Protestware, what it is, and why it is a bad thing

Error 451 - What is it?

This is a typical SMTP error code. SMTP is the abbreviation for Simple Mail Transfer Protocol. It is an internet standard for email transmission. In other words, SMTP is a text-based protocol in which the sender communicates with the mail receiver by issuing commands and receiving a response code. The SMTP error 451 is displayed in the following format:

‘451 Requested action aborted: local error in processing’

This error message indicates that the program cannot send more messages and the server has hit the limit. This is because some mail servers have limits. The sever stops the task of sending and receiving emails when this limit is achieved.

Solution

Error Causes

The causes of error 451 include:

• Server limit reached
• Email rejection due to a remote anti-spam filter
• Request denied by the server
• Viral infection

If you heavily rely on email communication with your business partners and colleagues, then it is advisable to immediately resolve this issue without any delays. Though this error is not fatal, you should repair it right away to avoid inconvenience. SMTP error code 451 can hamper your ability to communicate via email.

Further Information and Manual Repair

Here are some of the best, easy, and effective DIY methods that you can try to repair error code 451 on your PC.

Method 1

To fix this error, simply follow these steps:

• login to Linux SSH
• Open the file /etc/localdomains
• Nano/etc/localdomains and then add the domain name that is triggering email sending error

This will hopefully resolve the issue. Nonetheless, if the error code still persists, then try other methods given below.

Method 2 - Configure List Settings to change the server limit.

This can be done by accessing the List Settings then Outgoing Mail Server (SMTP) and then the Limit Feature. By accessing the limit feature, you can easily adjust the program to any limit of your choice. Configure the limit and save changes. Reboot PC to activate the changes made.

Method 3 - Scan and Remove Viruses.

This error code can also be triggered due to viral infection. If this is the cause, then simply download an anti-virus on your PC. Scan the entire system and remove all detected malicious programs like Trojans, malware, adware, viruses, and spyware. This will repair the error 451 on your system.

Method 4

If the error still persists, then contact your SMTP provider to check the situation and resolve it. There is a possibility the error is generated from the SMTP provider’s end.

If you suddenly encounter an error message that says, “This webpage is not available, Err_Connection_Closed” while browsing the internet or visiting a website and the website fails to load, then it means that there is some problem with your network connection. Similarly, you may also get other error messages like “Err_Network_Changed”, “Err_Connection_Reset” and “Err_Internet_Disconnected” errors in different browsers like Chrome, Firefox, and Edge. The problem lies in your Windows 10 computer and your internet connection since this is a network issue. So before you troubleshoot the problem using the suggestions given below, you need to refresh your browser first or you could also tap Ctrl + F5 on your keyboard to hard reload the webpage. If you’re still getting the same error message, then proceed to the guide below.

Option 1 – Try removing the Proxy

Removing the Proxy might also help you in fixing the “This webpage is not available, Err_Connection_Closed” 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 2 – Try using Google Public DNS

If the first option didn’t resolve the issue, you can try to use the Public DNS by Google and see if it can help fix the problem. 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 “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 3 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the Err_Connection_Closed error. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 4 – Disable both the Antivirus program and Firewall temporarily

There are times when antivirus programs and the firewall blocks a website that they consider to be malicious or even because of false-positive effects which is why you have to disable these programs temporarily as it might be the reason why you’re getting the “This webpage is not available, Err_Connection_Closed” error when trying to browse the internet.

Option 5 – Try to check the network cables and then restart your router

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 this error.

Option 6 –Try a Network Reset

When all else fails, you might have to consider resetting your entire network settings. Simply follow the steps below to do so.

• Click on the Start button and then click on the gear-like icon for Settings to open it.
• Next, select Network and Internet.
• Then scroll down and look for “Network Reset” – click on it and then click on the Reset now button.

Hello everyone, last time we were talking about disk cleanup and its benefits, but as you need to keep your System clean you should also clean and keep your hardware clean as well. Many system issues could be traced and could happen due to dirty PC. In this article, we will give you tips on how to perform safely cleaning on your computer and hopefully point good sides to it so you can develop a healthy habit of regularly cleaning it and keeping it tidy. Keeping your PC clean is not rocket science and you can do it with things you already and probably have in your house. One thing that I would recommend tho to purchase is antistatic gloves since they could prevent any kind of electrostatic discharges thus protecting your electric components. If you have the option to disconnect your PC and get it outdoors, I would highly recommend this approach since all the dust will be dusted outside and not in the room where your computer is. If you can not it is still ok, but since some portion of dust will be set in the room, you might need to dust your room after cleaning your computer.

