Real-Time Scanning or Firewall is disabled on macOS

Steps 1–4below apply to all macOS versions. The final Additional stepssection contains specific steps depending on your version of macOS:
 
  • Step 1: Manually enable protection
    Try to enable the Firewall or Real-Time Scanning again:
     
    1. Open your McAfee product.
    2. If you see a blue Turn it on button like the one in the image below, click it:

      McAfee Total Protection screen showing the Turn on Firewall message
       
    3. If you don’t see a Turn it on button, click the settings gear Settings cog icon in the upper-right corner.
    4. Click Firewall (or ).    
    5. Click .
    6. Return to the main product window.
    7. Check to see if the Firewall or Real-Time Scanning are on. You can stop at this step if the issue is resolved.
       
  • Step 2: Make sure that the system extension isn’t being blocked
    Mac apps such as LiveSafe use important files called system extensions to interact with macOS. System extensions are also known as kernel extensions, or  When an app tries to enable a system extension during installation, macOS blocks it and prompts the customer to authorize the installation of the system extension:

    Alert message indicating "System Extension Blocked" on macOS

    When you see this prompt, open Security Preferences to enable the extension. If you didn’t see the prompt, or if you clicked OK to dismiss it, the McAfee doesn’t get authorized and you see the problems described above.
     
    1. Follow the steps in TS - McAfee installation error on macOS: System Extension Blocked to make sure that the McAfee is authorized.
    2. Return to the main product window.
    3. Check to see if the Firewall or Real-Time Scanning are on. You can stop at this step if the issue is resolved.
      Note: If still only Firewall remains disabled, see further steps at How to grant permissions in macOS Catalina and Big Sur to enable McAfee Firewall
 
  • Step 3: Remove any incompatible apps
    Make sure that you do not have any other third-party antivirus programs installed. If you have another antivirus app installed, it could cause a conflict, which stops your McAfee software from working correctly.
     
    1. See TS - How to remove incompatible third-party applications.
    2. If you removed a product, return to the main product window.
    3. Check to see if the Firewall or Real-Time Scanning are on. You can stop at this step if the issue is resolved.

       
  • Step 4: Reinstall your McAfee software
    If the steps above don’t fix the problem, reinstall your McAfee software. Use the steps in TS - How to install, configure, uninstall McAfee software on macOS. Don't forget to authorize the system extension when prompted (see Step 2 above).

    After reinstalling:
     
    1. Return to the main product window.
    2. Check to see if the Firewall or Real-Time Scanning are on. You can stop at this step if the issue is resolved.

Additional steps
If you still have the issue after following the steps above, we recommend that you either upgrade or reinstall macOS. The action that you take depends on your version of macOS.

Fatal Error: What It Is and How to Fix It

A fatal error is a type of error that forces a computer program to close or the entire operating system to shut down suddenly. This type of error is commonly associated with the blue screen of death in Windows, but less severe fatal exception errors only cause a single program to close.

In some cases, fatal errors are spontaneous and temporary, and you can safely continue using the computer without any additional problems. If fatal errors persist, and especially if these errors reoccur when using the same program or performing the same task, there could be a problem with either the hardware or software on the computer.

How Fatal Errors Appear

Fatal error messages typically appear when a program suddenly shuts down because of some type of failure, or when a Windows computer suddenly displays the blue screen of death before shutting down, or when a macOS or Linux computer suffers a kernel panic.

When a fatal error occurs, a message like one of these appears:

  • FATAL ERROR: Unhandled xxx Exception at xxx
  • A fatal exception xx has occurred at xxxx:xxxxxxxx
  • Fatal error detected, unable to continue. Terminating due to uncaught exception.

When you experience a fatal error message, whether or not it looks exactly like these examples, write down what you see. The specific type of error, and the series of numbers and letters that are often included, can help track down the problem.

What Causes a Fatal Error?

When you run a program on an operating system like Windows, and the program encounters something unexpected, it generates a message called an exception. These exceptions allow programs to run smoothly and operate normally, even when something unexpected happens.

When a program is given or generates an unknown or unexpected exception, the result is a fatal error. This same type of problem can also be referred to as a fatal exception, or a fatal exception error.

Depending on the severity of the error, you may be given the option to continue running the program, or the program may terminate automatically.

How to Fix a Fatal Error

Fatal errors can be caused by a variety of unexpected interactions between different programs, between programs and drivers, between programs and the hardware, and physical faults or defects in the hardware.

Follow these fixes to get to the bottom of the fatal error.

