Driver Verifier is a built-in tool in Windows 10 that monitors device drivers on your computer, if it detects issues with drivers, it will attempt to fix the issue. If you are encountering Blue Screen for a Driver and after running Driver Verifier you get another with message DRIVER_VERIFIER_DETECTED_VIOLATION ten follow this article step by step in order to solve it.

There is a chance that you will maybe even have to do this in safe mode, if that is your case, login into safe mode and proceed, otherwise proceed normally.

1. Update Device Drivers

   the most common issue with the blue screen is old Drivers, in most cases, graphical drivers, update all Drivers with the latest versions and see if this will resolve the issue.

2. Stop or uninstall Virtualization software

   Virtua machine software is a great way to have a safe environment and to experiment while preserving your Windows installation intact, however sometimes due to the nature of these applications they can be a case for blue screen errors. Stop virtualization software to see if it will remove the issue. If that is the case, try another virtualization application

3. Disable Driver Verifier

   Press ⊞ WINDOWS + X to open the secret menu
   Click on Command Prompt (admin)
   Inside command prompt type: verifier and press ENTER
   Select the Delete existing settings radio button
   Click Finish
   Reboot your computer

4. Reset Driver Verifier

   Press ⊞ WINDOWS + X to open the secret menu
   Click on Command Prompt (admin)
   Inside command prompt type: verifier /reset and press ENTER
   Reboot your computer

5. Use system restore

   Rollback Windows to the previous state where everything was working fine.

In the past, CDs, DVDs, and floppy drivers used to be the primary sources of external storage for many users – that is until the USB storage devices took over. These days, a lot of devices no longer have a built-in CD or DVD writer or reader as it contributes to the thickness of the device. On the other hand, there are still various devices that still come with a built-in CD or DVD writer or reader. However, recently, users who still use CD or DVD on their devices reported a problem where the CD or DVD icon is not visible in the File Explorer as well as in “This PC” or the My Computer page. The cause of this issue is still unknown at the time of writing, but there are still some potential fixes you can try to fix it. You can try to update or roll back the device drivers or apply some tweaks in the Registry Editor. For more details, refer to the given options below.

Option 1 – Try to update or rollback device drivers

The first thing you can try to fix the missing CD or DVD icon is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties. Note that the concerned drivers will be listed under the DVD/CD-ROM drives section as well as the IDE/ATAPI Controllers section.
• From there, look for the following drivers:
  • ATA Channel 0.
  • ATA Channel 1.
  • Standard Dual Channel PCI IDE Controller.
• Now, right-click on each one of the listed drivers and update them all. You could also try to roll them back to their previous versions.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver.

Option 2 – Try to use the Registry Editor

• 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 key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318}
• After that, look for the DWORD values named “UpperFilters” and “LowerFilters”.
• Right-click on each one of these DWORD values and select Delete.
• Now restart your computer and see if it fixes the problem.

Option 3 – Try creating a new Registry entry

There is another option you can try in the Windows Registry to fix the missing icon of the CD/DVD. You can try adding a new entry. How? Refer to these steps:

• Tap the Win ­+ R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesatapi
• From there, right-click on “ATAPI” and select New > Key.
• After that, name it is “Controller0” and right-click on the sub-key and then select New > DWORD (32-bit) Value.
• Now name it as “EnumDevice1” and double click on it and then set its value data to “1”.
• Click OK and restart your computer to apply the changes made successfully.

Anxiety from all these digital threats lurking everywhere? An antivirus program can help put your mind at ease.

What can a virus do to your device?

A virus is malicious software that can affect pretty much any device and does so in a variety of ways. Be it your computer, your phone or your smart lightbulb — as long as there’s access to the internet, malware can get to it.

How exactly does this kind of attack manifest itself? Well, there’s a wide variety of effects ranging from mild to severe. Among other things, they depend on which type of malware attacks your device — a virus, spyware, ransomware, adware or something else.

These are some of the things you can expect to happen:

• Slow performance
• System crashes
• Theft of data and sensitive information
• Connectivity issues
• Constant browser redirects
• Strange messages sent to your contacts 
• Interference with files

It really can be the stuff of nightmares. So, if you want to sleep peacefully knowing that your devices are completely safe, you should definitely consider getting an antivirus.

