Fix Msvcr120.dll_clr0400.dll Missing Error

We have often talked about the security of your computer, we have been giving you tips and tried to explain how to best protect your computer from various attacks and malicious software. Today we will be talking about antivirus applications. Antivirus software has become the kind of a must-have in every computer in this day and age. When you think about it, our systems are connected to the internet most of the time if not always, and therefore kind placed in from the line of various cyber-attacks. Here antivirus software comes into focus, especially because it has evolved long from just a simple virus removal tool to full security suites. We will be going through the best of these applications in order to present both their good and bad sides and hope that we will help you in picking the right one for you. Remember, picking either one of the presented solutions is way better than not having one at all. The list is made from best down in our opinion so number one is highly recommended.

List of Best antivirus applications of 2021

1. BitDefender

   In our opinion the best overall security protection suite for this age and time. Bitdefender has cemented itself as number one a few years back and it holds that status even today. It has top-of-the-game virus protection, an incredible amount of features, safepay banking online protection and it is amazingly cheap. Its downside we could say is that it can be annoying sometimes, especially if you set it to maximum protection and paranoid mode. In this case, it will often ask what to do and how to behave leading to minor annoyances.

2. Norton antivirus

   Norton antivirus is well known to older computer users, this package has been around a long time and it is our pick for closest one to challenge top place because of its packed features. The number of features it has are really stunning and it comes also with great and maybe best-browsing protection of all candidates. It also has a backup tool bundled with it but the reason why it is in the second place is that it is taxing to the system and can have a real impact on computer performance. Great protection is important, but so it is working on it without slowdowns.

3. Kaspersky

   Another one of the old antivirus software on the list. Kaspersky Lab was once top tier antivirus software but it dropped down due to its high prices, later they have changed their pricing to be more in trend with other rival companies but many have switched to something else. Today it still packs one of the best antivirus engines with fast and configurable scans. It also has very impressive anti-ransomware features but sadly most of the things it just simply does for you leaving you to fully trust it since you cannot really configure much. It is not in step with new technologies and it is lacking some features like support for the Chrome browser that places it lower in our ranking.

4. Trend Micro antivirus

   The biggest sell point for this antivirus application is probably its ease of use and user-friendliness. It also packs a great antivirus engine and impressive anti-ransomware performance but sadly it comes with very limited configurability and somewhat lack of features comparing it with the top three entries. Never the less a very user-friendly application that you can configure without knowing any kind of tech talk, everything is laid out in simple English.

5. Avira

   Perhaps best known for its free version, Avira has a premium one that is well better worth than the free version. Strong suites of this software are mostly aimed at the internet with its great anti-phishing and web protection along with a low price for all of its features. Sadly in the domain of virus protection, there are some reports from independent websites that its antivirus engine is not so great, it will offer you moderate protection but not the best.

6. Webroot Secure Anywhere

   If you are on the lookout for software that has a great virus database and plenty of features but is also incredibly light weighted and fast then look no further, Webroot Secure Anywhere is an application for you, incredibly fast and incredibly small is a great solution for older machines. It keeps all of its databases up in the cloud and this feature among its great advantages is also its greatest disadvantage since if you are out of the internet you will not be able to have the latest virus definitions available to you making this tool very situational.

7. Avast

   Avast has many great protection features and it is very highly configurable. The firewall comes also in its premium edition and it offers great virus protection including a file shredder and awesome WI-FI inspector for an extra layer of security. This package would be higher on the list if it was not for its lack of WEB protection and its tool on the system resources.

8. Sophos home antivirus

   Lack of features and somewhat strange user interface are downsides of this software but on its positive side it has good antivirus engine and its user interface is very friendly. Where it shines though is in its price, for one affordable price you get protection for 10 devices making this option a great choice for anyone wanting to protect more devices or just use a single license for the whole family.

9. ESET antivirus

   Greatly configurable antivirus software with tons of options and very light on system resources makes ESET one of the best out there. Virus engine and database is also top tier but some testing labs have reported that protection offering is not really what it is advertised and if we talk about its strong suite of a great many options and configurations it is at the same moment its downside since it is not very friendly to novice and beginner users.

10. McAfee antivirus

    McAfee antivirus comes in its package with unlimited VPN service and if we take look at the top tier pricing plan it is a great investment. Sadly for its entry-level price, it covers only a single device and it was reported that it packs little outdated virus engine if we compare it with its rivals. Nevertheless, it still offers good virus protection and if you take into account the VPN that comes with it, it can find its users.

Conclusion

No matter which antivirus you choose you will not go wrong, after all any protection is way better than none.