  1. Search for the error code to find specific instructions. Some fatal errors are fairly basic, but most error messages provide a code that can help you find specific information about the problem. If the error looks like this:

    • A fatal exception 0E has occurred at xxxx:xxxxxxxx

    The 0E is a code that might point you in the right direction. Run a search for the specific fatal exception error code, and see if you can find specific instructions.

    The other code, which usually follows the format of two sets of numbers separated by a colon, may also help. This code is less likely to yield results, but it's worth a quick search before you move on.

  2. Update the software. The developers may have released a patch designed to fix the specific problem. Most programs and apps either download and install updates automatically, provide you with an option to manually download and install updates, or prompt you to visit the developer's website and download the update.

    If you can't figure out how to update the software, check out our list of free software updater programs. These programs keep all your programs up to date.

  3. Update the drivers. Unexpected interactions involving drivers can cause fatal errors, and other problems, so it's always a good idea to keep the drivers up to date.

    If the drivers are up to date, roll back the drivers to earlier versions. There's a chance the old drivers were fine, but an automatic update introduced the fatal error. Check to see if any drivers were updated immediately before the problems started, and roll those back first.

  4. Uninstall any recently installed programs. There may be an unforeseen conflict between the programs, or something could have been corrupted during the installation process. After uninstalling the recently installed programs, check to see if the fatal exception error still happens. If it doesn't, reinstall the programs. If the problem comes back, submit a bug report to the developer.

  5. Restore Windows to an earlier state. If you saved system restore points from before the fatal errors appeared, restore Windows to one of those points. This step rolls back any changes made during that time span, which will fix the fatal error problem if it isn't related to a hardware glitch.

  6. Disable unnecessary background programs. You don't see these programs on the taskbar, but you can open the task manager to shut them down manually. In most cases, background programs can be left alone. However, there are cases where one of these programs may conflict with a different program in an unexpected way, causing a fatal error.

    Don't shut down programs you're unfamiliar with. You can safely shut down any program you originally opened, but closing unfamiliar or system-level apps and background processes may destabilize the operating system, necessitating a reboot.

  7. Delete temporary files. Temporary files save when programs are running, but sometimes these files aren't deleted when the program closes. If corrupt temporary files are the cause of the fatal exception errors, then removing these files will fix the problem.

  8. Free up space on the hard drive. Check how much space is on the hard drive, and delete old files if the drive is full. Leave about 10% of the total storage space free for smooth operation.

  9. Run chkdsk. If the fatal errors are caused by a problem with the hard drive, then running chkdsk can identify the error and either fix it or at least let you know what's going on.

  10. Rule out heat problems. If your computer overheats, it generates several fatal errors in addition to a variety of other symptoms.

    Verify that the fans work and aren't clogged with dust or debris. If you're comfortable taking the computer apart, check the internal fans and the heat sink. Carefully use canned air or a vacuum to remove any dust or debris that prevent the fans or heat sink from functioning efficiently.

    If you use canned air, hold the can upright to avoid spraying liquid inside the computer. Don't touch the components inside the computer if you aren't wearing a properly set up ground strap. If you aren't comfortable poking around inside a computer or laptop, seek professional assistance.

  11. Test the random access memory for problems. Memory errors generate fatal errors, although you may see a memory exception or an out of memory exception error instead. Run a memory test application. If you discover that the RAM is faulty, replace the defective component or components.

  12. Check the rest of the hardware. If you experience recurring fatal errors, and everything has checked out so far, you might have a subtle problem with some of the hardware in the computer. In some cases, replacing components like the hard drive or motherboard can fix fatal errors.

    This level of diagnostics is complicated, so you may have to seek professional assistance.

FAQ

  • To fix a Windows update error, close all other programs, pause any current downloads or updates, and run the Windows Update Troubleshooter. If the error occurs during an app update, uninstall and reinstall the app. 

  • If you see a “no language file found” error message, it could be an issue with a startup program. Remove any recently installed programs, run SFC, and perform a System Restore if necessary.

  • A system error code is a number and message that displays when Windows encounters an error. A stop code is an error message that appears when Windows completely crashes.

  • Applies to:
    Microsoft Office Outlook , Microsoft Office PowerPoint , Microsoft Office Excel , Microsoft Office Publisher , Microsoft Office Access , Microsoft Office PowerPoint , Microsoft Office Publisher , Microsoft Office Access , Microsoft Office Outlook

Original KB number:  

Summary

This article describes an error message that you receive in Microsoft Office that states that an antivirus program is preventing you from opening a file. You may receive this error message for the following reasons:

  • There is a compatibility problem between your antivirus program and Office.
  • The file that you are trying to open is infected with a virus that your antivirus program was unable to remove.
  • The file that you are trying to open has been damaged.