P.S. don’t let its name fool you — an antivirus does indeed protect your devices against more than just viruses.

What is antivirus software exactly?

Antivirus software is designed to help you battle and ward off malware. Basically, it scans your device to detect any suspicious activity and offers tools to get rid of the culprit. 

At first, antiviruses were developed to fight against viruses only, but nowadays they cover a lot more ground. Here are some of the biggest benefits of getting yourself a powerful defender.

Advantages of antivirus software

1. It fights those pesky ads

Look, constant ads that pop up everywhere aren’t the absolute worst thing that can happen on your computer. If anything, they are annoying, like when you’re trying to sleep but that one fly in your room just won’t stop buzzing.

Now, there’s a free, well-established solution for that — installing an ad blocker. And we’re about a hundred and ten percent sure you’ve already done that on each and every browser you use.

However, “if I can’t see it, it doesn’t exist” isn’t the most ideal approach for your online safety. Ad blockers can’t block everything and they won’t protect you from potential adware. An antivirus on the other hand offers that layer of protection against malware snuck into pop-ups and spammy websites.

2. It protects you from hackers

Hackers don’t target government institutions only. They’ll target regular people too if they have something to gain.

There are different types of hacking, such as phishing e-mails, transmission of malicious programs, credential reuse, denial of service and more. In any case, they take control of your device and hijack your data.

The good thing is that, as threats evolve, antiviruses evolve too and there are tons of quality programs on the market that can keep you secure for an affordable price.

3. It keeps your files and data safe

When malware enters your device, it can target pretty much any file and get access to any and all data.

Installing an antivirus program will make sure that every single file, new or old, is monitored at all times, warning you against threats immediately. That way, you can make sure to react before your other files become infected and data is lost or stolen.

Another great thing for data protection is that the best antivirus software normally comes with a password manager, so no one can use malware to steal your passwords.

4. It blocks all kinds of malware

As we already stated, malicious attacks can be performed in many ways and malware comes in in different shapes an sizes, such as:

• Trojan horse
• Spyware
• Ransomware
• Adware
• Rootkit
• RAT (remote access Trojan)
• Keyloggers
• Worms
• Botnets

Nowadays, antivirus software is designed to fight against all of these types. That’s why more often than not we hear the term ‘antivirus’ used interchangeably with ‘anti-malware,’ like in this article.

5. It keeps your children protected

You can’t keep your eyes on your kid every second of the day and you can’t protect them from everything. But at least you can limit their exposure to the threats they can encounter at every corner of the digital world.

An antivirus program will block harmful or suspicious websites and ads, which is great both for you and your children. To take it a step further, though, many such programs come with special parental controls and offer monitoring as well. It’s a great solution for keeping your kids safe online without sounding like the irritating, overbearing, controlling parent who “just doesn’t get it!”

How to pick one

There are definitely lots of different antivirus programs out there, both free and paid. We recommend you look for a paid option, since free ones are unfortunately a lot more susceptible to being compromised through malicious attacks.

Now, there are a few factors to consider when choosing the right software. If you use your PC for basic things then a basic antivirus will suffice. However, the more complex your use and the more sensitive the data you deal with, the stronger it needs to be.

It’s also crucial that you take into account the features it includes. As we already mentioned, some programs have additional security options. For example, depending on the package you select, Bitdefender provides:

• Webcam and mic monitoring
• Parental control
• Firewall
• VPN
• Password management
• Identity theft protection

Some are included in plans and some are separate products, so make sure to check out all the offers.

And don’t worry if you have multiple PCs or you’re looking for protection for your smartphone or tablet as well; Bitdefender has suitable solutions for your needs. Of course, you can also just pick their classic antivirus software if you’re not in need of advanced protection.

Another important point is how regularly the software is updated and enhanced. The more frequent the updates the better, as bugs can make the program more vulnerable. Other things we advise you consider are user-friendliness, impact on performance, reputation (user reviews especially) and, of course, price.

