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.

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.

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.

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.

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.

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.

Remove or join a Domain from Windows

As you know, networks that are domain-based are common in organizations and companies. These domain-based networks require multiple computers to be controlled through a single node known as a server. And the one that sets certain policies and restrictions on every system that is joined to the domain is the server administrator. So if you want to add your computer to a domain, you need to have the following information available:

The domain name
A user account name that’s registered in the active directory associated with the server
Windows Enterprise, Pro, or education version

In this post, you will be guided on how you can join or remove a domain. To get started, follow the given instructions below.

Option 1 – Joining a domain

First, you need to connect your computer to the network associated with the server since your computer and the server have to be on the same network.
Next, click the Start button and then click on the gear-like icon for Settings to open it.
After that, navigate to this path: Accounts > Access work or school.
Then click on Connect. This will open a new dialog box and from there, select the “Join this device to a local Active Directory domain” option.
Afterward, you will be asked to enter the username and password of your domain account.
Now select your Account type and when you proceed, you have to restart your computer. Your domain account should now be created.

Option 2 – Removing a domain

You need to open the Windows 10 Settings app.
And from there, go to this path: Accounts > Access work and school.
Next, select the account you want to remove from the domain and then click on Disconnect.
A prompt will then appear that says, “Are you sure you want to remove this account? This will remove your access to resources like email, apps, network, and all content associated with it. Your organization might also remove some data stored on this device”. Just click on Yes.
This will give you a Disconnect from the organization prompt.
Now click on Disconnect and select Restart now to restart your computer. This will complete the removal process of the domain.

Personalize Windows 11 Start menu

Windows 11 is released and its adoption goes slower than Microsoft would like but nevertheless, it is slowly getting adopted, especially among new computers. Windows 11 has brought us a new modern look of OS but if you would like to personalize it a little more you can. Follow the guide on various things that you can change inside Windows 11.

Personalize list of recently added apps, opened items, folders

The recommended section that shows recently added apps and recently open items can be turned off and hidden now to be shown. In order to do this follow these steps:

Open Windows Settings by pressing WINDOWS + I
Click on personalization in the sidebar
Click on START and go through the options
Turn OFF switch beside recently accessed files
Additionally, you can also change which folders appear on the Start menu.

Remove apps or change app order on the Start Menu

To remove application not to be shown in the Start menu at all follow this simple guide:

Right-click on app
Choose unpin
To place the application on Start click on All Apps, right-click on the app and choose Pin to Start
To drag and rearrange apps, simply click on them and drag them to the new place.

Change the Start Menu location

When Windows 11 was first released Start Menu could only be located in the middle of the screen but thanks to plenty of backlash from users now it is possible to move it on a more traditional left side.

Press WINDOWS + I to open the settings app
Click on Personalization
Look for taskbar behaviors
Inside taskbar behaviors look for Taskbar alignment
Change alignment to left

Change the Start Menu color

In order to change the color of the Start Menu follow the next steps:

Open Settings app
Go to personalization settings
Go to Colors
Switch to custom
Under accent color pick a color you like or make your custom one.

Fix Windows Activation Error 0xC004F211

If you got an Activation Error 0xC004F211 after having installed or upgraded your Windows 10 PC, then this indicates that some hardware in your computer has changed which’s causing the error to pop up. Windows might not be able to determine if the key is used on a new computer or if it’s still the same one if you have just removed or upgraded old hardware. But worry not for this post will guide you in fixing the Windows Activation Error 0xC004F211 on your Windows 10 computer. When you encounter this error, you will see the following error message on your screen:

“Cannot activate Windows 10. Try activating again later. If that doesn’t work, contact support. Error code: 0xC004F211.”

