Fix Netwtw04.sys BSOD Error in Windows 10

Blue Screen of Death errors or Stop errors are indications that something’s wrong with your computer. So when you encounter one, you must find out what the root cause of the problem is before it gets out of hand. One of the BSOD errors you might encounter on your Windows 10 computer is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” error.

As you know, system files or .sys files are some of the essential parts of the Windows operating system. It is a repository of system driver settings used by the Windows operating system in order to communicate with the connected hardware and devices. They are essential for the normal functioning of the operating system. A lot of Windows 10 users are facing this particular Blue Screen of Death error whenever they open an app or disconnect external devices from the system.

The Netwtw04.sys file is a part of the Intel PROSet/Wireless Wi-Fi software. And so when you might encounter two kinds of Stop errors for the Netwtw04.sys driver file such as:

  1. “DRIVER_IRQL_NOT_LESS_OR_EQUAL What failed: Netwtw04.sys.” – This kind of error message signifies that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high.
  2. “SYSTEM_THREAD_EXCEPTION_NOT_HANDLED What failed: Netwtw04.sys” – This error message indicates that the root cause of the error might be incompatible drivers with the operating system. In general, the root cause of the Netwtw04.sys BSOD error might be due to several reasons such as corrupted files, incorrect device driver configuration, malicious programs, outdated drivers, bad drivers, corrupted Windows Registry as well as some damaged or corrupted system files.

Whichever of the two error messages you got, you can try the troubleshooting options given below to fix the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error.

Option 1 – Try to rollback your Network driver

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
  • Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
  • Then select each one of them and double-click to open a new mini window.
  • After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
  • Now restart your computer to successfully apply the changes made.

Option 2 – Try to update the Network drivers

If the present Network driver is giving you a headache that is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error, then you need to update the Network drivers. To do so, here’s what you have to do:

  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
  • Then right-click on each one of the Network drivers and update them all.
  • Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 3 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Netwtw04.sys failed BSOD error. SFC is a built-in command utility that helps in restoring corrupted files as well as 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.

Option 4 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

  • Open the Command Prompt as admin.
  • Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
  • The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the CHKDSK Utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD 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.

  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

  • Wait for the process to be completed and then restart your computer.

Fix HAL INITIALIZATION FAILED Error 0x0000005C
When your computer boots up or when it just woke up from sleep but it suddenly encounters a Blue Screen of Death error, saying, “HAL INITIALIZATION FAILED error with STOP CODE 0x0000005C”, then read on as this post will give you some fixes that might help in resolving the problem. You will see the following error message on your computer’s screen when this error pops up:
“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. If you’d like to know more, you can search online later for this error: HAL_INITIALIZATION_FAILED HAL INITIALIZATION FAILED 0x0000005C”
This kind of Blue Screen error indicates that there is a hardware or device driver problem in your PC. Aside from that, it also signifies that the initialization of the Hardware Abstraction Layer or HAL has failed. This happens only during the relatively short period that the Windows operating system is being initialized, specifically during phase 4 of Windows startup. What’s worse about this kind of Stop error is that it does not just go away after a computer reboot. You may have to 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, follow the fixes prepared below.

Option 1 – Run CHKDSK command to repair hard disk errors

Running the Chkdsk utility could help you resolve the HAL INITIALIZATION FAILED error with STOP CODE 0x0000005C. 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 restart your computer.

Option 2 – Run the DISM tool

If the first option didn’t work, then running the Deployment Imaging and Servicing Management tool can help you resolve the HAL INITIALIZATION FAILED error as it will repair the Windows System Image as well as the Windows Component Store in Windows 10.
  • After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
  • Next, type in this command: DISM /Online /Cleanup-Image /RestoreHealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 3 – Update the Device drivers

  • Tap the Win + R keys to launch Run.
  • Type in msc into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. Look for the device driver you and then select either “Update driver” or “Uninstall device”. And if you find any “Unknown device”, you need to update it as well.
  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
  • If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
  • Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 4 – Try removing any external hardware

You might also want to remove any connected devices and external hardware in your computer as it might help in fixing the BSOD error.

Option 5 – Disable Fast Start-up

If you want your computer to boot faster, then you might have enabled Fast Start-up. This feature is ideal for computers that are using a hard disk drive. However, turning on this feature also means that when the computer boots, it might lag some drivers that are loaded when it initially boots up. Thus, it might be the potential cause of the UNEXPECTED STORE EXCEPTION BSOD error. Thus, you need to disable Fast Start-up. To do that, follow these steps:
  • Boot your PC into Safe Mode.
  • Then tap the Win + R keys to open the Run dialog box.
  • Next, type in “control” to open Control Panel.
  • After that, select Hardware and Sound and click on Power Options.
  • Select “Choose what the power buttons do” from the left side menu pane and click on Change settings that are currently unavailable.
  • Afterward, uncheck the “Turn on fast startup (Recommended)” entry and click on Save Changes.
  • Now restart your PC for the changes to take effect and then check if the problem’s fixed afterward.

