to the next one, otherwise, follow the steps below to disable the proxy server.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “ms-settings:network-proxy” in the field and hit Enter to open the Proxy tab under Settings.
• After that, scroll down to the Manual proxy setup and make sure that the toggle button of the “Use a proxy server” option is turned off.
• Now restart your PC and check if the problem is fixed upon the next startup.

Option 4 – Try to create a new Windows user account

There are some users who were able to fix the problem by simply creating a new Windows user account. Although this solution will make you lose a couple of settings enforced through your user account, it’s actually effective in circumventing the “Windows SmartScreen can’t be reached right now” error. To create a new Windows user account, here’s what you have to do:

• Tap the Win + R keys to open the Run dialog box.
• And then type “ms-settings:otherusers” in the field and hit Enter to open the Family & other people tab under the Accounts menu.
• After that, click on the “Add someone else to this PC” option and then click on “I don’t have this person’s sign-in information.
• Next, insert the user credentials like emails, password, birth date, etc., and then click Next. Take note that if you want to create a new local user account, just click on Add a user without a Microsoft account.
• After you’re done creating the new Windows user account, click the start icon and then click the account icon and choose to Sign out.
• After you’re logged in, check if SmartScreen now works properly or not.

OneXPlayer is a direct competitor to Valve’s upcoming steam deck. This device is clearly inspired by Valve’s offering and it shows all over the place, from its looks to its purpose and aims to PC gamers as a handheld device.

Hardware under the hood

This device is packing a 7-inch 1080p display, 11th generation Intel Core i7-1195G7 CPU, stunning 16GB of RAM, 512GB SSD drive with the option to purchase 1TB or 2TB model. GPU of choice is Intel iris Xe Graphics that is in our opinion a bottleneck in the whole system and for more demanding games, we believe switching them to 720p would be a better option. Everything here is powered with a 10455 mAh lithium-ion battery.

OneXPlayer inputs and other stuff

Handheld is equipped with dual bumpers and dual linear triggers. The console comes with dual speakers on both sides of it. Inside the console, there is an aluminum heat sink with copper heat pipes and a fan in order to cool internal hardware. On the outside, we have two USB-C ports and one USB-A port for connections, and of course, a headphone jack for headphones. The console comes with Wi-Fi 6 and Bluetooth 5.0 for wireless connectivity.

Price

The base entry model will cost you a whopping $1.259, 1TB model $1.399 and 2TB one will go as far as $1,599. With this kind of price, I am not sure it can come up as a winner against Valve. Sure it is packing fully licensed Windows 11 that will for sure offer more options than Stem’s OS based on Linux but even with that advantage I do not think it justifies such a big price difference.

Conclusion

Of course, this kind of console or handheld PC will still find its customer base, many users will probably like it since it comes Windows ready out of the box. Sure, you can place Windows on Steam deck as well but you will need to know how, where everything is ready and you can run beside steam other launchers without issues like origin, uplay, gog, etc. How this will be accepted by community time will tell but it is good to see that there is variety and competition in handheld PC space.

It seems that last few days we were riding some Razer bandwagon but rest assured that we are not sponsored by them in any way, truth is that simply they come up with some interesting accessories which I believe are worth covering. Gaming Chair itself comes in two colors, fully black and green black combination and it is not really an entry-level chair if we are talking about price. The chair itself is around 600USD depending on the distributor and considering that price range it is placed in more top cream of gaming chairs but it is worth every dime.

Iskur Specifications

Iskur is made of a steel frame with a reinforced plywood lumbar support frame for added weight tolerance. Frame and lumbar support are surrounded with memory foam and all of that is wrapped in cotton and polyester layer which is again wrapped in multi-layer synthetic leather making the chair very durable for long hours of daily use. The chair also comes with a memory foam head cushion which is detachable and removable if you do not wish to use it. On the Razer website among specifications, it stands that the chair is best suited for persons from 5’6” – 6’2” (170 – 190cm) height and up to 299lbs (136kg).

Features

The chair has, of course, height adjustment as any gaming chair and surprisingly it has great control for the armrest. The armrest can be adjusted in 4 different ways: up & down, left & right, forward & backward, and inward & outward. The backrest can be also tilted up to 26 degrees angle. All of these features are great and good but there is one more feature that really makes this chair stand out from rest and it is Lumbar support. Iskur has an adjustable lumbar support system on the lower part of the backrest. With your lumbar support secured, you can then make the necessary tweaks to optimize the rest of your posture using the Razer Iskur’s adjustable height, backrest, and armrests.

