Bluetooth flaw, Android and Windows in danger
bluetoothResearchers have discovered 16 vulnerabilities in Bluetooth connections that could be exploited and make from minor to some serious damage to your device. The flaw can be used on chips manufactured by Intel, Qualcomm, and Texas Instruments while connecting to external devices like speakers, headphones, keyboards, mice, etc.

Who is affected?

Mentioned chips are used by many in a vast range of devices including big players with their products like Microsoft Surface laptops, Dell desktops, Samsung Phones, Google Pixel, and OnePlus handsets. The Bluetooth bug affects a wide range of devices, including smartphones, laptops as well as smart home gadgets. In total, more than one billion devices that rely on Bluetooth are believed to be impacted.

What is the damage?

The amount of damage possible with this flaw depends on the type of device with the chipset. Some devices can only be crashed after a specially crafted packet is sent to the flawed chip. If that's the case with your gadget, it can be easily resolved with a simple restart. With other devices, hackers can take advantage of the Bluetooth Classic flaw to remotely run malicious code. That could allow malware to be installed remotely. Researchers say vendors were informed about these issues months ago before the findings were published. The good news is this should have given plenty of time for the relevant patches to be pushed out that remedy the flaws. However, you'll need to make sure that you're running the latest version of the operating system to be protected by the patch crafted by the manufacturers.

Android Bluetooth threat

The researchers emphasize the lack of basic tests in Bluetooth certification to validate the security of Bluetooth Low Energy (BLE) devices. The BrakTooth family of vulnerabilities revisits and reasserts this issue in the case of the older, but yet heavily used Bluetooth classic (BR/EDR) protocol implementations. We would also advise users to disable Bluetooth on devices that do not need it. This way you can prevent attackers from sending you malformed LMP packets. Since BrakTooth is based on the Bluetooth Classic protocol, an adversary would have to be in the radio range of the target to execute the attacks. So, in a safe environment Bluetooth can be enabled.

A required device isn’t connected
If you are currently facing the “A required device isn’t connected or cannot be accessed” error with codes 0xc0000185, 0xc0000225, 0xc0000001, 0xc00000f, and 0xc000000e on your Windows 10 computer, worry not for this post will help you resolve this problem. All these error codes point out the same thing – your computer needs to be repaired. Some of these error codes are related to the “winload.efi” file which means that you are using the UEFI system. This file also loads up important drivers in order to start the Windows Kernel. And if you got a remark from any of these error codes indicating that there is a hardware failure or that the driver configuration is incorrect, then you must physically check if the wires are connected properly. This kind of error occurs mostly when your computer wasn’t able to locate the system files that are needed to boot up your computer. Thus, the only way to fix this problem is to correct the boot record. It is recommended that you utilize the “/RebuildBCD” option in order to rebuild the BCD files. To do so, follow these steps:
  • You can start by booting into the installation environment for Windows 10 from an installation media.
  • After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
  • From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
    • bootrec /FixMbr
    • bootrec /FixBoot
    • bootrec /ScanOS
    • bootrec /RebuildBcd
  • Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed error code 0xc000014c.
On the other hand, if rebuilding the BCD using the /RebuildBCD option didn’t help, you can try a crude way to rebuild the boot record from scratch. You can do that by following the given steps below which will export and delete/backup the BCD available in the system.
  • Go to the Advanced Recovery Mode.
  • From there, go to Command Prompt and execute the commands given below and make sure to enter them one after the other.
    • bcdedit /export C:BCD_Backup
    • c:
    • cd boot
    • attrib bcd -s -h –r
    • ren c:bootbcd bcd.old
    • bootrec /RebuildBcd
If it still didn’t help, then troubleshoot the problem further with the help of the following instructions.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the error. To disable Secure Boot, here’s what you have to do:
  • First, boot your computer into Windows 10.
  • Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
  • After that, go to the BIOS of your computer.
  • Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
  • Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
  • Select the UEFI Firmware Settings which will take you to the BIOS.
  • From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
  • Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
  • Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Run System File Checker

You could also run a System File Checker or SFC scan. All you have to do is select Command Prompt from the Advanced Options. Once you’ve opened Command Prompt, type the “sfc /scannow” command and tap Enter to execute it.