Option 6 – Disable your antivirus program

There are times when the antivirus program installed in your computer blocks file access and even disk access. Thus, disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 7 – Perform a Clean Boot

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the HAL INITIALIZATION FAILED error. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Increasing Virtual Memory
Hello and welcome to our Increasing Virtual Memory tutorial. Before trying to raise the quantity of virtual memory in your pc system, it's important to get a comprehension of its goal and use. This leads to the constant use of high-performing tasks in addition to keeping multitasking capability. The downside to this process is the fact that relatively, the HDD accesses information slower than a RAM module. Taking into consideration its use in a computer program and how virtual memory works, there isn't any amount of virtual memory allocation. The quantity of virtual memory to be defined for a unique computer program would be determined by the kinds of programs that are started and the quantity of multitasking done. The Microsoft Windows operating system yet does supply a recommended baseline memory based on the number of RAM installed and storage space of the HDD. Virtual memory allocation really indicates the upsurge in how big the paging file is. This file provides the pc program with all the essential instructions on the best way to act once all the installed RAM has been allotted to the running applications. In both Microsoft Windows XP (all variants) and Windows Vista environments, the method to control the paging file size is basically the same. To increase the quantity of virtual memory:
  • Click on the Start menu and choose the "Control Panel" alternative. When the Control Panel window is started, choose the "Operation and Maintenance" class.
  • Click on the "System" choice to create the Device Properties Window.
  • Click the "Advanced" tab and choose the "Settings" button under Operation. In the Operation alternative window, select the "Change" button under the Virtual Memory class.
  • Choose the hard disk where the Windows operating system is now installed. That can be the same place where in fact the paging file will be saved.
  • Test on the checkbox for the "Custom Size" to enable you to determine the number of virtual memory you need to use for your device.
  • Click the "OK" button thrice to shut all of the windows. Click the Start button and restart your machine to enable the upsurge in the number of virtual memory to be finished.
In establishing the number of virtual memory, you'll have to place a maximum value along with an initial. It is suggested that both values be equivalent in order to achieve the finest performance on your pc system.

Enable or disable Full-screen optimizations
In case you don’t know, there is a feature in Windows 10 computers that allows them to function a lot better. This feature is called Full-Screen optimization and it is enabled by default for several applications such as games and video players. If enabled, the Full-Screen optimization feature enhances the video playback and gaming by simply putting the CPU and GPU process as a priority. However, there are times when it can also result to a drop in the frame rate or FPS while in full-screen mode. And of course, the obvious solution to this dilemma is by disabling the Full-Screen optimization feature which is why Microsoft took action and removed this feature themselves in the recent Windows 10 Update releases. However, there is another way for you to enable it back or disable it yourself if you haven’t installed the recent updates yet and there are plenty of ways you can do both. All you have to do is follow the options given below carefully.

Option 1 – Try using Windows 10 Settings

If you haven’t installed the recent updates yet and all you have are the earlier releases, then this method would suit you.
  • Open the Windows 10 Settings app.
  • Next, navigate to System > Display > Graphics Settings or Advanced graphics settings.
  • From there, uncheck the “Enable Fullscreen optimization” option if you want to disable the feature, else just keep it checked.

Option 2 – Try using the Registry Editor

  • Tap the Win + R keys to open the Run dialog box and then type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Afterward, if a User Account Control or UAC prompt appears, click on Yes.
  • Once the Registry Editor is pulled up, navigate to this registry key: HKEY_CURRENT_USERSystemGameConfigStore
  • Next, right-click on Explorer and select New > DWORD (32-bit) Value and then name it to “GameDVR_DSEBehavior and tap Enter to save it.
  • Now double click on the newly created GameDVR_DSEBehavior DWORD and set its value to “2” if you want to disable it, or “0” if you want to enable it.
  • Once you entered the value, close the Registry Editor and restart your computer to successfully apply the changes made.

Option 3 – Try running the application in Compatibility Mode

If the first two options didn’t work, the next thing you can do is to run the application in a Compatibility Mode. Follow the steps below to do so:
  • Go to the location of the application or game on which you need to disable or enable the Full-Screen optimization feature.
  • After that, right-click on it and select Properties.
  • Next, switch to the Compatibility tab where you can see the “Disable fullscreen optimization” option to disable the feature and vice versa.
  • Now click on the Apply and OK buttons to apply the changes made in the application’s settings.