Conclusion

Razer Iskur is neither cheapest nor perhaps the best gaming chair you can buy, but it is a really good one. It is well manufactured and made to feel and look like a premium product that actually it is.

If you notice that your tabs in your Firefox browser keep on crashing recently, then there might be something wrong with your browser. Every time any of your tabs crashes, you might encounter an error message saying, “Gah, Your tab just crashed”. If you encounter this kind of error message then it is most likely that your Firefox Profile is having some issues with the existing installation of Firefox. The “Gah, Your tab just crashed” error rarely happens but when it does, it can get quite annoying as you won’t get to browse the internet peacefully. So to fix it, here are some suggestions you could check out.

Option 1 – Try disabling multi-process tabs in Firefox

Since Mozilla has one process for Firefox itself, while one process handles all the tabs, you have the option to disable these multi-process tabs in Firefox. To do that, follow these steps:

• In the address bar of Firefox, type “about: config” and hit Enter.
• Next, look for the following configurations and set them to false.
  • tabs.remote.autostart = false
  • tabs.remote.autostart.2 = false
• After that, double-click on the toggle switch between true and false.

Option 2 – Try checking your Add-ons

In this option, you need to start Firefox in Safe Mode and then check if the problem is fixed. If it is, you may have to check your Firefox add-ons as well as extensions as one of them might be the one that's causing the “Gah, Your tab just crashed” error.

Option 3 – Downgrade the Firefox version you’re using

It could be that the current version of Firefox you’re using has some issues so you might have to downgrade it, especially if you are already using the latest version. To downgrade your Firefox browser, go to the directory of the other versions and languages and select an older version that worked for you. After that, you have to disable automatic Firefox updates.

• First, click the menu button and select Preferences.
• Next, go to the Firefox Updates section under the General panel.
• Then select the radio button labeled “Check for updates but let you choose to install them”. This will ensure that you will not have the same issue with the new update.

Note that this is only a temporary fix since updating your programs, including browsers.

Option 4 – Try sending Crash Reports

You might want to send crash reports to Mozilla. This way, Mozilla might come up with some fix to resolve the problem. All you have to do is type “about: crashes” in the address bar. This will list all the crash reports. Now send it to Mozilla using the built-in interface. Although this won’t instantly fix the problem, a lot of user finds it useful. And besides, the issue will get fixed in future releases or with minor updates.

USB Kill, a USB device is able to fry and damage your computer, mobile phone, router, etc. This device is quite dangerous and can kill electronics the moment it is inserted into an available port. By now people should know that they should not put unknown USB sticks into their devices because of potential virus and malware threats but this raises using unknown sticks to a whole new level.

Kill kits are not really new to the market, they have existed before but lately, technology really progressed and the latest USB sticks are really good, their success rate is around 95% which is pretty high and should not be taken lightly.

The second thing that you really should not play with strange USB sticks is that they dropped in price really hard, although top Kill kits will still go as high as around 300 USD, there are really cheap ones lurking in Ali Express that are just 6 USD!!! that makes them affordable devices for the mass market.

The device is made to take energy and current from the port it is plugged in, multiply it and release its charge back into the device, successfully frying some components immediately. Some more professional Kill sticks can even fry devices even when the device itself is not powered and can be even started remotely.

The point of this article is to make you aware that you should not in any kind of circumstances use and plug-in USB sticks into your devices that you do not know where they come from, especially from the mail!!

Option 2 – Try installing or updating the USB RNDIS adapter

RNDIS or Remote Network Driver Interface Specification can also help you resolve the USB tethering problem.

Gaming Wonderland is a Browser Extension for Google Chrome developed by Mindspark. This extension allows you to look up some popular browser games, as well as to find multiplayer games. When installed it changes your default search provider and your default home page to MyWebSearch. While browsing the internet, this extension will gather your browsing information, website visits, clicks, and other information that is later sent to Mindspark ad servers and used to better target ads.

While using this extension you will see additional unwanted ads appearing throughout your browser sessions.

Due to the nature of this application and the fact that it has been marked as a Browser Hijacker by several anti-virus scanners, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijacking means that a malicious code has power over and modified the settings of your internet browser, without your consent. They are made to disrupt browser functions for a variety of reasons. These are generally used to force visitors to a specific site, manipulating web traffic to generate ad revenue. It may appear harmless, but the majority of such sites are not legitimate and will present a serious risk to your online safety. As soon as the program attacks your computer or laptop, it begins to mess things up a whole that slows your system down to a crawl. In the worse case, you could be pushed to tackle serious malware threats as well.