Note that although hardware changes cause this error, the minor ones don’t really cause any issues with activation, however, if you have made any significant hardware change such as replacing your motherboard, it will most likely cause the activation error. In such cases, the Windows Activation system will treat this as new hardware and you will need a new license for that. Even if your Windows 10 computer has a genuine key, it might still fail to get activated which results in the Windows Activation Error 0xC004F211. Thus, before you do other troubleshooting steps, you need to run the Windows 10 Activation Troubleshooter first. To do so, follow these steps:

Go to Settings and then select Activation.
After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

In addition, there is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
From there, go to Activation and select the “Go to Microsoft Store” option.
After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
Now update your Windows 10 computer using the new key and it should automatically activate your computer.
Next, you have to create a Microsoft account or connect your existing local account to your online account.
Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

The current state of Government vs BigTech

BigTech platforms Google and Facebook were hit with a series of antitrust lawsuits by the US federal government and states on charges they are operating monopolies and abusing their power. Below is the status of the cases, as well as government probes of Apple and Amazon in their current states

Two lawsuits against Facebook

In a defeat, Judge James Boasberg said the Federal Trade Commission, which had sued Facebook in December asking that Facebook be forced to sell WhatsApp and Instagram, failed to show that Facebook had monopoly power in the social-networking market, among other problems. However, the FTC could file a new complaint by July 29. He threw out a related state lawsuit entirely, saying that the attorney's general had waited too long. They are looking at their options.

Four lawsuits against Google

The US Justice Department sued Google in October, accusing the $1 trillion company of illegally using its market muscle to hobble rivals. A trial date was set for September 12, 2023. A lawsuit by 38 US states and territories accuses Google of abusing its market power to try to make its search engine as dominant inside cars, TVs, and speakers as it is in phones. This was consolidated with the federal lawsuit for purposes of discovery. Texas, backed by other states, filed a separate lawsuit against Google, accusing it of breaking antitrust law in how it runs its online advertising business. Dozens of state attorneys general sued Google on July 7, alleging that it bought off competitors and used restrictive contracts to unlawfully maintain a monopoly for its app store on Android phones.

Justice Department investigates Apple

This probe, revealed in June 2019, appears to focus on Apple's app store. Some app developers have accused Apple of introducing new products very similar to existing apps created by other developers and sold in the Apple Store, and then trying to banish the older apps from the store because they compete with Apple's new product. Apple says it seeks to have only the highest-quality apps in the app store.

Justice Department probing Facebook and Amazon

In July 2019, the Justice Department said it was expanding its Big Tech probes to include "search, social media, and some retail services online", an apparent reference to Facebook and Amazon.

Federal Trade Commission on Amazon

In its investigation of Amazon, the FTC is likely looking at the inherent conflict of interest of Amazon competing with small sellers on its marketplace platform, including allegations that it used information from sellers on its platform to decide what products it would introduce.

Razer Huntsman V2 mechanical keyboard

When it comes to computer peripherals first thing that comes to people's minds is probably Mouse and Keyboard. Also when discussing peripherals brands, Razer is not a stranger and over the years it has built its name and cult following. Razer’s mechanical keyboards have been always in the upper field of quality and trust from users and Huntsman is no different.

Tech specifics of Huntsman keyboard

Mechanical optical switches Razer has introduced their new optical technology switch with this keyboard. These switches are faster and more accurate than typical mechanical switches and if tests are to be believed this is the fastest keyboard currently on the market.
Multi-functional digital dial A multi-function digital dial with three tactile media keys gives you instant access to everything from brightness to volume in seconds. All programmable and customizable through Synapse 3, so you can set your preferred configurations right at your fingertips.
10-key rollover Anti-ghosting technology that enables 10-key simultaneous presses at the same time
4-side underglow with Razer chroma Go crazy and personalize lighting effects any way you want with a full 4-side underglow and 38 customization zones. Powered by Razer Chroma

Feel and noise

In the department of noise, well it is the mechanical keyboard so naturally, it will be louder than membrane ones but in terms of comparing it to other mechanical keyboards it is within the same noise range, maybe just a tiny bit silenced. The keyboard comes with 2 different types of switches, purple clicky ones that are louder and have that *click* sound for sound feedback, and red ones, that are not equipped with clicky sound but are linear providing slightly faster performance. If you choose the Huntsman elite model of the keyboard it will come with a nice hand resting mat that is very comfortable and feels right. Using a keyboard feels like using a Razer keyboard, it is responsive and gives that superior mechanical feeling.