Outlook: We are unable to connect right now
If you are trying to start the Microsoft Outlook application on your Windows 10 computer but you suddenly receive a message box with an error message that says, “We are unable to connect right now, Please check your network and try again later”, read on as this post will guide you on how you can fix this error. This kind of error in Microsoft Outlook could be due to some issues with your internet connection or it could also be due to the VPN software if you’re using one. Whatever the cause is, there are several potential fixes you can check out to fix the error. You have to check your internet connection or try changing it. You could also try to disable your VPN software or restart your computer or Microsoft Outlook and try starting the app again. In addition, you can also try entering your password again or check some settings in the Windows Registry or open Microsoft Outlook in Safe Mode. Refer to the guidelines provided below to further troubleshoot the problem.

Option 1 – Try to check your internet connection

The first thing you can do to resolve the problem is to check your internet connection. You have to make sure that you are connected to the internet and that it has a stable connection.

Option 2 – Try to restart your computer or Microsoft Outlook and try again

The next thing you can do to fix the error is to restart your computer or Microsoft Outlook. This simple process can actually help you fix the problem as it could only be a glitch that can be fixed with a simple restart.

Option 3 – Try to enter your password again

You could also try entering your password again to resolve the error. Just click on the Cancel button to open a dialog box and then enter your password again and see if it helps. Note that you might have to do it for all your email IDs in Microsoft Outlook.

Option 4 – Try opening Microsoft Outlook in Safe Mode and disabling its add-ins

Putting Microsoft Outlook into Safe Mode can help you identify the problems in it. Safe Mode also helps you fix a certain issue caused by some corrupted add-in. To start your Microsoft Outlook in Safe Mode, refer to these steps:
  • Tap Win + R on your keyboard to open the Run dialog box.
  • Next, type in “Outlook /safe” and press Enter to run the command.
  • After that, it will ask you to select a profile that you want to use. Just simply select a profile from the drop-down menu and click on the OK button.
  • Now you have successfully opened Microsoft Outlook in Safe Mode. As a result, it will start with disabling the add-ins. Meaning to say, there is some corrupted add-in that’s causing the problem, and that you need to look for that add-in and either disable it or have it permanently removed.
  • Once you’ve identified the corrupted add-in, you can disable or remove it by going to File > Options > Add-ins. From there, select the option “COM Add-ins” from the drop-down menu and then click the Go button.
  • Finally, close Microsoft Outlook once you’ve covered the given steps above and then try to open it normally.

Option 5 – Try disabling the VPN

As pointed out earlier, if you are using VPN, this could be the reason why you’re getting the “We are unable to connect right now, Please check your network and try again later” error so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there.

Option 6 – Try to check the settings in the Registry

  • Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor.
  • Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesNlaSvcParametersInternet
  • From there, look for the DWORD named “EnableActiveProbing” and make sure that its value is set to “1”. When the value is set to 1, it means that it is Enabled. This is the default setting and is used to identify the status of the network connectivity of your computer.

10 Worst Computer Viruses in history
Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

viruses10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent. Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server. Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation. Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught. Wondering what makes the world’s most secure computers so safe? See the Tech@Work guide: Upgrade to the World's Most Secure and Manageable PC

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging. This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses. As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last. Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs. The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter. Need to up your remote work security game before there’s another entry on the list of most deadly computer viruses? See our guide: How to Work Remotely and Securely

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch. The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries. The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms. Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage. Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red. Can your printer get a virus? See our cool infographic: The State of Printer Security

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic. The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note. The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million. Where will cybersecurity go next? See our guide: The Future of Cybersecurity

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack. Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million. Other notable viruses The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years: Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove. Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India. Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably. Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather. Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries. Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.” Explorezip: This worm used fake emails to spread to every machine on thousands of local networks. Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million. Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs. Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates. Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

BubbleDock Complete Removal Tutorial

BubbleDock is a software developed by Nosibay. It installs a customizable dock at the top of your screen.

It adds registry entities to allow it to start automatically each time your system is rebooted, as well as installing an update checker that will automatically update the software when an update is available. The software also adds various scheduled tasks to start the application at different times, this ensures that once the application is closed, it is re-launched at a later time, making it very hard to keep the software closed permanently.

While the software is running, it will generate ad links in your browser, display sponsored ads, and collect personal information and deliver it back to it’s ad network. While using this software you may see additional ads, banners, links, pop-up ads, and various other sponsored content while browsing the internet.