Browser hijacking symptoms

When your web browser is hijacked, the following could happen: you find unauthorized modifications to your web browser’s home-page; new bookmarks pointing to pornographic websites have been added to your bookmarks; default web engine is changed; you are finding browser toolbars you haven’t noticed before; unstoppable flurries of popup advertisements show up on your PC screen; your browser gets slow, buggy, crashes quite often; you’re prohibited access to specific websites, including the site of an anti-malware software firm like SafeBytes.

How does a browser hijacker infect a PC

Browser hijackers might use drive-by downloads or file-sharing websites or even an e-mail attachment in order to reach a targeted computer. They could also be deployed through the installation of a web browser toolbar, add-on, or extension. A browser hijacker can also be installed as a part of freeware, shareware, demoware, and pirated programs. A good example of a notorious browser hijacker is the latest Chinese malicious software called “Fireball”, which has attacked 250 million PCs worldwide. It works as a hijacker but can be turned into a fully functioning malware downloader later on. Browser hijackers will affect the user’s browsing experience severely, keep track of the websites visited by users and steal private information, cause problems in connecting to the net, and eventually create stability issues, making applications and computers freeze.

Browser Hijacker Malware – Removal

Some kinds of browser hijackers can be removed from your computer by deleting malicious software applications or any other recently added shareware. At times, it can be a tough task to discover and get rid of the malicious component since the associated file might be running as part of the operating system process. Novice PC users should not try for the manual form of removal, since it calls for thorough computer knowledge to do fixes on the system registry and HOSTS file. Installing and running antivirus applications on the affected system will automatically erase browser hijackers and also other unwanted applications. Safebytes Anti-Malware incorporates a cutting-edge anti-malware engine that will help you prevent browser hijacker infection in the first place, and clean up any existing problems. Use a system optimizer together with your antivirus software to fix various registry problems, remove system vulnerabilities, and boost your computer's overall performance.

Help! Malware Blocking Antivirus Installation And Access To The Web

Viruses can cause plenty of damage to your PC. Some malware variants alter internet browser settings by adding a proxy server or change the PC’s DNS settings. In such cases, you will be unable to visit certain or all websites, and therefore not able to download or install the required security software to eliminate the malware. So what you should do if malware keeps you from downloading or installing Safebytes Anti-Malware? There are a few actions you can take to circumvent this issue.

Use Safe Mode to resolve the issue

In Safe Mode, you may change Windows settings, uninstall or install some programs, and remove hard-to-delete viruses and malware. In case the virus is set to load immediately when the PC starts, shifting into this mode may well prevent it from doing so. To boot into Safe Mode, press the “F8” key on the keyboard right before the Windows logo screen appears; Or right after normal Windows boot up, run MSCONFIG, look over Safe Boot under Boot tab, and then click Apply. Once you’re in safe mode, you can try to install your antivirus program without the hindrance of malicious software. At this point, you can actually run the antivirus scan to get rid of viruses and malware without any interference from another malicious application.

Switch to an alternate internet browser

Some viruses might target vulnerabilities of a specific browser that obstruct the downloading process. If you seem to have a trojan attached to Internet Explorer, then switch to an alternate browser with built-in security features, such as Firefox or Chrome, to download your favorite antivirus program – Safebytes.

Create a bootable USB antivirus drive

Another solution is to save and run an antivirus software program completely from a USB drive. Adopt these measures to run the anti-malware on the infected computer. 1) On a virus-free computer, install Safebytes Anti-Malware. 2) Connect the USB drive to a USB port on the clean computer. 3) Double-click the Setup icon of the antivirus software to run the Installation Wizard. 4) Select the drive letter of the flash drive as the place when the wizard asks you exactly where you want to install the antivirus.

If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such an issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has virtualization support, the best thing you can do now is to fix this black screen issue. There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.

Option 1 – Try to disable Hyper-V

Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third-party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:

• In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
• Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
• Click the OK button and then restart your computer.
• Now try to use VirtualBox again and see if the problem is fixed.

Option 2 – Try to disable 3D Acceleration

The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:

• Open VirtualBox on your computer and select the virtual machine.
• Next, click on the Settings button and go to the Display section.
• After that, look for a checkbox named “Enable 3D Acceleration” located on your right-hand side and then uncheck it.
• Save the changes you’ve made and reboot your PC and see if you can now run the virtual machine without any problem.