Conclusion

Razer Huntsman mechanical keyboard is not the cheapest nor the best on the market but it is the fastest one out. It is in the top tier of keyboards and worth the investment.

DownSpeedTest Removal Guide

DownSpeedTest is a Browser Toolbar Extension for Google Chrome that allows users to test their internet speed and convert files, however this speed test does not show proper values, nor even close.

Upon installation DownSpeedTest will replace your default New Tab page with its own Search Engine “MyWay.com” or “Search.MyWay.com”. This Search Engine camouflages itself as a “Enhanced Google Search Engine”, but all it does is allow more room for easier ad injection. In the background, this extension monitors user browsing behavior and records visited links, viewed products, clicked links and time spend on websites. This information is later used for Ad targeting.

While browsing the internet with this extension enabled you will experience additional ads, sponsored content, and even pop-up ads on some occasions. Due to its information mining behavior and aggressive ad placement, DownSpeedTest had been marked as a Browser Hijacker and it is recommended for removal.

About Browser Hijackers

Browser hijacking is a type of unwanted program, commonly a web browser add-on or extension, which causes modifications in the browser’s settings. There are lots of reasons why you may experience a browser hijack; but commercial, advertising and marketing are the major reasons for their creation. These are typically used to force hits to a specific site, manipulating web-traffic to generate ad-revenue. Even though it might appear naive, these tools are made by malicious people who always try to take full advantage of you, so that hackers could earn money from your naive and distraction. In a worst-case scenario, your browser could be hi-jacked to download malicious software that can do a lot of damage to your laptop or computer.

How one can know whether the browser is hijacked?

When your web browser is hijacked, the following might happen: your browser’s homepage has been reset to some unknown webpage; new bookmarks pointing to porn websites have been added to your bookmarks; the default browser configurations are modified and/or your default web engine is altered; you see unwanted new toolbars added; unstoppable flurries of pop-up ads show up on your computer screen; your browser gets slow, buggy, crashes regularly; you can’t navigate to specific internet pages, such as security software related websites.

How does a browser hijacker infect a computer?

Browser hijackers infect computers via malicious e-mail attachments, downloaded infected documents or by visiting infected internet sites. They can be included with toolbars, add-ons, BHO, plugins or browser extensions. Also, some freeware and shareware can put the hijacker in your PC through “bundling”. Browser hijackers could record user keystrokes to collect potentially important information leading to privacy concerns, cause instability on computers, significantly disrupt user’s browsing experience, and ultimately slow down the system to a point where it becomes unusable.

How you can fix a browser hijack

One thing you could try to eradicate a browser hijacker is to find the malware in the “Add or Remove Programs” list of the Microsoft Windows Control Panel. It might or might not be there. When it is, uninstall it. However, most browser hijackers are difficult to eliminate manually. Regardless of how much you attempt to get rid of it, it might come back over and over. Amateur PC users should never try for the manual form of removal methods, since it demands in-depth system knowledge to perform fixes on the system registry and HOSTS file. Anti-malware software is really effective when it comes to picking up and eliminating browser hijackers that regular anti-virus application has overlooked. If you’d like to get rid of persistent hijackers effectively, install the top-rated Anti-Malware software Safebytes Anti-Malware. Use a system optimizer (like Total System Care) along with your anti-malware software to fix various registry issues, remove system vulnerabilities, and improve your computer performance.

What To Do If You Cannot Install Any Anti-Malware?

Practically all malware is bad and the consequences of the damage could differ according to the specific kind of malicious software. Some malware is created to interfere with or block things that you’d like to do on your PC. It may not permit you to download anything from the web or prevent you from accessing a few or all of the internet sites, especially the anti-malware websites. So what you should do if malware prevents you from downloading or installing Anti-Malware? There are a few actions you can take to circumvent this problem.