Option 3 – Disable the Early Launch Anti-Malware Protection

  • You need to restart your computer in the Start Menu first while holding down the Shift key on your keyboard.
  • After that, it will restart your computer to Startup Settings.
  • Now ensure that the 8th option is labeled as “Disable early launch anti-malware protection.
  • Then tap the F8 key since the aforementioned option above is listed at number 8. This should launch and load Windows on your PC with the Early Anti-malware protection disabled for that session only when you try to carry out the same task and then check if the error related to the Winload.efi file is now fixed.

Option 4 – Try to run Automatic Startup Repair

In this option, you need to boot your computer into the Advanced Startup Options and from there, run the Automatic Startup Repair and then wait until the process is completed.

Option 5 – Try to reset the BIOS or the UEFI Settings

If updating the BIOS didn’t help in fixing the error, you can try to reset the BIOS instead.
  • Start your computer and tap the F10 key during the booting process to enter the BIOS. If it does not work, you can try tapping the F1 or F2 key as well as the Del key.
  • Once you’re already in the BIOS, tap the F9 key to get the prompt to RestoreLoad default configuration now for the BIOS.
  • Next, click on Yes and then follow the next on-screen instructions that appear to set the BIOS back to its default settings.
  • Once you’re done restoring the default settings of the BIOS, restart your computer and then check if it now boots properly.

Option 6 – Try to physically check the hardware

You should also check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card of the computer. You might want 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.

Command prompt tips and tricks
Hello and welcome to errortools articles. Today we will talk about some great and awesome tips and tricks for the command prompt. Commands which can make your life easier and your workday more pleasant. That being said let's dive in right into muddy waters and swim out with new knowledge.

Tip 1: Read Motherboard information

There are a lot of reasons why you would like to read information from your motherboard, maybe you would like to upgrade your BIOS, perhaps you would like to know the serial number, maybe even the version number. Well, you can, type the following code into the command prompt and you will receive all information about your motherboard.
wmic baseboard get product,version,serialnumber,product

Tip 2: Copy command output to clipboard

Getting information from the command prompt to a word processor, into an email or any other medium can be somewhat troublesome, usually, people tend to screenshot or write from a command prompt into another destination, which could induce errors, and let's be honest, it is not practical. You can copy command output directly into the clipboard ready for pasting it anywhere with | clip. So for example if you would like to paste the directory structure of your c drive command would look like: dir c: | clip, now output would be placed into the clipboard ready to be pasted anywhere needed.

Tip 3: Erase data permanently

When you delete data on your hard drive, what really happens is that files are marked with a marker which marks that space for new data writing, but the data itself is still present and can be brought back. This sometimes could impose problems but if you would type: cipher /w:c Windows will write random data over each marked file deleting it forever without means to be brought back.

Tip 4: Manage your IP address

If you would like to play with your IP address and do fancy stuff with it do the following: ipconfig /release to release your IP address ipconfig /renew to renew your IP address ipconfig /flushdns to flush down DNS information and enjoy a new browsing start.

Tip 5: Check to see are packets reaching the desired location

You installed a new LAN printer, or a new switch, maybe you want to check if your new site is up and running. Use ping destination in order to see if TCP packets are reaching desired information, you can use it with a specific address like ping 192.168.1.1 or you can type a web address, for example, ping google.com and see if a connection can be established.

Tip 6: Get information about a specific command

So you learned some command prompt commands, but you do not know all of their configuration or switches? No worries, just type command/? to get a list of available switches for it. For example ipconfig/? will write you a list of available switches for ipconfig command.

Tip 7: Link and execute multiple commands one after another.

Let us say that for example, you would like to copy files into a different folder, then rename some and delete others and you need to do a couple of times. Instead of writing command after command once each one is finished link them with && and they will execute one after another.

Tip 8: Scan and repair files.

In order to scan files and repair broke or corrupted ones write in the command prompt: sfc /scannow. Please know that this command can take a long time since it is solely dependant on the number of files, their size, and the power of the computer.

Tip 9: Manage and configure your computer energy

Command powercfg will let you manage and see the power configuration of your computer. Just write powercfg/? and see what you need and want to change or get information about.

