Steam Deck, a modern PC handheld console
steam deckValve has announced the first gaming PC handheld console: Steam Deck. At its core, Stead Deck is just a portable, small PC in little casing. It uses AMD Zen 2 CPU and RDNA 2 GPU architecture, has 16GB of RAM, Wi-Fi, and Bluetooth. It is a portable device with both a touchpad and joystick packing a seven-inch screen with a resolution of 1280x800 (16:10 aspect ratio). The screen has an ambient light sensor for automatic light adjustments same as your modern mobile device. Stating to Valve battery will hold up from two to eight hours depending on the activity of the user and what exactly he is doing. The handheld comes also with a carrying case.

Steam Deck operating system and software

Out of the box, Steam Dock comes with the latest Valve’s version of SteamOS 3. Just for comparing, the steam box was coming SteamOS 2, so this new Linux-based OS is aimed to provide better performance and better compatibility. Naturally, all Linux games in your Steam library will work right out of the box but Valve has something called PROTON inside OS, it is emulation software based on Wine that will supposedly let you play all of your Library games on a given OS. One big thing to mention here is that this is PC after all meaning that if you do not like having SteamOS on it you can install Windows instead and so far as we know it will support Windows 11. Now with Windows 11, you will be able to play all of your Steam games and run any kind of Windows software on it including EPIC store, battle.net, and others.

Cost and release date

The initial release date is set for December 2021 and today on July 16th Valve is opening you can reserve your copy if you want to pre-purchase. Follow this link if you want to reserve your copy. Reserve your Steam Deck device The price of the device will depend on the memory capacity which you would like to have. Please note that each of the 3 offered devices will have the same hardware, the only difference will be in memory available, and the most expensive version will also have anti-glare screen, everything else is identical. 64GB model will be $399, 256GB model will have the price of $529 and largest one with whooping 512GB will be $649

Conclusion

Valve ventures into the digital hardware domain again but it is unsure will they make it this time. Both Steam machine and their controller were in long run failed and later unsupported products so perhaps some customer caution is advised. Although having a handheld PC is tempting I would advise seeing how the overall market will accept this contraption before throwing money into it.

10 Worst Computer Viruses in history
Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

viruses10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent. Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server. Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation. Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught. Wondering what makes the world’s most secure computers so safe? See the Tech@Work guide: Upgrade to the World's Most Secure and Manageable PC

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging. This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses. As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last. Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs. The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter. Need to up your remote work security game before there’s another entry on the list of most deadly computer viruses? See our guide: How to Work Remotely and Securely

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch. The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries. The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms. Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage. Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red. Can your printer get a virus? See our cool infographic: The State of Printer Security

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic. The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note. The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million. Where will cybersecurity go next? See our guide: The Future of Cybersecurity

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack. Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware.

Fix Orange Screen of Death Error in Windows
The Windows 10 Orange Screen of Death, unlike Blue Screen of Errors, is quite an uncommon error where the hardware is the culprit which is mostly caused by some issues with the GPU. If you are currently facing this problem, then you’ve come to the right place as this post will guide you on what you can do to fix it. There have been reports from users that the Orange Screen of Death is caused by various reasons. Some users reported that they encountered Orange Screen of Death when they were watching a YouTube video, while some were not able to boot into their Windows 10 PCs and encountered an error instead of that either says, FAULTY_HARDWARE_CORRUPTED_PAGE or WHEA_UNCORRECTABLE_ERROR error. In addition, this error can also occur when your computer wakes up from Sleep or while using BitLocker, or while you use a second monitor. Whatever the case is, you can try updating your drivers or lower the clock speed of the GPU. You could also try to fix the DRIVER_IRQL issue in case it’s the one that triggers the error or performs Automatic Repair or uninstalls any recently installed software.

Option 1 – Update your Graphics card drivers

One of the possible reasons why you’re getting the Orange Screen of Death error is most likely related to the Graphics card drivers in your computer. Thus, the first thing you can do to resolve it is to update these drivers by following these steps:
  • 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 2 – Try to uninstall software you’ve installed recently

If you have installed a software or two recently and then suddenly encounter this Orange Screen of Death, then they are most likely the culprits. The best thing you can do is to first check the System Log in the Event Viewer for any additional information in case it’s not the GPU but some other driver or device that’s causing the error. Once you have identified the culprits, uninstall them and see if the error is fixed.

Option 3 – Try disabling Overclocking

If overclocking is enabled, you might have to disable it as some users reported that the WHEA_UNCORRECTABLE_ERROR 0x00000124 error started to appear right after overclocking. To disable it, follow the steps below.
  • Go to the Start Menu and open Settings.
  • Next, select Update and Security and go to the Recover tab.
  • From there, click on Restart now in Advanced startup. This will restart your computer.
  • Once you’re in the Advanced startup, go to Troubleshoot and then select Advanced Options.
  • From there, select the UEFU Firmware Settings.
  • Now click on Restart. Once your computer has restarted, it will automatically open BIOS.
  • From the BIOS, go to the Advanced tab and navigate to Performance and then look for Overclocking.
  • Once you’ve found Overclocking, make sure that it is disabled. If it’s not, then disable it and then save the changes made by tapping the F10 key.
  • Start your computer normally and check if the WHEA_UNCORRECTABLE_ERROR 0x00000124 error is now fixed.

Option 4 – Use the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues. And so if you want to fix the Wdf01000.sys Blue Screen error, you need to use the Driver Verifier Manager:
  • Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
  • After that, select the option “Create custom settings”.
  • Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
  • Next, select the option “Select driver names from a list” option.
  • Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
  • Then click on the Finish button.
  • Open Command Prompt as administrator and execute this command – verifier /querysettings
  • The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
  • Open the Command Prompt as admin again and run this command – verifier /reset
  • The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 5 – Try to run the Automatic Repair Utility

You might also want to use Automatic Repair in fixing the 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 on 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.