Cleaning outside case & redusting inside

The first thing after disconnecting your computer is to dust it from outside, here you will need a vacuum cleaner and a brush, gently brush outside dust from your casing and vacuum it with your vacuum cleaner. You can use dustcloth for larger parts but use the brush for fans and connectors. After you have done cleaning the outside part, open the side of your computer casing, put on your antistatic gloves, and get a fine and soft brush, repeat dusting and vacuuming of the inner parts of your computer. If your computer is not regularly been cleaned this part will take a little longer since there would be excess dust inside and it will take a longer time to vacuum it all but keep going until you are left with no dirt.

Cleaning it inside

Fans are troublesome to clean since they will rotate when brushed and that could make you miss certain sports, in order to battle this get a tape and stick the fan into one position, brush areas that you can reach, then unstick it, rotate the head, stick it again in another position and dust off remaining areas which you could not reach before. If your computer is very dirty and some hard dirt is at bottom of the connectors, disconnect desired component and clean the connection properly. plug it back in immediately after cleaning to avoid connecting it somewhere else. Harder stains that could not be dusted could be cleaned with little alcohol. Get your dustcloth just a little wet with alcohol, just a corner, and gently wipe out sticky dust or spills if they are present. Leave it 10 minutes for alcohol to evaporate before plugging it back into an electric socket.

Thermal paste and cable management

If you have money and expertise, every 2 years would be a good idea to change the thermal paste on your processor, all you need to do is buy it from your local computer store online, remove the CPU fan clean the CPU and bottom of the fan and apply new thermal paste, place fan back and lock it. If you do not have expertise in this area, call someone who has to show you how it is done. When cleaning it would be a good idea if you do not have any cable management to do it now, nice and tidy cables not only look good, they also improve your air circulation inside your casing making your computer cooling better. once you are done with it, close back the casing side and plug it back in the wall.

Peripherals

When you are cleaning your computer, do yourself a favor and clean your keyboard, mouse, and screen as well. the keyboard can be quickly cleaned with compressed air in the can and screen and mouse with dustcloth. That's it, remember, keep your PC clean and tidy and enjoy the benefits of non-hardware malfunctions caused by dirt and dust.

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.

Windows 11 has arrived and it is being adopted all around the globe as we are writing this article. People are adapting it daily and today we will take a look at some advanced security features of the new Windows and do you really need an antivirus in it. It is not a secret that Windows 11 is the most secure Windows ever created, well at least up until now. It is packed with advanced security features like S-mode, Secure Boot, and Trusted Platform Module (TMP 2.0). All these new security features that Microsoft has advertised made people question are enough for security or do you still need third-party Antivirus software. In order to get an answer to this question, let us first take a detailed look at what each one of them does, and then we will give you our opinion on a given subject.

Windows S mode

For everyday home use, Windows 11 S mode is the most secure feature to have on your PC. This is a safety protocol where only apps from Microsoft Store are allowed to be installed. This eliminates the risk of installing third-party apps that may contain viruses or malware. Furthermore, S-mode protects your web browsing activity through the Microsoft Edge browser. S-mode does not allow you to use other browsers for security reasons. If you are using Windows 11 in S-mode, your PC and data will be secure in most parts. You need not buy antivirus when using Windows 11 in S-mode.

Windows Defender

The inbuilt security suite, Windows Defender was launched for the first time in 2006. Earlier to that it had existed and was known as Microsoft AntiSpyWare. Windows Defender has undergone significant improvements over the years. In its latest version available with Windows 11, Windows Defender offers a comprehensive range of security features. It is available under the Windows Security system. Some key security features include real-time virus and threat protection, account protection, firewall & network protection, app and browser control, parental controls, and device (hardware) security. This is comparable to security features offered by third-party antivirus programs.

Microsoft Account

In Windows 11, it is necessary to use a Microsoft account that will be linked to your device. This ensures the security of your data in case your device is lost or stolen. You just need to make sure that you have set a strong password for your device. Windows 11 also has Bitlocker that keeps your data in encrypted form.