Install the anti-virus in Safe Mode

Safe Mode is a unique, simplified version of Microsoft Windows in which only essential services are loaded to counteract viruses and also other problematic applications from loading. If the malware is set to load immediately when computer starts, switching into this mode may prevent it from doing so. To start the computer into Safe Mode, press the “F8” key on the keyboard just before the Windows logo screen shows up; Or after normal Windows boot up, run MSConfig, look over “Safe Boot” under the Boot tab, and then click Apply. Once you are in Safe Mode, you can try to install your antivirus application without the hindrance of the malicious software. Following installation, run the malware scanner to get rid of most standard infections.

Download the anti-malware program using a different browser

Web-based malware could be environment-specific, aiming for a particular web browser or attacking particular versions of the browser. If you’re not able to download the security program using Internet Explorer, it means virus is targeting IE’s vulnerabilities. Here, you should switch over to an alternative web browser such as Chrome or Firefox to download Safebytes Anti-malware software.

Install anti-malware on a thumb drive

Another solution is to save and operate antivirus software tool completely from a Pen drive. Follow these steps to use a USB flash drive to clean your infected PC. 1) Make use of another virus-free computer to download Safebytes Anti-Malware. 2) Insert the USB drive on the same system. 3) Double click on the downloaded file to run the installation wizard. 4) Choose the USB flash drive as the location for saving the software file. Follow the instructions to complete the installation process. 5) Now, plug the USB drive into the corrupted computer. 6) Double-click the Safebytes Anti-malware icon on the pen drive to run the application. 7) Run Full System Scan to identify and clean-up of all types of malware.

Disable Telemetry & Data Collection in Windows

The Windows 10 Telemetry and Data Collection features are auto-enabled and they collect all sorts of user activity and sends it to Microsoft. Microsoft says that the data collected only enhances the overall user experience and Windows functionality better but the number of data breaches happening across the globe has forced users to be extra cautious about their data privacy. So naturally, from stronger passwords and other services management, it is only logical to turn off Windows data gathering. To do so:

Press ⊞ WINDOWS + R to open the run dialog.
In the Run dialog type: taskschd.msc
Press CTRL + SHIFT + ENTER key combo to open Task Scheduler in admin mode.
On the left pane, navigate to the: Task Scheduler Library > Microsoft > Windows > Customer Experience Improvement Program
At the location, on the middle pane, right-click on the task named Consolidator and select Disable from the context menu...
Repeat the process with all other tasks listed in the middle pane.
Exit Task Scheduler.

Fix 0x8000ffff error in Windows 11

Error 0x8000ffff prevents you from using the Microsoft store. Altho it is not a critical error that will break Windows, it is annoying enough that will require fixing so we can use the store once again and install apps when we want to.

Malware Guide: How to Remove Solimba

What is Solimba?

Solimba is a bundled executable program. It was created to be launched as a promotional tool to get advertisements loaded on a user’s system, upon installation. As a bundle, Solimba offers installation of various programs, with the objective of promoting various products and services. It utilizes unethical techniques, as in the case with adware tactics to influence or for want of a better word, hijack an Internet Browser to affect a website’s result on a search results page. In this assessment, Solimba distributed ads on Internet Explorer, Chrome, and Mozilla browsers, by hijacking various Internet Browsers to change the user's experience. (Images are shown below) Technical details about Solimba PUP include:

Digital Signature: POPELER SYSTEM, S.L. Entry Point: 0x0000C1DC

Assessment of Solimba Potentially Unwanted Program

Solimba PUP is all about the ads. Once this executable is installed, it penetrates your computer system and sends ads all over your Internet Browser – Chrome, Internet Explorer, Mozilla Firefox, and the likes. For this assessment of Solimba.exe PUP, two installations were carried through. In layman's terms, I actually installed Solimba on two occasions to decipher the true nature of the PUP. It was shocking to find that both installations revealed different bundled programs and advertisements. In the first instance (as shown below), Solimba proved more aggressive in featuring ads for revenue advancements.