   If the previous 2 methods failed and you still get the missing error, try downloading the file from Microsoft and placing it in C:\Windows\SysWOW64

4. Reinstall C++ redistributable

   Having an incorrect C++ redistributable package can be an issue of the problem, get the latest version from Microsoft and reinstall it.

Ever gotten an e-mail offer that seemed just a little bit too good to be true? Might’ve been a phishing attempt! These are everywhere and can come in many different forms. 

So what’s phishing exactly, how can you detect it and how can you keep safe?

What is phishing?

Phishing (pronounced like fishing) is a type of cyberattack that tricks the user into trusting the source and revealing sensitive information. Fishing being the perfect analogy, the bait is a legitimate-looking site, e-mail or file and when you take a bite, your identity, banking information and much more can be revealed and stolen.

Some phishing attempts are incredibly obvious, others are super elaborate. Like with most types of malware, cybercriminals have become extremely well-versed in phishing and anyone can fall for it. To help you recognize and avoid it, we’ll take you through a couple of phishing types and give you tips on what to do if faced with them.

Phishing techniques

E-mail phishing

This is actually the most common type of phishing. A cybercriminal creates an e-mail containing stuff like attractive offers, legitimate-looking attachments or links and makes it appear as though it’s coming from a trusted source.

For example, it looks like it’s coming from your bank or your favorite retailer. The logo looks legit and the structure of the e-mail seems familiar, so you might get tricked into clicking on whatever clickable content is in it.

Unfortunately this exposes your device to malware that hands your data off to the hacker, who can decide what to do with it further.

SMS and social media phishing

Like the above example, you could be approached with lucrative offers or links via text messages or social media messages. Typically, the messages seem relevant to the user as they will be made to look like they’re related to apps or services you’re using.

Voice phishing

Voice phishing attacks are schemes that appear as though they’re coming from a credible number. Normally, you’ll get a call about something related to credit cards or taxes to get you into a state of worry, leading you to disclose personal information on the phone.

Spear phishing, whaling and BEC

Spear phishing normally targets specific individuals within a company who are likely to have access to sensitive data. Spear phishers spend time collecting information they can use to reach out to the individual looking as trustworthy as possible. They’ll typically lead with something relevant, for example mentioning an upcoming company event, and make a seemingly legitimate request.

Whaling is a more elaborate form of spear phishing, which targets people in even stronger positions such as executives or high-value individuals. The ultimate goal is to get them to transfer financial or other sensitive information that can be used to compromise the entire business.

BEC, or Business e-mail compromise, is a specific spear phishing technique carried out via e-mail. While there are many ways this is done, most commonly you’ll see instances where the phisher poses as a CEO or similar executive, or as a lower-level employee in specific positions (e.g. sales managers or financial controllers).

In the first situation, the impersonator reaches out to employees requesting them to transfer certain files or pay invoices. In the second situation, the phisher takes control of the employee’s e-mail account and sends false instructions to other employees in order to obtain data and information from them.

What can you do?

There are many ways you can be aware and spot a phishing attempt. Here are some tips:

• Always check the sender’s address in your e-mails, even when they seem to come from a familiar source.
• In any instance where payment information is requested, be very, very careful.
• If you are receiving attachments you never asked for and definitely didn’t expect, better not click on them. 
• Beware of content that transmits a sense of urgency (sales deals, urgent updates to login credentials, etc.).
• Bad spelling and grammar are usually a telltale sign of phishing.
• Links that look shortened (e.g. Bit.ly) or just suspicious in general - if you have a bad feeling, do not click on them.
• If you are receiving threats, you probably shouldn’t be clicking on anything in that message.
• Always examine first-time senders in detail.
• Block suspicious e-mail addresses, numbers and social media accounts.
• If you are receiving a coupon for free stuff… You aren’t.
• If you’re being asked to update your payment details by a service you use, such as Netflix, chances are it’s an impersonator.

Those are some of the ways to identify and prevent phishing attacks. However, sometimes phishers disguise themselves a little too well or a misclick happens and there you go - you’ve been exposed to malware.

This won’t happen if you invest in powerful protection software from the get-go, though. A good antivirus program like Bitdefender will keep you safe from becoming a victim of phishing scams. In fact, it will protect you from malicious attacks overall.

Be it your household or your business you’re concerned about, there are a bunch of different packages and options available, providing different kinds of cybersecurity services. That’s the only way you can ever really be sure you aren’t at risk of a digital attack.

Summary

Have you ever been targeted by phishers and didn’t know that’s what it was until you read this article? Many can relate. Protect yourself before it’s too late!

Strange and anxious message no internet, secured can happen even during when everything is ok and you do indeed have internet. So in order to fix this issue please keep on reading.

If you suspect this might be the issue, uncheck the IPv6 box under your connection’s Properties.