Ransomware protection

In view of rising cases of ransomware, Microsoft has introduced dedicated ransomware protection in Windows 11. It works by stopping apps from carrying out unauthorized changes to files and folders. Users can choose their important files and folders that they want to be protected from ransomware.

Conclusion

As we went through Windows 11 security features, we can clearly see that it is packed heavily with many security features that aim to protect your data and your identity. Looking at them, one can clearly come to the conclusion that you do not really need any third-party software and that Windows itself can catch and protect most of the issues, and they would be right. If you use Windows 11 carefully, meaning that you go only to trusted websites, do not open suspicious emails, and click on suspicious links, if you do not use extensively external USB devices or mass media you really do not need any kind of third party protection, Windows built-in tools will do well and keep you protected. However, if you do come in contact with other people's USB devices if you surf over the net, and overall if you really want to be at peace of mind that you are protected you will still need a well-established third-party software protection solution. Windows 11 has great security features, best so far in any Windows but it is still far from being a solution that does not require dedicated protection solution. So do yourself a favor and grab one.

One of the worst problems users can encounter on their computers is Blue Screen of Death errors as some of them are quite hard to fix. One of them is the “The driver detected a controller error” Blue Screen error. It could be followed by “DeviceIdeIdeport0 OR”, “on deviceharddisk0dr0”, or “DR3” or the name of the drive or port that’s causing the problem. If you are one of the users who encountered this error, then the suggestions provided in this post would definitely help you in fixing the problem.

Option 1 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:

• Log onto your PC as an administrator.

• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 3 – Try to update the BIOS

Updating the BIOS can help you fix the ATTEMPTED_WRITE_TO_READONLY_MEMORY BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.

Option 5 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the “The driver detected a controller error” Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• Tap the Win + R keys to open Run and type mdsched.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 your preferred option, your computer 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.

Option 6 – Replace your motherboard

If your computer is still under warranty, you should consider replacing your computer’s motherboard in case the options given above failed to work in fixing the Blue Screen error.

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.

Windows 11 has been officially presented during Microsoft’s virtual event on June 24^th. Since presentation internet has been pretty live and busy with a discussion about it, some discussions are positive, some not so much but that is expected and it happens always when a new product is presented. One of information that we have about Windows 11 is tied to the home edition of this OS, Windows 11 home edition will require an internet connection at setup, and a Microsoft account in order to be installed and used. Previous versions of Windows could be installed and used with local accounts but it seems Microsoft has abandoned that idea for its new OS. OS will be delivered mostly as updates or via internet download so internet and online requirement make sense but why it cannot use the local account and must have a Microsoft one is beyond me.

In case you don’t know, a teletype network, also known as Telnet, is a protocol that is meant for internet or LAN communication which is used primarily to control other computers effortlessly. And it is available as a command-line utility in Windows and helps users in opening a command-line interface for the remote computer. However, a lot of users have reported an error that states, “Telnet is not recognized as an internal or external command, operable program, or batch file” when you try to use it. If you are one of these users, then you’ve come to the right place as this post will guide you on how to fix this error in Windows 10. This kind of error means that the Telnet utility is not installed on your computer but Telnet is a default feature in Windows 10 so the protocol mainly is not enabled yet. The Telnet client is disabled by default in Windows 10 and to fix this error, you can try to enable the Telnet Client via Programs and Features or try to install Telnet using an elevated Command Prompt.

Option 1 – Try to enable the Telnet Client via Programs and Features

The first thing you can do is to enable the Telnet client using Programs and Features since it is disabled by default. To do that, follow the steps below.

• Tap the Win + R keys to open the Run dialog box and type “appwiz.cpl” in the field and hit Enter to open the Programs and Features window.
• Next, select the “Turn Windows features on or off” from the options given on the left-hand side.
• After that, look for the Telnet client from the list and check the checkbox next to it and then click on OK to save the changes made.
• Now restart your computer.

Option 2 – Try to install Telnet via an elevated Command Prompt

If enabling the Telnet client using Programs and Features didn’t work, then you can try to do it using Command Prompt instead. To get started, follow the steps given below.

• In the Windows Search bar, type “command prompt” in the field and right-click on Command Prompt from the search results, and select the “Run as administrator” option.
• Next, execute this command to enable the Telnet client: dism /online /Enable-Feature /FeatureName:TelnetClient
• Once the command has been executed, close the Command Prompt and restart your computer.
