If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“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.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.

If you always use Google Chrome when browsing the internet, then you might have come across an error saying, “This webpage is not available, DNS PROBE FINISHED BAD CONFIG”. If you do, then this problem certainly has something to do with the DNS since any error code which has “DNS” in it points out a network issue in the computer. Getting the DNS_PROBE_FINISHED_BAD_CONFIG error indicates that your computer is not able to connect the website because the Domain Name Server or DNS wasn’t able to resolve the website name into IP address or it is not available at all. So in this guide, we’ll help you sort out this issue in Chrome on your Windows 10 PC.

Option 1 – Check the Network Cables and restart your router then reconnect

The most obvious thing you can do first is to try checking if the network cables connected to your computer or router are properly connected or not. If it turns out that some network cables are not connected properly, then it’s probably why you’re getting the DNS_PROBE_FINISHED_BAD_CONFIG error in Chrome. And if your computer is connected via Wi-Fi, you need to make sure to restart your router once. In addition, you can also forget the Wi-Fi your computer is currently connected to and then try reconnecting again to see if it would work.

Option 2 – Flush the DNS and reset TCP/IP

Flushing the DNS and reset TCP/IP could also help in fixing the DNS_PROBE_FINISHED_BAD_CONFIG error in Chrome. To do so, refer to these steps:

• Click the Start button and type in “command prompt” in the field.
• From the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After opening Command Prompt, you have to type each one of the commands listed below. Just make sure that after you type each command, you hit Enter
  • ipconfig /release
  • ipconfig /all
  • ipconfig /flushdns
  • ipconfig /renew
  • netsh int ip set dns
  • netsh winsock reset

After you key in the commands listed above, the DNS cache will be flushed and the Winsock, as well as the TCP/IP, will reset.

Option 3 – Try to remove the Proxy

You can also try to remove the Proxy as it might also help you in fixing the DNS_PROBE_FINISHED_BAD_CONFIG error. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 4 – Change the DNS

Try to use the Google Public DNS If the first option didn’t work, you can try to use the Public DNS by Google and see if it can help fix the DNS error. You have to modify the DNS settings in your system explicitly and use the DNS IP addresses.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Clear Chrome’s browsing data

If your browsing data in Chrome hasn’t been cleared for some time now then that might be the reason why you’re suddenly getting the DNS_PROBE_FINISHED_BAD_CONFIG error when you browse the web. To fix this error, you need to clear your web browsing data. Refer to the following steps to do so.

• Tap the Ctrl + Shift + Delete buttons to go to the Clear browsing data section in Chrome.
• Next, set the time range to “All time” and tick all the boxes and then click on the Clear data button.
• After that, restart the Chrome browser and try to open the website you were trying to open earlier.

Option 6 – Try running the Chrome Cleanup tool

In case you don’t know, there is actually a built-in malware scanner and cleanup tool in Chrome that helps you get rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and other things that could affect the performance of the browser.

Dune, arguably one of the best science fiction novels ever written was brought to a big screen first time by David Linch. Sadly movie itself went through development hell and a lot of troubles and the end result was somewhat strange. The audience was divided on it, some hated it, some loved it but for sure it left a mark in cinema history. Years have passed and just when people forgot about ever receiving another try on a book adaptation Denis Villeneuve has brought his vision of Frank Herbert's novel into its full glory on a big screen. The interesting thing about this new Dune movie was that from the start Denis envisioned it as a two-movie part openly saying that book itself is too complex to be done in a single movie. But, the issue arises when information about Dune part two was hanging on a thread on how well Dune part one will be received and performed in the box office. This naturally brought all kinds of speculation and worry among fans of the franchise, especially because the movie itself was really good and well made. Well for all of you fans and people who wanted to see a continuation of the story can rest at peace now since the Legendary picture has officially announced and green-lighted Dune part two. The budget was given and we can expect part two at the beginning of 2023.

As you know, the Windows 10 operating system, as well as other Windows versions, comes with the Windows Firewall. In Windows 10, the firewall allows users to install and run a third-party firewall. This kind of firewall works independently to block any suspicious activity on your computer. However, recently, some users reported that they are getting a notification on the Startup saying,

“Windows Firewall and <Third party firewall name> Firewall are both turned off; tap or click to see available options”.

This particular error could be caused by a lot of factors but when you manually check the firewall, you’ll find that there really is nothing wrong with both the Windows Firewall and the third party firewall. So if both the Windows Firewall and third-party firewalls like McAfee, Comodo, and many others are both turned off in Windows 10, then you need to do several things to resolve the problem – you need to check the supporting services that are required and uninstall and then reinstall the third party firewall on your computer. For more instructions, refer to the options provided below.

Option 1 – Try enabling all the supporting services for the firewall

The first thing you can do to resolve the error with the firewall is to check all of its supporting services by following these steps:

• Tap the Win + R keys to open the Run utility and type “services.msc” in the field and then hit Enter to open the Windows Services Manager.
• Next, look for the Windows Defender Firewall service among the given list of services.
• Once you found it, make sure that its Startup Type is set to Automatic and that the status of the service is Running. So if it’s not running, just click on the Start button.
• In addition, you also have to make sure that the following services’ status is set as follows:
  • Xbox Live Networking Service: Manual
  • Base Filtering Engine: Automatic
• Once done, start the firewall again and check if the error is now fixed or not.

Option 2 – Try to uninstall and reinstall the third-party firewall

It is possible that the firewall error might be due to an error with the compatibility of the installation in Windows 10 and the third-party firewall. Thus, the next thing you can do is to uninstall the third-party firewall and then reinstall it again. Once you have uninstalled the third-party firewall, you can download its latest version from its official website and install it again. This should fix the error with the firewall.

Computer viruses are malicious applications that have the ability to self replicate and spread over the system and various devices, just like viruses in organisms. We all know that computer viruses are bad and that you should avoid them however you can. So in this spirit, we are taking a deeper dive into what kind of viruses exist and how they function.

1. File-infecting Virus

A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.

2. Macro Virus

This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.

3. Browser Hijacker

This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.

4. Web Scripting Virus

A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.

5. Boot Sector Virus

These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.

6. Polymorphic Virus

This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.

7. Resident Virus

A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.

8. Multipartite Virus

A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.
