But you don’t need to worry about it as VPN.com is here to shed light on what all these different kinds of internet infections do, how they can locate you, and what preventive measures you can take to stop them if they have already penetrated. So, continue reading our guide to find out everything you need to know about malware and more!

Malware

Malware is a generic phrase that includes all types of vicious software such as worms, viruses, ransomware, Trojans, and spyware. These programs are intended to affect and damage computers, swipe sensitive data, or take over a system. In 2022, up to 75% of organizations have experienced malware activities that extend between employees which is highest in the past few years.  

Once malware accesses a system, not only the affected device is at risk but all other devices working on the same network can be in danger too. In virtue of simplicity, we will primarily use computers as examples, yet it’s significant to be aware of the fact that malware can affect all types of digital devices such as mobile devices, desktops, and other Internet of Things (IoT) gadgets.

Research by SonicWall Capture Labs declared that there is an 11% increase in malware attacks in the first six months of 2022 as compared to 2021, counting almost 2.8 billion attacks worldwide. Moreover, in 2022, 35% of suspects blamed substandard preparation when they faced business-disrupting cyberattacks. That’s why it’s important to take measures to protect your device by establishing proper malware protection and identifying the signs of an infected system.

How Does Malware Affect a Computer?

How Does Malware Affect a Computer

Malware can infect a computer in different ways, such as email attachments, interrupted software downloads, and websites. The following are some common ways malware can infect your computer. 

Malicious and jeopardized web pages

Have you ever heard about a malicious web page? It’s a web page that has been created to infect your computer with malware. Such pages are made by cybercriminals or can be the aftereffect of a website being jeopardized (otherwise referred to as being hacked).

If you visit malicious web pages, click on affected links, or download any files from them, they will infect your computer. However, the most common way by which cyber criminals make the victims visit malicious web pages is to deliver a mass fraction of false emails, generally called phishing emails.

Identifying Vicious Web Pages

The best method to avoid falling victim to a malware attack is to become aware of how to perceive a malicious web page. Here are a few suggestive signs that a web page can be pernicious.  

Initially, pay heed to the URL of the website: a false link may look unusual, and different from a legal domain that it pretends to be. Similarly, the most obvious examples might contain false spellings of famous websites, so always be cautious.

Redirect links can probably be highly operational malicious links, as these are the links that seem normal, but redirect to a fake website. It’s not difficult to recognize a rechannel link by investigating its final destination, using digital tools. 

Secondly, you might find a page strange when you realize that there is only little or no content on it. Other signs of a tricked web page are spelling and grammar errors. But be careful as some malicious websites may look similar to their legal match. 

Thirdly, the web page may support services or products that look too good to be genuine. Check-ins appear at intervals, sometimes so frequently that it makes navigating a page a horrible dream, also indicating that the page can be wicked. If you witness any of these indicators, it’s best to leave the page immediately. To be ultra-secure, you can also clean your browser’s cache and cookies. 

Phishing and Spear Phishing Emails

A general approach that cyber criminals utilize to infect their targeted computer system is sending phishing emails. Do you have any idea what a phishing email is? It’s a social engineering cyberattack that is intended to mislead victims into giving their confidential information, such as credit card numbers, or login credentials. Cybercriminals often try to represent a legal firm or individual just to win the victim’s trust.

An example of a phishing email would be an email that seems to be from a high-tech company presenting that there is some sort of problem with your account and asking you to click on a link where you can set up the new security update. But this comes out to be a malicious link that accelerates to a malware-infected website. A phishing email may also ask the user to go through an attached signup form which will act and infect the user’s machine with malware on downloading. 

Spear phishing is a severe version of phishing in which cybercriminals do thorough research and attack a particular individual or organization. They often utilize personal information about the victim like their name, job post, or interests to make the email more reliable. An illustration of spear phishing would be an email that seems to be sent by your head asking you to upgrade your personal information on a malware-infected software or website. 