To resolve the first two problems, you have to update your antivirus program. To resolve the third problem, you have to try to recover the file. This article will show you how to do this.

Symptoms

When you try to open a Microsoft Office file, you may receive the following error message:

Your Anti-Virus software has blocked the file you were trying to open.

You should ensure your Anti-Virus software is fully up to date and try opening the file again. It is important to note that the blocked file may also contain a virus which your Anti-Virus software has not been able to remove. In this case you should treat the file with caution.

Note

An antivirus program helps protect your computer from viruses. To avoid viruses, you should never download or open files from sources that you do not trust, visit Web sites that you do not trust, or open e-mail attachments when your antivirus program is disabled.

For more information about computer viruses, see How to prevent and remove viruses and other malware.

Cause

This problem occurs when your antivirus software and its signature files are out of date, when the file that you are trying to open is infected with a virus, or when the file has been damaged.

Resolution

The resolution to this problem depends on whether your antivirus software and its signature file are out of date, whether your file is infected with a virus, or whether your file has been damaged.

To check whether your antivirus software and its signature file are out of date

To keep up with new viruses that are created, antivirus program vendors periodically provide an updated virus signature file that you can download from the Internet.

If you are experiencing this problem on a computer on which you have recently installed a new version of antivirus software from a CD, we recommend that you connect to the Internet as soon as possible to download the latest updates that are available from your antivirus software vendor.

List of antivirus software vendors

You may have to purchase a new antivirus program.

To check whether your file is infected with a virus

If you are experiencing this problem on a computer that has the latest version of your antivirus software, that has up-to-date signature files, and on which you can open all files except this one, it is likely that the file is infected with a virus.

If your file is infected with a virus, you should delete the file from your system. As soon as the file is deleted, you can re-create the file or restore if from a back-up if you have one.

If the file is damaged

If the file is damaged, the file cannot be handled correctly by either the antivirus software or by the affected Office program. Therefore, to be able to use the file again, you have to try to recover the file. For instructions about how to do this, please see the articles that are listed for the Office program that you were using when this problem occurred.

5 Ways to Fix the "An Unexpected Network Error Occurred" Issue on Windows

Network errors are nothing new for veteran Windows users and can be caused by a number of reasons. One specific issue that pops up when the users attempt to transfer large files from another device or server is the 'An Unexpected Network Error Occurred' error message. This is typically caused by an over-protective antivirus program, corrupt Windows Search service, and inconsistencies within the system.

While the error message states that there is an issue with the network, simply checking your Wi-Fi connection will not do the trick. Let's see how to resolve this problem with the utilities already present in your Windows operating system.

1. Disable You Antivirus and Windows Defender

If you cannot transfer large files from your network driver to PC to laptop, then the first thing that you should do is temporarily disable the security programs you are using on your system. This is because while the security programs protect your system from threats, there are times when they falsely classify the legitimate processes as harmful, interrupting their functioning.

In this method, we will be disabling third-party antivirus and Windows Defender Firewall.

1. How to Disable a Third-Party Antivirus Program

If you are using a third-party antivirus program, you can typically disable it by right-clicking on its icon in the taskbar and choosing Disable option from the context menu.

If this does not work for you, then try launching the program and look for the Disable antivirus temporarily option. The exact steps will be different for each program, but the basic principle behind the disabling feature remains the same.

2. How to Disable the Windows Defender Firewall

The Windows Defender Firewall also has a history of blocking secure processes as a result of false alarms. To disable it, follow the steps listed below:

  1. Type Windows Defender Firewall in Windows search and click Open. Alternatively, you can also navigate to Firewall manually by heading over to Control Panel > System and Security > Windows Defender Firewall.
  2. Choose Turn Windows Firewall on or off from the left pane.
  3. Checkmark the Turn off Windows Firewall options under both Public and Private network settings.
  4. Click OK to apply the changes and restart your PC.

2. Verify the Hard Disk's Format

Generally, Windows operating systems use two types of file systems: File Allocation Table (FAT) and New Technology File System (NTFS). These file systems play a crucial role in managing the system drives and the information stored in them.

If you are facing the error code 0xB on your system, we recommend you check the formatting of the destination drive where you plan on transferring the files. If the drive supports the FAT32 format, then you cannot transfer single files which are more than 4 GB in size. Any attempt of doing so is likely to result in a crash.

Here is how you can check the destination drive’s format:

  1. Launch File Explorer and head over to This PC.
  2. Right-click on the targeted drive and choose Properties from the context menu.
  3. In the following dialog, navigate to the General tab and check the format against File System.