Tip 10: Associate files with applications

Windows already has some file associations defined, and some applications take over some type of files but if you want to take control into your own hand use assoc command. For example assoc.txt= "APPLICATION NAME" will associate txt files with the provided application.

Tip 11: Hide files and folder.

Do you have some folder or file with information that you do not want to be seen when someone opens file explorer? Use attrib +h <name of file> and hide file or attrib +h /D <folder name> to hide folder.

Tip 12: Get a list of installed computer drivers

Want to know which drivers are installed in your system? Use driverquery and take a look.

Tip 13: Find and locate shared folders

have you shared a folder but forgot which one and where? Do not bang your head on the wall, we have a simple solution for you. just type in command prompt net share and see everything.

Tip 14: Run commands as an administrator

You do not have administrator privileges? Do you want to bypass common blockades?
runas /user:yourdomainadministrator command
That is all that we have for you today, I certainly hope you have found something useful here and that we have managed to teach you some valuable things.

How to Fix Windows 10 Error 0x80070070

Error Code 0x80070070 - What is it?

Error code 0x80070070 can be presented when there is not enough drive space on the computer to install updates. It is possible to uninstall apps that are not often used, or you may delete or archive files that are no longer needed, you may even add on some removable storage space to free up the internal memory of the computer. The computer needs a significant amount of internal memory in order to be able to update the operating system properly. When the computer fails to have the amount of memory that is needed to perform the update, the error code 0x80070070 will be presented. If this error message is not resolved, your computer might be opened to other error messages, including error code 0x80072EE2.

Common symptoms include:

  • Windows cannot install updates properly.
  • You might not be able to install any additional programs or apps onto the computer.
  • When you check the memory of the computer, it may be very near its full capacity.

Solution

Restoro box imageError Causes

The Windows 10 upgrade error is caused by varying factors including a lack of computer space or resources, malware or virus infestation, or a clogged registry on the computer.  The error code 0x80070070 will present itself when there is not enough free space on the computer to perform the necessary updates on the computer. Too many apps or programs downloaded onto the computer, too many photos, or too much music may also contribute to the lack of storage space on the computer, thus contributing to the error, and the computer not being able to install the updates to the operating system properly.

Further Information and Manual Repair

There is not a lot of information regarding this error code, but there are a few methods to repair it when it does present itself. There are practical and manual steps that can be taken when trying to get the PC up and running. The primary way to solve this problem is to free up disk space and there are several ways to do this. Please do note that if these methods seem confusing or too complicated, do contact a Windows repair technician so that they may properly correct the problem. You will need to know for sure that it is error code 0x80070070 that you are dealing with so that these options are the best bet for fixing it.

Method One: Disk Cleanup

It is important to know how much space there is on the computer to start with prior to trying to free up any space. Use the free program on the computer called the Disk Cleanup tool. This will save time and free up some hard drive space while optimizing the computer to work better.

From the Start menu, browse to the Explore option, and then select This PC. Right-click on the C drive, and then select Properties. Select Disk cleanup. From here, select the options that you would like to clear. Make sure that the recycle bin is emptied of any temporary files or any error logs. Once done, select Okay.

How to Fix Task Scheduler Error 0x80070057
One of the important functions in the Windows operating system is the Task Scheduler. It can automatically run various tasks at a certain time where you’ll have to add a task that needs to be executed and then choose the time it has to run at. So when that time comes, the Task Scheduler will run the task automatically. However, some users reported getting an Error 0x80070057 where the Task Scheduler fails to start. This kind of error may be due to a disabled service that prevents the service from running. It is also possible that the antivirus program interfered with the task – it could be that the Task Scheduler is somewhat in the block list since the antivirus adds it to the list automatically when it’s installed. On the other hand, it could be that you lack administrator-level privilege which is why the Task Scheduler was not able to carry out the task. To fix this issue, here are some suggestions you can try.