Identifying Phishing Emails

Phishing emails can be hard to detect as they often seem legal. But there are some suggestive signs that an email is a scam. First of all, check the sender’s email address. A phishing email will often have a fake or tricked address identical to a lawful address. Secondly, check for mistakes or grammatical errors in the main text of the email. These can be signs that the email has not come from a legal source.

Similarly, be careful of any emails that represent a sense of emergency or want you to take quick action. For instance, clicking on a link. Last but not least, an email that asks you for your personal data like your credit card number or your login information is a telltale sign of a phishing email. 

A typical phishing email analogy is that of the Nigerian prince who wants to transfer his wealth out of the country. Such emails often want your bank account details so that they can manage the transfer to your account. But it’s nothing but a fraud. 

Spear phishing emails are very hard to identify as they can be very customized. However, if you receive an email by the name of your relative and the person is asking for money, always be doubtful. If you are not sure about the email, it’s always better to play it safe and don’t click on any links or open any files. If the email seems to come from a legal source such as from your manager or a company you do business with, it’s good to contact them directly to verify that the email is legal. 

Infected Removable Devices

Another, less prevalent form of infecting a system with malware is by depending on an unknown person to connect an infected external drive to your device. Sometimes cybercriminals will leave an infected USB in a public forum so that someone might pick it up or connect to their computer carelessly. 

Malware will enter your device automatically when the infected drive is installed in your system. So, don’t use a removable drive that is not in your possession.

How can I Identify and Fight Against a Malware Attack? 

How can I Identify and Fight Against a Malware Attack

Now you better understand why malware attacks are so dangerous for your website. It’s time to understand how you can detect malware and how to remove it from your operating system. 

Malware Prohibition

The first step to avoid any type of malware is always prevention. Cybercriminals can only target your system if you allow them to do so. So, the only way to stop malware is to never let it run on a system right from the start.

The simplest method to keep your system safe is by regularly installing security updates on your operating system and software. Moreover, it’s better to install an effective external antivirus scanner and program and make sure that these programs are updated with the most recent malware definitions. 

Malware Detection

Normally, the most efficient way to recognize malware is with the help of tools that are made to scan your system with the familiar indicators of malicious code. Such signature-based identification techniques are not reliable because malware can transform its code to avoid detection. Eventually, one of the ultimate stages of defense is the ability of the user to detect peculiar behavior. There is no doubt that different malware types will often show their own unique traits. We will explain the revealing signs of the three main types of malware below:

  • Spyware
  • Adware
  • Ransomware

Malware Removal

If you think that your device is already infected with malware, the first measure you should take is to disconnect the internet of the infected device to prevent excessive damage. Secondly, scan your entire system with your antivirus program and eliminate any type of malware detected. If you don’t know how to do this, you can easily find guides on how to run your specific antivirus program. Finally, change the passwords that you think are compromised and try to contact an expert for support.

Adware

Have you ever heard of adware before? It’s some kind of malicious software that installs itself privately on your device and shows unnecessary pop-ups and advertisements. In some specific situations, adware can even trace your online activity and display chosen ads.

Adware is an acronym for advertising-supported software, intended to cast advertisements on your screen, most probably with a web browser. Some security specialists declare it the progenitor of the modern-day PUP (potentially undesirable program). Generally, it uses a tricked method to either present itself as legal or jack another program up to fool you into installing it on your PC, tablet, or mobile device. 

We will tell you how it actually happens. When you normally search online with your smooth, well-behaved browser, only to see it going into a virtual outburst of advertisements either slides in the side, pop-ups, or otherwise interfere in your research and re-channel your planned activity. And it doesn’t matter how much you try to close that window, they keep irritating you like flies at a picnic spot.

How Can I Detect and Respond to an Adware Attack?

How Can I Detect and Respond to an Adware Attack

As Adware is a very annoying virus, you should know how to detect it and remove it from your system in the first place. Here is an explanation of how you can recognize and respond to an Adware attack. 

Adware prevention

You should take some preventive measures and practice safe computing. We suggest you think twice before installing or downloading any new software – specifically freeware. Review the mentioned terms and conditions like a lawyer before approving them and cease the download process if anything feels like an authorization to load adware.