About Potentially Unwanted Applications

Have you ever found out an unwanted program running on your computer system and wondered exactly how the heck it got there? A PUA / PUP (potentially unwanted application / potentially unwanted program) is actually a piece of software that comes bundled with freeware and you consent to install it on your computer. These are programs you certainly don’t want on your computer since it does not provide any beneficial service. From a technical standpoint, a PUP isn’t “true” malware. An interesting difference between PUP and malware is distribution. Malware is commonly dropped via vulnerability exploitation whereas PUP gets installed with the consent of the user, who purposefully or unwittingly authorizes the PUP installation on their PC. Although a PUP is not malware by definition, it can still be harmful software and put your computer at risk exactly the same way a computer virus does.

Exactly how do PUPs look like?

PUPs come in many forms; however, most of them are adware, which usually displays irritating adverts and advertising banners on internet pages that you’re surfing. PUPs which come as browser add-ons and toolbars are widely recognizable. These toolbars alter your homepage and your default search engine in the installed web browser, track your internet activities, modify your search results with re-directs and sponsored hyperlinks, and eventually slow down your internet browser and diminish your web browsing experience. Potentially Unwanted Programs occasionally act quite much like viruses or spyware. They will carry dialers, keyloggers, as well as other software built right into them that may monitor you or deliver your sensitive details to 3rd parties. Even if the PUPs are not basically malicious, these applications still do practically nothing good on your personal computer – they’ll take precious system resources, slow your PC, weaken your device’s security, and make your PC more susceptible to viruses.

Preventing PUPs

• Study the fine print to be sure the end-user license agreement (EULA) you are accepting is only for the program you actually intend to download. • Never accept standard, express, default, or other installation settings which are recommended. Always opt for custom installation. • Use a good anti-malware program. Try Safebytes Anti-Malware which will spot PUPs and handle them as malware by flagging them for deletion. • Avoid shareware or freeware wherever possible. Disable or get rid of toolbars and browser extensions you don’t actually need. • Don’t download software from popups, online advertising, file sharing sites, as well as other unreliable sources; look out for any pre-set, unwanted features when downloading the program. Avoid heading to blogs and websites that promote pirated programs.

How To Install Safebytes Anti-Malware On An Infected Computer

Practically all malware is inherently unsafe, but certain kinds of malicious software do a lot more damage to your computer than others. Certain malware goes to great lengths to prevent you from downloading or installing anything on your personal computer, particularly antivirus applications. So what should you do if malicious software keeps you from downloading or installing Anti-Malware? There are some solutions you could try to get around with this particular obstacle.

Install in Safe Mode with Networking

Safe Mode is a unique, simplified version of Microsoft Windows where only the bare minimum services are loaded to stop malware and other troublesome applications from loading. In the event, the malicious software is set to load immediately when the PC starts, switching to this mode can prevent it from doing so. In order to enter into Safe Mode or Safe Mode with Networking, press the F8 key while the PC is starting up or run MSCONFIG and look for the “Safe Boot” options under the “Boot” tab. After you restart the PC into Safe Mode with Networking, you may download, install, as well as update the anti-malware program from there. Now, you can run the anti-virus scan to remove computer viruses and malware without interference from another application.

Switch to some other internet browser

Web-based malware could be environment-specific, aiming for a particular internet browser or attacking specific versions of the web browser. If you’re not able to download the security software program using Internet Explorer, this means the virus may be targeting IE’s vulnerabilities. Here, you must switch over to a different browser like Firefox or Chrome to download Safebytes Anti-malware software.

Create a portable USB antivirus for removing viruses

Here’s yet another solution which is creating a portable USB antivirus software that can scan your computer for malware without needing installation. Abide by these steps to run the anti-virus on the affected computer. 1) Use another virus-free computer to download Safebytes Anti-Malware. 2) Plug the Flash drive into the clean computer. 3) Double-click the Setup icon of the antivirus software to run the Installation Wizard. 4) When asked, select the location of the USB drive as the place where you would like to put the software files. Follow the activation instructions. 5) Now, transfer the USB drive to the infected PC. 6) Double-click the antivirus program EXE file on the flash drive. 7) Hit the “Scan Now” button to start the virus scan.

Sometimes this can be a temporary error, so try restarting your PC. If the error is resolved then that’s great. However, if it still persists, then try other solutions.

2) Change the Boot Order

The underlying cause for the Hal.dll error is often not properly configured BIOS; if this is the cause, simply change the boot order of the bootable devices like your hard drive.

Another way to resolve is to update the volume boot code to use BOOTMGR. To do this, access advanced startup options, open the command prompt and type bootsect command and then press Enter. Run the command and then you’ll get the following message: C: (\?Volume{37a450c8-2331-11e0-9019-806e6f6e6963}) Successfully updated NTFS filesystem bootcode. Bootcode was successfully updated on all targeted volumes. After that close the command prompt. This is most likely to resolve the error.