3. Disable the Windows Search Service

This method might sound irrelevant, but there were instances where the users were able to fix the problem by simply disabling the Windows Search service. As per our research, this service’s process sometimes overlaps with the transferring process, resulting in a crash.

The solution, in this case, is simple, as all that you need to do is temporarily disable the Windows Search service. Once you are able to transfer files over the network successfully, you can switch it back on.

Follow these steps to proceed:

  1. Open the Run window by pressing Win + R.
  2. Type sprers.eu in the text field and click OK.
  3. In the Services window, right-click on Windows Search and choose Properties.
  4. Expand the dropdown menu for Startup type and choose Disabled.
  5. Click Apply > OK to save the changes.

You can now transfer the required files again and see if disabling the Windows Search service made a difference.

4. Modify Windows Registry

Another fix that worked for users was renaming a specific key in the Registry Editor. This fix has proven to be effective for both Windows 8 and Windows 10 users, and thus we recommend you give it a shot if you are comfortable using Windows Registry.

If you are going to proceed with this method, it is important that you create a Registry backup. Doing so will help you revert to the current working state of the Registry in case anything goes wrong. While you are at it, you can also enable automatic Registry backups to save time when a scenario like this pops up again in the future.

Once you have created a backup, follow these steps:

  1. Press Win + R together to open Run.
  2. Type regedit in the text field and hit Enter.
  3. Inside the Registry Editor, navigate to the location mentioned below:
  4. Right-click on Microsoft-Windows-DXP/Analytic and choose Rename from the context menu.
  5. Rename this key as Microsoft-Windows-DXP/Analytics.
  6. Exit the Registry Editor and restart your computer.

Upon reboot, check if you can now transfer the files without any problem.

5. Perform a System Restore

Windows creates restore points of your system occasionally (typically before performing critical operations), which are basically snapshots of the working states of your system. These restore points come in handy when you are facing an issue within the system and want to revert to a previous point in time when the system was working perfectly fine.

You can try to restore your system to a previous working state if you have come this far without finding a solution. However, it is important to keep in mind that restoring the system to a previous point will make you lose all the changes that you made after the restore point was created. This can include changing system settings, installing new applications, etc.

Unexpected Network Error, Now Resolved

Network errors can be frustrating, as the error codes do not give much information about what might be causing the issue. Hopefully, the methods mentioned above will help you get rid of the error for good. To stay away from such issues in the future, we highly recommend keeping your network drivers up-to-date at all times.

  • Please check if you have an anti-virus and/or ad-blocking program running in the background. Those types of programs have been known to prevent the Online Installer from doing its job. Try either adding the Online Installer as a trusted program or try disabling the anti-virus program temporarily while running the Online Installer.

  • If you get a file mismatch error it usually indicates problems with the internet connection. The most common cause is an unstable Internet connection, in which case retrying the download should solve the issue.

  • Make sure that you have the Controlled Folder Access option in Windows Defender disabled.

  • If you have your Documents folder in Windows on a network drive there might be permission issues happening and we recommend having it on your local system drive.

  • If you are on macOS then keep in mind that you will need to copy the Online Installer into the applications folder and launch it from there.

  • If you are running macOS then when you first start the Online Installer it prompts you to enter the username and password for your macOS user. This is to enable the Online Installer to download and install files on your computer. When you have filled in your macOS user password, the OI user interface will show and you will be prompted to log-in with your sprers.eu user account credentials.

    How to troubleshoot security error codes on secure websites

    For websites that are securely encrypted (the URL begins with "https://"), Firefox must verify that the certificate presented by the website is valid. If the certificate cannot be validated, Firefox will stop the connection to the website and show a "Warning: Potential Security Risk Ahead" error page instead. Clicking the Advanced button, you can view the specific error Firefox encountered.

    This article explains why you might see the error codes SEC_ERROR_UNKNOWN_ISSUER, MOZILLA_PKIX_ERROR_MITM_DETECTED or ERROR_SELF_SIGNED_CERT on an error page and how to troubleshoot it.

    For other error codes on the "Warning: Potential Security Risk Ahead" error page, see the What do the security warning codes mean? article. For Secure Connection Failed or Did Not Connect: Potential Security Issue error pages, see the article Secure connection failed and Firefox did not connect.

    During a secure connection, a website must provide a certificate issued by a trusted certificate authority to ensure that the user is connected to the intended target and the connection is encrypted. If you click the Advanced button on a "Warning: Potential Security Risk Ahead" error page and you see the error code SEC_ERROR_UNKNOWN_ISSUER or MOZILLA_PKIX_ERROR_MITM_DETECTED, it means that the provided certificate was issued by a certificate authority that is not known by Firefox and, therefore, cannot be trusted by default.