Avoid couponing sites, and unlawful downloads, and never tend to open an app from a strange source, even if it comes to you with the name of a known email contact. 

Ultimately, prior to all these above precautions, don’t forget to download a worthy cybersecurity program for your PC or mobile phone. Execute scans regularly, and keep the security updates, right, and up-to-date. You can also buy anti-malware products as a preventive measure.

Different anti-malware products are available in the market according to different operating systems like Malwarebytes for Mac, Malwarebytes for Chromebook, Malwarebytes for Windows, Malwarebytes for iOS, and Malwarebytes for Android. By equipping yourself with wisdom and protecting your device with a powerful cybersecurity program, you can take measures for adware-free browsing online. 

Adware Detection

Detecting the Adware attack is not a hard nut to crack as there are a few suggestive signs that tell whether there is adware running on your system or not.

  • The homepage of your web browser has unaccountably altered without your permission.
  • Your web browser has responded lately to a crawl.
  • Ads appear in the sections where they should not be. 
  • Web pages that you visit frequently are not working properly.
  • Website links divert you to pages unfamiliar from what you expected. 
  • Your Mac device starts installing undesired software applications.
  • New extensions, plugins, or toolbars start popping up on your browser.
  • Your browser crashes. 

Adware Removal

If you doubt adware has jeopardized your Windows PC or Mac, there are some measures that you can take to eliminate the infection. Primarily, back up on your files, regularly. You can try to eliminate the adware through the relevant service on your operating system (that is Remove/Add on the Windows). But it demands you to identify the adware program’s name, or that the adware doesn’t have a reviver, which are files created to close a program after an uninstall. 

If that is the situation, then install a legal cybersecurity program that is mostly free to try and is made to search and destroy adware, PUPs, and any new malware types hiding on the scene. Execute a scan and if there is any suspicious content hiding away in your device, it will pack, mark, and discard them for you. At this stage, it’s better to change your password, not only of your Mac device but your email, your desired shopping stores, your social media accounts, and your online billing centers. 

Examples of Adware

Following are some examples of Adware that are intended to compromise your system. 

Lawful adware that lets you approve ads and software promos, compensating developer costs so they can provide their software for free. Users readily download this type of adware to grab a free product. 

Potentially Unwanted Applications (PUAs) involve any program you might have selected to download on your device. These may also be known as potentially unwanted programs (PUPs). PUA adware merges into the gray area, where the limit to which it is unlawful or malicious, counts on the goals of the software and those who spread it. 

  • Legal abusive adware PUA is made to assist you with ads. Excessive ads may be present in the adware itself or in packaged software in the form of browser toolbars or other methods. 
  • Legal deceptive adware PUA may forcefully make it complex to initiate installing harmless third-party software. 

Illegal malicious adware PUA takes advantage of vicious third parties who want to spread malicious software like viruses, spyware, or other malware on your device. 

Spyware

Spyware is also a very common type of malware that observes your computer’s activities. Once the spyware enters a system, it starts sneaking into the activity of that device, breaching sensitive information such as passwords and internet activity like social media accounts, site visits, and even finance records.

A few spyware are powerful enough to take control of specific features of the affected system. For instance, a webcam or microphone, to record video and audio footage without the user’s permission.

This confidential information is then transferred to the cybercriminal who is behind this wicked scene. Do you know that since 2017, the detection of business malware has increased by 79%, and most of these malware attacks have their roots in information-stealing programs such as spyware? Now it’s necessary to remove this hidden enemy from our systems.

How can I Detect and Respond to Spyware?

How can I Detect and Respond to Spyware

You only need a basic knowledge of some important factors to detect and respond effectively to Spyware attacks and the following is the explanation of prevention, detection, and removal of this malicious virus. 

Spyware Prevention

There are a few preventive measures that you can take to avoid spyware from infecting your operating system. Firstly, as explained above, it’s important to keep your system software up to date with current security updates.

It will reduce the risk of any suspected vulnerabilities that can be victimized by malware. Moreover, download a dependable scanner and external antivirus program and ensure that they are updated with the latest malware implications.