The bottom line

Fact is: anyone can be a malware victim. Don’t let it be you.

You can’t put a price on peace and security, so don’t be reluctant to pay for yours — especially since a lot of options out there are extremely affordable. Is $159.00 a year really too much to pay for cross-platform protection for up to 10 devices? We don’t think so.

Explore your options and protect your files and data before it’s too late.

Error Code 0x8024001b- What is it?

At its most basic level, Error Code 0x8024001b is an error that can cause problems with the installation and updates of software and operating system updates. The most common version of this error appears in Windows 10, but a similar error with a matching code number has been present in previous versions of the operating system, back through Windows 7.

Common symptoms include:

• Programs freezing or locking up during use
• The appearance of an error message regarding installation difficulties
• Computer shutting down or freezing during operation
• Difficulty in running multiple programs at the same time

Solution

Error Causes

There are two main causes for Error Code 0x8024001b, both of which are fairly simple:  Updates needed for the Windows Update tool itself and software that causes Windows Update to fail during installations through conflicts in system files. While these may seem like technical issues, these problems are actually easily resolved with a few simple steps. The average user can use the methods listed below to fix the problems on their own.

Further Information and Manual Repair

For users who want to address Error Code 0x8024001b for themselves, the steps below can be followed to address the two primary causes for the error. If you have difficulty in completing these steps or are not confident in your computing skills and ability to follow the listed steps, contact a Windows repair technician.

Here are the top methods to resolve Error Code 0x8024001b on your own:

Method One:  Check for Updates to Windows Update

In some cases, the Windows Update tool may need an update for itself. When you attempt to run updates or install wizards for other software, it can cause conflicts with the Windows Update process, slowing down your computer or causing it to freeze.

If you are attempting to run multiple installations or updates at the same time, it may also cause Error Code 0x8024001b to arise on your computer.

To resolve this issue, close out all programs, with the exception of the Windows Update tool. Within the tool, select “Check for Updates” and install any updates that are needed. When finished, you should restart your computer to ensure that all updates have been fully applied before attempting any other installations or updates.

Method Two:  Uninstall Conflicting Software

Another problem that can cause Error Code 0x8024001b is the presence of conflicting software. If Error Code 0x8024001b has only recently appeared on your computer, consider removing any software that has been added to your computer, running the Windows Update process, and restarting your computer before attempting to reinstall the problem software.

With any method that you use, it is important to remember to keep your Windows Updates current at all times. This is the best way to avoid the appearance of Error Code 0x8024001b and similar errors in the future, as stacked up updates are more likely to cause issues and conflicts with your other installed software and operating system.

While there are some tools out there that claim to be able to fix Error Code 0x8024001b for you, it is important to always thoroughly investigate the publisher and distributor of such software, as some of the tools available on the Internet will actually introduce malware and adware on your computer in the name of “protecting” your computer or resolving an error.

If you have tried to use both methods above and have not fully resolved Error Code 0x8024001b, get in touch with someone who is a qualified computer repair professional and is familiar with your particular version of the Windows operating system to assist you in finalizing your resolution.

Method Three: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Waol.exe Error — What is it?

From the various report, it is now clear that no one is prone to Ransomware attacks. Cyber-criminals never target any specific field of the user workgroup for this Ransomware attack. But in past few years, it has hugely affected home users, businesses, organizations.

We can say, Ransomware victims come in all shapes & sizes. Many business owners think that they will never be attacked by Ransomware crooks because their business is not so big. But that’s not true.

A huge proportion of Ransomware attacks happened in small sector businesses because of their weak security resistances.

Some leading negative consequences of Ransomware attacks faced by almost every victim are:

1. Permanent or temporary loss of proprietary or sensitive information.
2. Lots of trouble in performing regular operations.
3. Huge financial losses sustain for restoring up your files and systems.
4. Latent harm to the reputation of an organization.
5. Even making the Ransom payment doesn’t guarantee the safe releasing of your encrypted files.
6. Attackers get the victim’s money along with their banking details.
7. Getting the decrypting files doesn’t mean malware infection has completely been removed.