When you receive Error 0x800704C8 when trying to move a file inside Windows 10 operation is stopped and it can not continue leaving you with the file in its original location without a copy. Several issues can be the cause of this type of behavior and error and after some digging and analyzing we are bringing you various solutions for this error and how to fix it.

Ownership issues

It turns out that not having ownership of fie can cause this error and prevent you from copying it. For some reason, Windows can assume that file is owned or used by another application or process and thus prevents you from making a copy since you do not have ownership of it. Resolving this particular issue will require you to install a third-party application that is tailored for this kind of task. After some talk and research, we found out that there is a freeware application that can solve this issue quite fastly. Unlocker is the name and the download link is here. Once downloaded, install it and run it. Once inside the application browse to the location where you need to change the ownership, click on it to select it, and click OK. Use the No Action drop drown menu to select Move, then click OK

Antivirus Issue

As with other file and application issues, this error could also be a product of antivirus marking it inaccessible to Windows and thus preventing copy or move operation on it. note: Do not turn off Windows defender since it was proven that it is not the cause of this kind of error, so if you are using only Windows defender you can skip this solution. How temporary turning off each security suite is different and it depends on the application itself we can not cover in detail the procedure here. Go to your security suite manufacturer's website and get information there or if you want, go directly to applications and features inside Windows and uninstall the software.

Visual Studio issue

• If the file you are trying to move is part of a Visual Studio project then the issue can be linked directly to Visual Studio itself, luckily the solution is quite easy. All you have to do it to exit Visual Studio and then run it with administrator privileges.
• In order to run Visual Studio with elevated privileges locate its executable file and right-click on it.
• Choose properties and go to the compatibility tab
• Inside compatibility tab check box that says run this program as an administrator

Corrupted system files

If the previous solutions have not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

   SFC scan is a built-in Windows tool for solving corrupted system file issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC

Windows users need to be on high alert. Microsoft has confirmed a critical vulnerability has been found in all versions of Windows which presents an immediate threat, and you need to act now. A critical new zero-day hack has been found which affects all Windows versions. Tracked as CVE-2021-34484, the “zero-day” flaw enables hackers to breach all versions of Windows (including Windows 10, Windows 11, and Windows Server 2022) and take control of your computer. Microsoft mistakenly thought it had patched the vulnerability (which was first found in August) when it was publicly disclosed in October. But the fix itself was found to be flawed, something the company admitted, and this drew even more attention to the vulnerability. Microsoft subsequently promised to “take appropriate action to keep customers protected” but two weeks later, a new fix has still not arrived. Luckily the third-party security specialist 0patch has beaten Microsoft to the punch with a ‘micropatch that it has now made available for all Windows users “Micropatches for this vulnerability will be free until Microsoft has issued an official fix," 0patch confirmed. You will need to register for a 0patch account and install its download agent before the fix can be applied, but with 0patch fast becoming a go-to destination for hot fixes which beat software companies to the punch this is a no brainer. Hopes will be high that Microsoft can release an effective patch sooner rather than later but, until then, all Windows users must act now if they want to be safe.

The Makecab.exe process that’s running on your Windows 10 computer is a program that compresses the Component-Based Servicing log or CBS log files and they can get really huge if they’re not compressed. As a result, it would utilize important space on your operating system although makecab.exe does not consume high CPU resources in doing so. However, there are times when it recreates thousands of instances of itself and could cause overconsumption of system resources which slows down your computer. So when the makecab.exe process causes high CPU usage in your system, this could mean that there is a failed Windows Update. In addition, the high CPU usage of the makecab.exe process could also mean that your computer is infected with a virus or malware. Whichever the case is, you can check out several possible solutions that are given in this post to resolve the problem.

Option 1 – Try to delete log file using File Explorer

The CBS log files could reach up to 20GB size and so if you delete them, it would help in saving space in your computer and since they’re not much of use, deleting them won’t negatively affect the system at all. To delete the CBS log files, all you have to do is open the File Explorer and then go to C:/Windows/Logs/CBS and from there, open the CBS log files and delete them all. Doing so should ease the load in the makecab.exe process since it no longer has to compress the CBS log files. As a result, the process would be more relaxed. After that, you can restart your computer and check if the problem’s now fixed.

Option 2 – Try deleting the log file via Command Prompt

You can also try to delete the log files using an elevated Command Prompt. Refer to these steps to do so:

• Type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option.
• Next, type the following command and hit Enter to execute it:

del /f %windir%logscbs*.log

• Restart your computer afterward once the command has been executed. This should end the high disk usage by makecab.exe, if not, proceed to the next given options below.

