How to remove myBrowser

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.

10 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?

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?

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.

Windows 11 is coming soon, from its typical view and color scheme, Windows 11 will natively support dark mode. The dark mode is very popular in many applications today, some large companies like Adobe, Autodesk, and many more have already adopted a dark color scheme for their software so it is logical for others to follow and Microsoft is aboard for it. The dark mode itself has its benefits, for people who work on computer for longer period of time dark mode inside applications will throw less white and blue light on their eyes making workhours easier and pleasant on them. As a person who does indeed spend a lot of time in front of the screen, I would advise you to switch to dark mode regardless of the time that you spend with a computer, your eyes will be grateful.

Switching to Dark mode in Windows 11

1. Open Windows 11 Settings by pressing ⊞ WINDOWS + I
2. Click on Personalization on the left sidebar
3. On the right side click on Color
4. In color options click on the drop-down menu right next to Choose your color
5. Select Dark

Your choice will be applied right away and you can safely close settings.

If you have been using Windows for quite some time now then you’re probably aware of the BIOS or UEFI password. This password lock is the one that ensures you enter the set password even before your Windows PC boots up. However, there’s just one downside with the BIOS or UEFI password – there is no recovery option, unlike your Microsoft account. Worry not though for this post will guide you on how you can set or recover a BIOS or UEFI password on your Windows computer. The BIOS or UEFI passwords are stored at the hardware level which means that unless the OEM wants or has configured a way to recover the password, it is pretty much impossible to reset it. There are times when they are so strict that the only way to get through it by contacting customer care. Note that any Windows computer with this lock can’t be unlocked by trying to reinstall Windows. In this post, you’re going to have to remove the CMOS battery temporarily, clear unknown BIOS/UEFI passwords using the bios-PW website as well as call customer care. For more details, refer to the options provided below.

Option 1 – Remove the CMOS battery temporarily

In case you didn’t know, every motherboard comes with a CMOS battery which helps the computer system to keep the clock ticking and in making sure that the BIOS settings are not lost when the computer is powered down. Every time a computer is turned on, the CMOS battery ensures that the information is available for the computer to boot up. So when you remove the CMOS battery temporarily, say about 30 seconds or a minute, the settings will be lost. There are some motherboards that are built-in ways that when you remove the battery for long, it will reset everything including the password for the BIOS or UEFI.

Option 2 – Clear the unknown BIOS or UEFI passwords using a bios-PW website

If the first option didn’t work, you can try using this BIOS Password website at http://bios-pw.org/ to clear the password.

• When prompted by the BIOS, enter the wrong password a couple of times as doing so will lock you out of the system.
• After that, you will see a new number or code on the screen which will include a message about System Disabled [XXXXX] Service TAG [YYYYY].
• Next, open the BIOS Password website and enter the XXXXX code in it and make sure to tap the Shift + Enter keys or just enter.
• Now it will open multiple unlock keys which you can use to clear out the BIOS or UEFI lock on your Windows PC.

Option 3 – Call the customer care

If the second option still didn’t work, you have to call customer care and follow their suggestions for they will walk you through fixing the problem using the service tag or might suggest that you visit a service center to make things easier for you. Note: You also have the option to set a BIOS or UEFI password. Although it isn’t recommended, you still can do it if you really want to. Remember that the BIOS or UEFI interface varies from OEM to OEM so you must find something related to either PASSWORD or SECURITY. You will have the following similar options:

• Supervisor password – it’s the same as the master password that can change important system settings.
• User password – with this password, any user can change minor settings.
• Master password – you can use this password for a hard drive or as a general password.

There are several OEMs that offer micro-control where you have to enter the BIOS password. For instance, you’ll have the option to skip for a normal restart, or when you select a boot device while you might have to enter the password for unattended reboots or when your PC is powered on, etc. And if you are here to remove the password, you need to find a remove password option in the same section. You will be prompted to enter the set password once and if it’s correct, it will remove the BIOS password. After that, you have to save and exit the BIOS then restart your computer and check if the settings are properly applied.

Did you know you can use emoji in file names inside Windows 10? It is no secret that emojis are basically everywhere and Microsoft has seen this and integrated them into Windows itself, so you can name files using emojis or combine them with text. Placing emojis in file names or in the text is extremely easy, all you have to do is press ⊞ WINDOWS + . and the emoji dialog will open from where you can find which emoji you would like to use. And that's it, you just used emoji for the file naming.

!!!NOTE!!!

In theory, some applications may not like these emojis if they don’t support Unicode characters. However, modern applications are designed to work with a broad set of languages that should properly support emojis. For example, the classic Windows Command Prompt can’t see emoji characters in file names properly, but both PowerShell and Microsoft’s new Windows Terminal can display them properly. If you do run into a problem, you can always open File Explorer and rename the affected files and folders to remove the emoji characters. You can then use those files in applications that don’t properly support emoji file names.

If you suddenly encountered an error saying, “The application failed to initialize properly (0xc0000005)” when you are using an application on your Windows 10 computer, read on as this post will provide you some potential fixes that could help you fix the error.

If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such an issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has virtualization support, the best thing you can do now is to fix this black screen issue. There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.

Option 1 – Try to disable Hyper-V

Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third-party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:

• In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
• Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
• Click the OK button and then restart your computer.
• Now try to use VirtualBox again and see if the problem is fixed.

Option 2 – Try to disable 3D Acceleration

The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:

• Open VirtualBox on your computer and select the virtual machine.
• Next, click on the Settings button and go to the Display section.
• After that, look for a checkbox named “Enable 3D Acceleration” located on your right-hand side and then uncheck it.
• Save the changes you’ve made and reboot your PC and see if you can now run the virtual machine without any problem.

If the Diagnostic Data level in your Windows 10 computer is configured manually to the non-default security setting of zero and you’ve encountered an error code of 0xc0000005, read on as this post will guide you in fixing the problem with the Remote Access Connection Manager Service.