Ransomware put a tremendous impact on disturbing business operations and in the end, leads to data loss situations.

Here are some huge impacts of Ransomware attacks on business are:

1. Damage or loss of all the crucial information
2. In the Ransomware post-attack period Business disrupts a lot.
3. Destruction of hostage data, file, and system.
4. Business downtime
5. Victimized company’s reputation dropdown
6. Productivity loss

Apart from the ransom, the cost of downtime because of restricted system access will bring major concerns.

It’s a fact that due to downtime victims may has to pay a cost of ten thousand dollars daily.

As, Ransomware is becoming more and more widespread, so all companies require to brush up on their annual cyber-security goals. Moreover, approach for some appropriate implementations of Ransomware recovery plans and commit sufficient funds in their IT budgets for cyber-security resources.

Among the most effective impact of Ransomware, “data encryption” is very hard to deal with.

Meanwhile, this victim is completely restricted to access any of their encrypted data.

The only way for unlocking these encrypted files is through the decryption key which only belongs to hackers.

Many times, the decryption key is given to the organization, after the payment of the ransom. But there are also some cases when data is not handover to the victim, even after the ransom payment.

The main risk that generates with “operational impact of Ransomware” is on the businesses. Can you just imagine, what will happen if all of a sudden entire services or processes of your business halt down?

Well, this dreadful Ransomware threat is so impactful that it can:

1. Close down the entire plant
2. Freeze manufacturing control system
3. Make other backlogs

All the damages that occur due to downtime can be a major one and can have so many consequences.

A well-organized strategy of backup and recovery will not certainly make the Ransomware attack painless.

As this takes an extensive amount of money and time for data restoration.

Apart from that, the decision of recovering your system using the backup moreover depends on three things:

1. First the amount of data loss that is considered acceptable by your business or organization.
2. Up to how extent, the impact of Ransomware has spread
3. How fast the Ransomware attack was spotted.

However, in many cases, data gets so encrypted that you can’t revert back to the restore point. At that time external backup is considered the best option.

Among the wide-reaching impact of Ransomware “Data loss” is the most effective one.  As it starts from little disruption and leads to permanent business failure.

Sometimes data loss in a Ransomware attack leads to disclosure of all your confidential information which ends up in fines and lawsuits.

Attackers always look for backup files and folders after encrypting your system data. So that user can’t retrieve their corrupted file from the backup. Such dreadful activities make this Ransomware threat so profitable and effective.

Victims don’t have any choice left either they have to pay the ransom or they have to face their risk of data loss.

Signing in to a computer that runs a Windows 10 version OS is usually fast and straightforward. However, there are instances when signing in takes too long especially if there are a lot of programs in the Startup. So if many things are loading as soon as you log into your computer, it will slow down the sign-in process. Aside from programs in Startup, it is also possible that there are too many users that are logged in to the account. In such a case, you will most likely encounter an error that says, “Your computer is running low on resources, so no new users can sign in. Please use an account that has already been signed in”. If you’ve encountered such an error when you try to log into your computer, read on as this post will be guiding you on how you can fix it.

Each time a user signs in to Windows 10, it will allocate resources in order to work smoothly. But, in many cases, the system is running low on resources which is why this error pops up and blocks a sign-in of a new user. To fix it, you can try to log out the existing users, or perform a Cold Boot, as well as run both the DISM tool and System File Checker scan.

Option 1 — Try to logout existing users

The first thing you can do is to log out the existing users. If you have a shared Windows 10 computer, you have to check if someone hasn’t logged out. It could be that some background task or there is an existing program that is still running under that account. So you have to make sure to ask the same user to log out in case there is some unsaved work. On the other hand, if that user is not around, then you reboot the computer right away.

Option 2 — Try Performing a Cold Boot

You could also try to perform a Cold Boot to fix the problem. A Cold Boot is a process that makes sure that the Windows 10 Kernel shuts down properly and releases all the resources held by any account. To perform a Cold Boot, just press and hold the physical power button on your CPU until it goes off. After that, boot your computer regularly and see if you can now log into your account without any error.