Option 1 – Try to restart the Task Scheduler service

As mentioned, it is possible that the Task Scheduler service could be disabled. You could have disabled it when trying to enhance your computer’s performance and whatnot. Thus, you need to verify if it’s running or not and then restart it.
  • First, you need to tap the Win + R keys on your keyboard to open the Run dialog box.
  • Next, type “services.msc” in the field and click OK or tap Enter to open the Windows Services Manager.
  • You will see a list of Services and from there, look for the Task Scheduler service and double click on it.
  • After that, go to the General tab and click on the Startup Type options and then select “Automatically” from the given list.
  • Click on the “RUN” option and select the “Restart the Service” option.
  • And click on the “After Second Failure” option and then select the “Restart-Service” option again.
  • Now click on the “After Subsequent Failures” tab and select the “Restart the Service” option.
  • Finally, click on the Apply and OK buttons and then run the Task Scheduler and see if the issue is now fixed.

Option 2 – Try to temporarily disable the anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed in your computer. Thus, disabling them or any security software installed on your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like the Task Scheduler Error 0x80070057 due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program for the meantime and check if it fixes the error or not.

Option 3 – Run the Task Scheduler with an administrator account

Like pointed out, the Task Scheduler Error 0x80070057 may be due to the lack of admin privileges. Thus, you have to log in to an administrator account and try running the Task Scheduler again. It is also recommended that the administrator account you’re going to use as a password when logging in.

Option 4 – Repair the Task Scheduler by deleting corrupted tasks

Note that a single corrupted file can cause big problems so this option is quite important. And for you to delete a corrupted task or any task from the Task Scheduler, you have to use the Registry Editor if you are not able to use the Task Scheduler interface. To do so, follow these steps:
  • Tap the Win + R keys to open the dialog box for Run.
  • Next, type in Regedit and click on OK or tap Enter to open the Registry Editor.
  • Then navigate to this path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTree
Note: In this path, you can see all the tasks that are currently set in the Task Scheduler. And since it would be hard to tell which one of them is corrupted, you have to delete the latest one in Task Scheduler last. But before you do so, make sure that you take note of the ID of the tasks. And for you to get the ID, you have to select the task you wish to delete and double click on the ID string located on your right-hand side, and then copy it in the Notepad.
  • Right-click on the task name and then delete it.
  • After that, delete the very same GUID which you have copied earlier from these folders:
  • ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheBoot
  • ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheLogon
  • ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheMaintenance
  • ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCachePlain
  • ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTasks
Note: You might not see the same GUID from these folders but if you see it, delete it right away.
  • Next, navigate to this location: C:/Windows/System32/Tasks
  • Delete the very same tasks you just deleted from the Registry Editor.
  • Restart your PC and check if the Task Scheduler is back to its normal state or not.

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?

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. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million. Other notable viruses The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years: Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove. Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India. Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably. Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather. Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries. Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.” Explorezip: This worm used fake emails to spread to every machine on thousands of local networks. Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million. Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs. Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates. Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

Intel i9 Alder Lake better than AMD Ryzen 9
Alder LakeIf we are to believe news from Intel, new series of processors based on Alder Lake architecture are about to be released somewhere in October. Alder Lake is the 12th Generation Core of Intel processors and it is meant to have all advantages of the current CPU structure. I9 is aimed to pack a punch against its competitors with technology including eight high-performance Golden Cove cores (P-cores) with Hyper-Threading and eight energy-efficient Goldmont (E-cores) equipped with a 30MB L3 cache and operating at high clock speeds. During the benchmark test, the new CPU outperformed all of Intel’s previous Rocket Lake structure processors which is logically expected but the big surprise came from results that indicate better performance than Apple’s new M1 processor even in single-threaded performance which is supposed to be best in that field. Another surprise was really beating AMD Ryzen 9 in each field. If we take into account that i9 has 16 cores in total and can process 24 threads against Ryzen 9 with 16 Cores and 32 threads this is an impressive feature. Now truth to be told Alder lake has massive L3 cache and microarchitectural advantages and consumes much more power but the results of performance are high. Also, note that this early CPU is not really a mass production one and maybe some things will still change but early results are very satisfactory. We will see what will price tag be since in this age of shortage and competition that will also play a big role in its overall success. Speaking of competition I eagerly await AMD’s response to this, in any way it seems that the CPU market is for some turbulence which is always a good thing for the final customer and I welcome it.