Spyware Detection

Spyware is very tough to detect, as it is made to pass the detection by typical security measures. So, the considerable option to protect your device from the malicious attack of spyware is to recognize the signs that your system is suspected of infection.

These signs can be in the form of a strange activity on your system, such as uninstalled programs appearing on your device that alter your homepage or other important settings. If you see any of these red flags, run a malware scan on your device as soon as possible. 

Spyware Removal

If you suspect that your device has already been affected by spyware, the best way to avoid further transfer of information to criminals is to disconnect your device’s internet. It will restrict the malware from interacting with its Command-and-Control (C2) server. Secondly, scan your entire system using an antivirus program and delete any malware detected. If you don’t know how to do this, you can search online tutorials about your specific antivirus program. Finally, change the passwords that are hacked and contact a professional for assistance. 

Examples of Spyware

An example of spyware can be a program operating in a corporate espionage setting, where malware is present in the computer of an employee overseeing their activity and transferring sensitive information to the cyber-criminal. They may use this information to access confidential data about the corporation like account data or trade secrets.

A well-known example of spyware is Pegasus made by a cyber-arms company NSO Group. High authorities and democratic governments use this program to watch renowned targets like political opponents, journalists, and human rights activists by infecting their iPhones. Consequently, the UN has criticized the NSO Group for threatening the freedom of opinion.

Ransomware

Malware, Adware, Spyware, and Ransomware: What Do These Terms Mean?

Ransomware is a type of malware that puts your personal data at stake and threatens to exterminate it unless it fulfills the ransom’s demand. A ransomware attack makes the computer files inaccessible by encrypting their data. Then the hacker behind this attack sends a ransom note to the victim and asks him to pay the ransom in the form of cryptocurrency if he wants to decrypt and access his files.

Sometimes the cybercriminal destroys the data completely in case the ransom is not paid. Mostly the ransomware is not created by the hacker but a third party provides it to him. This dealing is named as Ransomware-as-a-Service (Raas). In this setting, a malware developer designs the ransomware and sells it to the criminals who use it to threaten their victims. 

In 2021, at least 61% of companies faced ransomware cyberattacks that brought forth a partial disruption. Ultimately, ransomware ended at the end of 2021 by actualizing $20 billion globally, out of which an average business cost is $1.85 million. Moreover, only 57% of these businesses are permitted to recover this data by backup.

How can I Detect and Respond to a Ransomware Attack?

After knowing how much this Ransomware is threatening your finances, it’s important to get some know-how about its detection and removal. So, here is the explanation. 

Ransomware Prevention

As in the cases of other malware types, the best option to prevent ransomware attacks is to keep your device software updated with the latest security updates and install a reliable external antivirus program. 

The other method for minimizing damage that is often neglected by users is running data backups at regular intervals and keeping these backups disconnected from the device either in the form of a cloud storage or an external hard drive. The risk of destruction by a ransomware attack is reduced this way because in the case, the information is lost from the infected computer, you still have your data backup available. 

Ransomware Detection

Just like other malware types, ransomware will hint at itself by slowing down the functions of your computer, installing pop-ups and applications that you don’t know about, and even crashing your computer system. But it’s often too late when a user detects its presence. The user will only see a screen demanding a ransom to unleash the hold of computer files.

Ransomware Removal

Unluckily, there is no proper method to eliminate ransomware and decode files even after fulfilling the ransom demand. However, some malware investigators have made free ransomware removal tools that are operative in certain cases. If you think that your computer has already been attacked by ransomware, you should immediately disconnect it from the internet to stop the malware from penetrating files further. 

Secondly, scan your system with a free ransomware removal tool. If it’s not effective, then you might have to pay the ransom to decrypt your files and get your information back. In the matter of companies, contact their lawyers to get information about the company’s cyber insurance policy before paying the ransom. Moreover, it’s worth considering that some threat actors are sanctioned in the US. So ensure the safety of the transaction before sending any payment. Finally, change the passwords that you believe are hacked and contact a malware expert if you don’t know what to do.