    Fx66WarningSEC_ERROR_UNKNOWN_ISSUER

    If you get this problem on multiple unrelated HTTPS-sites, it indicates that something on your system or network is intercepting your connection and injecting certificates in a way that is not trusted by Firefox. The most common causes are security error relative branch out of reach scanning encrypted connections, or malware listening in and replacing legitimate website certificates with their constant php syntax error. In particular, the error code MOZILLA_PKIX_ERROR_MITM_DETECTED indicates that Firefox detected connection interception, antivirus protection disabled. a serious error occured.

    Antivirus products

    Third-party antivirus software can interfere with Firefox's secure connections. You could try reinstalling it, which might trigger the software into placing its certificates into the Firefox trust store again.

    We recommend uninstalling your third-party software and using the security software offered for Windows by Microsoft:

    • Windows 8 and Windows 10 - Windows Defender (built-in)

    If you do not want to uninstall your third-party software, you could try reinstalling it, which might trigger the software into placing its certificates into the Firefox trust store again, antivirus protection disabled. a serious error occured.

    In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.

    Read this Microsoft FAQ page on how to turn off these family features for accounts. In case you want to manually install the missing certificates for affected accounts, you can refer to this Microsoft support article.

    Monitoring/filtering in corporate networks

    Some traffic monitoring/filtering products used in corporate environments might intercept encrypted connections by replacing a website's certificate with their own, at the same time possibly triggering errors on secure HTTPS-sites.

    If you suspect this might be the case, please contact your IT department to ensure the correct configuration of Firefox to enable it to work properly in such an environment, as the necessary certificate might have to be placed in the Firefox trust store first. More information for IT departments on how to go about this can be found in the Mozilla Wiki page CA:AddRootToFirefox.

    Malware

    Some forms of malware intercepting encrypted web traffic can cause this error message - refer to the article Troubleshoot Firefox issues caused by malware on how to deal with malware problems.

    In case you get this problem on one particular site only, this type of error generally indicates that the web server is not configured properly. However, if you see this error on a legitimate major website like Google or Facebook or sites where financial transactions take place, you should continue with the steps outlined above, antivirus protection disabled. a serious error occured.

    Certificate issued by an authority belonging to Symantec

    After a number of irregularities with certificates issued by Symantec root authorities came to light, browser vendors, including Mozilla, are gradually removing trust from these certificates in their products. Firefox will no longer trust server certificates issued by Symantec, including those issued under the GeoTrust, RapidSSL, Thawte and Verisign brands. For more information, see this Mozilla blog post.

    MOZILLA_PKIX_ERROR_ADDITIONAL_POLICY_CONSTRAINT_FAILED will be the primary error, but with some servers, you may see the error code SEC_ERROR_UNKNOWN_ISSUER instead. If you come across such a site you should contact the owner of the website to inform them of the problem.

    Mozilla strongly encourages operators of affected sites to take immediate action to replace these certificates. DigiCert is providing certificate replacements for free.

    Missing intermediate certificate

    On a site with a missing intermediate certificate you will see the following error description after you click on Advanced on the error page:

    The certificate is not trusted because the issuer certificate is unknown.
    The server might not be sending the appropriate intermediate certificates.
    An additional root certificate may need to be imported.

    The website's site topgearrussia.ru error might not have been issued by a trusted certificate authority itself and no complete certificate chain to a trusted authority was provided either (a so-called "intermediate certificate" is missing).
    You can test if a site is properly configured by entering a website's address into a third-party tool like SSL Labs' test page. If it is returning the result "Chain issues: Incomplete", a proper intermediate certificate is missing. You should contact the owner of the website you're having troubles accessing to inform them of that problem.

    Self-signed certificate

    On a site with a self-signed certificate you will see the error code ERROR_SELF_SIGNED_CERT and the following error description, after you click on Advanced on the error page:

    The certificate is not tipe error components. classes [cid] is undefined because it is self-signed.

    A self-signed certificate that wasn't issued by a recognized certificate authority is not trusted by default. Self-signed certificates can make your data safe from eavesdroppers, but say nothing about who the recipient of the antivirus protection disabled. a serious error occured is. This is common for intranet websites that aren't available publicly and you may bypass the warning for such sites.

    Bypassing the warning

    Warning: You should never add a certificate exception for a legitimate major website or sites where financial transactions take place – in this case an invalid certificate can be an indication that your connection is compromised by a third party.

    If the website allows it, you can bypass the warning in order to visit the site, even thought its certificate is not being trusted by default:

    1. On the warning page, click Advanced.
    2. Click Accept the Risk and Continue.