Option 3 — Try to run a System File Checker scan

System File Checker is a built-in command utility in Windows 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 cause why you’re getting the error when you log into your computer. To run the SFC command, follow the steps given below.

• Boot your computer into the Advanced Recovery mode and from there open Command Prompt.
• 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.

 Now restart your computer and see if the problem is fixed or not.

Option 4 — run the dism tool

You might also want to run the DISM tool. This tool is known to repair potentially corrupted files in your system as having them could also system issues like the “Your computer is running low on resources, so no new users can sign in” error. To repair these corrupted system files, you can run the DISM commands:

• Go to the Advanced Recovery mode and select Command Prompt.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the problem is now fixed.

The third time is charm saying goes but not when we are talking about Microsoft. Print spooler is again in focus, in a bad way.

This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw came to light shortly after and was subsequently patched (with mixed success).

Microsoft is once again advising its customers to disable Windows print spooler after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

«An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.»

Stop this service right away or you are risking a potential attack.

1. Press ⊞ WINDOWS + X to open the hidden menu
2. Click on Power Shell (admin)
3. In Power Shell type in the following command to check if spool service is running: Get-Service -Name Spooler followed by ENTER
4. If spooler service is running type in the next command to stop it: Stop-Service -Name Spooler –Force and press ENTER
5. Then follow with this command to disable it at startup: Set-Service -Name Spooler -StartupType Disabled followed with ENTER

That’s it, we hope a patch will come soon for all the people that are using network printing and indeed need this service running in order to do work.

If you encounter an error message saying, “ERR SSL VERSION OR CIPHER MISMATCH” while visiting a website, then it is not primarily your fault as an end-user. In fact, it can happen on any website like Chrome, Edge, Firefox, and even Internet Explorer. Getting this error means that the website you are visiting is using an SSL certificate which your browser seems to be rejected because there is some issue with the certificate. It is also possible that the certificate that’s downloaded on your computer is corrupted or that your computer configuration for TSL/SSL is misconfigured.

Here are the complete details of the error message:

“A secure connection cannot be established because this site uses an unsupported protocol, Error code ERR_SSL_VERSION_OR_CIPHER_MISMATCH”

To resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error, refer to the options given below and see which one works for you.

Option 1 – Try to access the website with the only HTTP

The first thing you can do is to try accessing the website using HTTP instead of HTTPS. If you can open the website using HTTP then it means that the problem is in the website itself. And if you are the website owner, you can check the following:

• Check if your website’s SSL certificate name is mismatched. Here you need to ensure that the name and alias of the websites match with the actual website URL where the certificate is installed.
• Second, check if your server is using the RC4 Cipher. If it is, then you need to fix that.

On the other hand, you may also check if your CDN also supports SSL since most of the CDN nowadays supports SSL. All you have to do is configure it correctly and it should be good to go.

Option 2 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR SSL VERSION OR CIPHER MISMATCH error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on.

If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
• Restart the browser.

On the other hand, if you were using Firefox when you go the error, here’s what you have to do.

• Open Firefox and in the address bar, type “about:config” and hit Enter.
• If a warning appears, just click on the “I accept the risk!” button to proceed.
• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

Building your skill set could be a very important thing, especially in today’s world, and what’s the best way other than online learning classes. You are not exposing yourself to pandemics, staying safe in the warmth of your home and most of the courses are free.

Academic Earth has been built with one simple premise: Everyone deserves access to education.

Lead by this kind of mindset on Academic Earth you will find well, academic courses similar to ones found on edX and Coursera, but from mentioned sites here all courses are free and you will find only academic ones, there are no entrepreneur or expert courses here, just pure academic ones.

If you wish to see and learn something the way it is taught in Harvard, Berkeley, MIT, etc this is the place for you.

Khan Academy

https://www.khanacademy.org/

Khan academy is completely free and it is offering courses matching certain grades for children. It is offering courses for all 8 years of elementary school, math courses for high school and college with some coursework on topics like science, arts & humanities, reading, life skills, etc.

Despite not being on the same level as some university courses presented on other mentioned websites Khan Academy is a good place to learn a lot of basic skills that you could build upon later.