Option 3 – Uninstall any suspicious programs you’ve installed recently

If you have recently installed some programs on your Windows 10 computer, and since then you’ve experienced high CPU usage brought on by makecab.exe, then you might want to uninstall those programs.

• Tap the Win + R keys to open the Run dialog box
• Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
• From there, look for the suspicious programs you’ve installed, select them and then click on Uninstall to remove them.
• After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.

Option 4 – Try running Disk Cleanup

You might want to run the Disk Cleanup utility as it is a useful tool that could delete temporary and useless files on your computer.

• Tap the Win + R keys to open the Run dialog box and then type “cleanmgr” in the field and hit Enter to open the Disk Cleanup window.
• After that, select the drive you want to clean.
• Now click OK to clean the disk and restart your computer.

Option 5 – Try to run System File Checker scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files and missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• 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.

• Restart your PC.

Option 6 – Try scanning your computer using Windows Defender

As mentioned, the high CPU usage of makecab.exe might be caused by some malware or virus in the system and so to eliminate it, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

If you suddenly receive an error message that says, “The selected boot device failed, Press <Enter> to Continue” during an installation on your Windows 10 computer, you should know that this kind of error can occur when you use a USB stick as well as a DVD Disk to boot from. This error indicates that some settings inside your BIOS are not compatible with the bootable device that you have created. Note that fixing this kind of error does not vary from device to device at all. All you have to do is change some settings in the BIOS and create a proper bootable disk. Follow the options given below to fix the “The selected boot device failed, Press <Enter> to Continue” error. The options below do not have to be necessarily followed in the same sequence since you can create a bootable USB drive before you change some settings in the BIOS.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. 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 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

One of the worst Blue Screen of Death errors you can encounter is the UNMOUNTABLE_BOOT_VOLUME BSOD on Windows 10. In this BSOD error, your computer won’t be able to properly boot. Meaning to say, even if you want to reinstall Windows, you won’t be able to back up your important files. Thus, it wouldn’t be really feasible to fix the system files, and besides, reinstalling Windows 10 would take a lot of time, not to mention resources. The UNMOUNTABLE BOOT VOLUME error is the kind of BSOD error that occurs if Windows is not able to access the volume that contains the boot files. Resolving this BSOD error won’t be easy but you will surely manage by following the suggestions laid out below but before you go on, make sure to create a System Restore Point.

Option 1 – Try checking the hardware

If you got the UNMOUNTABLE BOOT VOLUME BSOD error while trying to update your computer to a higher version of Windows, then you need to check if you have the compatible drivers for the disk controller as well as re-check the drive cabling and make sure that it is properly configured. And if you’re reusing either ATA-100 or ATA-66 drivers, ensure that you have an 80-connector cable and not the standard 40-connector IDE cable.

Option 2 – Try using Automatic Repair

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

Option 3 – Try fixing the Master Boot Record or MBR

The MBR or Master Boot Record is the location and is where the architecture of the operating system is installed. Thus, if either the location or the architecture has tampered with, it can cause lots of BSOD errors like the UNMOUNTABLE BOOT VOLUME error.

• Boot your computer into Safe mode with Networking using the Advanced startup options which you can access by tapping the F2 or F8 key. Once you’ve accessed the Advanced startup options.
• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

bootrec /fixboot

• After entering the command, wait until the process is completed and then restart your computer to apply the changes made successfully.

Option 4 – Run the CHKDSK command to repair hard disk errors

Running the Chkdsk utility could help you fix the UNMOUNTABLE BOOT VOLUME error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• The command you entered will scan the hard disk for any errors and will automatically fix it if it finds some issues. Wait for the process to be completed and then reboot your PC.

Interrupts are designed so that the resource requests don’t get into a headlock when it comes to the hardware level. To simply put it, it is used to break a loop that never ends. Aside from that, developers also designed levels in order to prioritize interrupts. It is also known as “Interrupt Request Level” or IRQL. And if you suddenly encounter a “Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL” error, this means that a driver has accessed a memory location illegally while NT is operating at a specific IRQL. The Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL is a fatal driver coding error and as an end-user, there isn’t much that you can do to resolve it but if you’re a developer, then this means that your code is trying to access an invalid memory location. You could check on different parameters such as memory location that was referenced and code addressed which referenced memory. The technical parameters are:

• a memory location that was referenced
• IRQL at time of reference
• 0 = read, 1 = write
• code addressed which referenced memory

As mentioned earlier, if you are an end-user, there is nothing much that you can do to resolve this problem, but worry not for there are still possible solutions that could help you in fixing it. Refer to the suggestions laid out below to fix Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL error.

Option 1 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time 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.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Run the Memory Diagnostic Tool to check for Memory leaks

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.