Solimba employed aggressive advertising techniques

It’s important to note that hijacked results resulting from the installation of Solimba. This affected the results of the website on the Internet browser to boost its ranking, even without the use of a search engine. The advertisement displayed on the Internet Explorer search page routes the user to a software installation website. The utility tool in question was a “Windows 8.1 PC Repair” tool used to identify threats present on the Windows 8.1 OS. The advertisement displayed on the Chrome Browser search page routes the user to a health and beauty magazine website. This site advocates health and beauty, especially issues concerning weight loss. Several ads were visible on-site, displaying products to assist people in losing weight. During my installation of Solimba, the installation wizard underscored that four programs would be downloaded. These programs included N8Fanclub.com_KinoniRemoteDesktop, Lolliscan, PaceItUp, and SearchProtect. Interestingly, only two programs from the list were apparent or obvious. An N8Fanclub.com_KinoniRemoteDesktop file was made on the Desktop and SearchProtect was seen in “All Programs”, along with files stored on the computer’s Local Drive. The other programs that were “supposedly” installed remained concealed. A test was done to determine whether these were counted as extensions or add-ons to the varying web browsers but nothing was found on any of the tested browsers – Google Chrome, Internet Explorer, and Mozilla Firefox.

Description of 4 Installed Files

N8Fanclub.com_KinoniRemoteDesktop

When this file was initially found on the Desktop, a rootkit came to mind. A rootkit was used as a means to an end. Whoever was on the receiving end of this unwanted file would be able to connect to an infiltrated system without the knowledge of the user. After running the file to determine its behavior, nothing much happened. A message appeared indicating that the software couldn’t execute on the computer. That was pretty tricky since, to begin with, I didn’t place that specific file on the desktop but it came along with the territory and so I had to accept it. Further research online into N8Fanclub.com_KinoniRemoteDesktop proved very rewarding. A search of the entire file name was not able to do the trick so I had to do research on both terms separately. After landing on N8Fanclub.com, I was nicely asked to disable my adblocker. There seemed nothing harmful about the site. However, due to the fact that it was not what I initially installed, the program was an unwanted program. That’s exactly what Solimba does. It installs several other programs that were not requested by the user in an attempt to make money from advertising. The mere fact that this program got installed meant that it was to promote an online service.

KinoniRemoteDesktop

was a separate program. It was combined with N8Fanclub as a way to allow users to use their PC computer “as if they were sitting in front of it.” A user would be able to make use of a full web browser, watch Flash videos, play games, and even use office applications. This would be done from the user’s Nokia device. This is an advertisement at its best.

Lolliscan

This program did not allow me to see much since it didn’t leave a physical trace behind. However, during the installation, Lolliscan was listed as one of the four programs that would be installed. Overall, Lolliscan supposedly should be able to save people money since this form of the ad focuses on showing coupons when visiting sites such as Amazon. While this seems like a good deal, this ad will invade your personal space and distribute pop-ups at the most inopportune times.

PaceItUp

As the name states, PaceItUp is software added to a browser with the intent to speed your computer. Quite the contrary, PaceItUp does the total opposite since it installs bundled programs that slow down a computer system. PaceItUp is also known for displaying ads and tracking what the user does on his/her computer system.

SearchProtect

It’s known for hijacking your computer’s homepage. In fact, this addition is very stubborn and often possesses a challenge when a request to uninstall is made.

Further Information on Solimba

The second installation of Solimba also had its own dose of bundles to display. In comparison to the first installation, two programs from the bundle were different while two remained the same. two additional programs were installed along with the second installation of this bundle. These were dubbed Optimizer Pro and GamesDesktop. SearchProtect and N8Fanclub.com_KinoniRemoteDesktop remained triumphant and unbeatable. They were repeated within the installation.
