What is an antivirus?

An antivirus, also known as anti-malware, is a software that pretends to detect, prevent, and remove malware (malicious software) from a computer. Malware includes viruses, Trojan horses, worms, spyware, adware, ransomware, and other harmful software that can steal personal information, damage files and software, or even control a computer remotely.

In order to maximize the effectiveness of an antivirus program, it is important to keep the software up-to-date with the latest malware definitions. Additionally, it’s essential to keep the operating system and other software up-to-date. In this way, we prevent a vulnerability from affecting the security of the system.

It’s also important to note that no antivirus software can provide 100% protection against all malware. Moreover, it’s still possible to get infected even with a good antivirus program. However, using an antivirus program can greatly reduce the risk of infection and can quickly detect and remove malware if it is present on a computer.

What methods does an antivirus use to neutralize threats?

Antivirus software typically works by using a combination of techniques to identify and remove malware. Let’s take a look at them.

1. Signature-based detection: This is the most traditional method of antivirus protection. It involves maintaining a database of known malware signatures that the software can scan for on a computer. When a match is found, the software will alert the user and take action to remove it.
2. Heuristic-based detection: This method involves analyzing the behavior of a program to determine if it is malicious. For example, if a program attempts to access sensitive system files or make changes to the registry, it will appear as malware.
3. Sandboxing: This is a technique where the antivirus runs a program in a virtual environment (sandbox) to observe its behavior before deciding if it’s malicious or not. This way, even if the program is unknown, the antivirus can still detect and prevent it from doing any harm.
4. Real-time protection: This feature allows the antivirus to constantly monitor the computer for suspicious activity and take action immediately when malware acts.
5. Cloud-based protection: This method uses the power of cloud computing to analyze malware samples in real-time. This allows antivirus software to quickly detect and protect against new and emerging threats.

Main security threats affecting Windows computers.

There are several major security threats that can affect Windows systems, including:

• Viruses: A virus is a type of malware that attaches itself to a legitimate program, such as a document or an executable file, and then replicates itself when the program is run. Viruses can cause a wide range of problems. For example, slowing down a computer or stealing personal information.
• Trojan horses: A Trojan horse is a type of malware that disguises itself as a legitimate program. However, it actually contains malicious code that can harm the computer or steal personal information. Moreover, Trojans can to create a back door into a computer, allowing an attacker to take control of the system or use it to launch attacks on other computers.
• Ransomware: Ransomware is a type of malware that encrypts the victim’s files and then demands a ransom payment in order to decrypt them. Ransomware can be very difficult to remove, and may cause significant data loss.
• Worms: A worm is a type of malware that is able to replicate itself and spread through a network or the internet without the need for a host program. Worms can cause a wide range of problems. For example, slowing down a computer and causing a Denial of Service (DoS) attack on a network.
• Adware and spyware: Adware and spyware are types of malware whose function is to display unwanted advertisements or collect personal information. Adware often sneaks in with free software. On the other hand, spyware can be installed through phishing emails or infected websites.
• Rootkits: A rootkit is a type of malware whose design wants to hide itself from detection. Rootkits can be very difficult to remove, as they regularly run at a low level and can change the way the operating system works.

What habits should we maintain to increase the security of our operating system.

There are several habits that you can maintain to increase the security of your operating system, including:

• Keep your software up to date: Software vulnerabilities are often discovered and patched by software vendors. By keeping your operating system and all of your installed programs up to date, you can reduce the risk of these types of attack.
• Use a firewall: A firewall is a security tool that controls incoming and outgoing network traffic. By using a firewall, you can block unauthorized access to your computer and protect it from network-based attacks.
• Practice safe browsing habits: Be cautious when visiting unfamiliar websites. Besides, avoid clicking on links or downloading files from untrusted sources. Use a browser extension like uBlockOrigin to block unwanted ads and pop-ups.
• Use a password manager: Using a password manager can help you create strong, unique passwords for each of your accounts. In consequence, make it much more difficult for someone to guess or crack your password.
• Use a VPN: A VPN (Virtual Private Network) encrypts your internet connection and helps to protect your online activities from prying eyes. This can be especially useful when you are using a public Wi-Fi network.
• Back up your data regularly: Regularly backing up your data can help you recover from a security incident or a hardware failure. This can include using an external hard drive, cloud storage, or a remote backup service.

In this way, we learned what an antivirus is and how it works. See you later!

List of the best antivirus

Here is a list of the best cybersecurity programs that you can install on your computer. Which antivirus programs are the best? Here are our suggestions:

• Bitdefender
• McAfee
• G-DATA
• Malwarebytes
• Norton
• F-Secure
• Avira Antivirus
• Sophos Home
• Kaspersky Antivirus
• Windows Defender

BitDefender

We begin this list with Bitdefender. This is an option with excellent results in independent lab tests. In addition, it includes very interesting additional features. With this cybersecurity suite, you protect yourself from ransomware and prevent tracking. You also get banking protection and enjoy a password manager.

But, despite the many functions that come with it, some of them are limited. Indeed, the VPN requires a separate subscription. This is also true for something as basic as the key manager. On the other hand, Bitdefender is perfect for those who don’t want to worry about configuring the antivirus. In fact, its autopilot launches the appropriate protections as needed.

McAfee

McAfee is a very complete cybersecurity suite. In fact, it has applications for all types of operating systems. Therefore, you can use it on Windows, macOS, ChromeOS, Android or iOS. Tests carried out by specialized agencies leave it in very good place.

Although it is an excellent option, it also has some weaknesses. For example, the analysis on Windows is very slow. In addition, it has a somewhat poor Mac version. Additionally, it is not always effective in protecting the user against ransomware.

G-DATA

G-DATA is an antivirus of German origin that was first launched in 1985. For this reason, there is no doubt that this company has experience in security. In rankings such as the AV Test, it gets the best possible score. On the other hand, it comes with very interesting features, such as detection of banking Trojans, keyloggers, ransomware, and exploits. It even has a spam filter.

Malwarebytes

Malwarebytes stands out for its high protection rate. It claims to be one of the strongest shields against malware. However, its platform goes far beyond that. It includes full fast scanning, protection against exploits, ransomware and behavior-based detection. So what’s wrong with that?

The truth is that some laboratory tests confirm it as one of the best antivirus that you can install. Curiously, other organizations give it a worse score. These disparate results may make you doubt its real effectiveness. However, when you wonder which antivirus programs are the best, Malwarebytes is part of the answer to that question.

Norton

Clearly, Norton is one of the best known antivirus products. Tests carried out by specialists make it clear that it is one of the most effective protections you can have on your PC. In addition, it includes several interesting features, such as a password manager, firewall or online backups.

Norton’s worst flaw is its high price. Additionally, it does not offer discounts on the purchase of large volumes of licenses. If you were looking for a protection system for your company, you may find it more profitable to choose other options.

F-Secure 

F-Secure has an excellent score in antivirus protection tests. Likewise, its database is constantly updated. Therefore, it detects new malware appearing on the network. Its interface is simple and effective, in addition to having a low price. On the other hand, it is not always effective against ransomware attacks. Nor does it include protection against other kinds of threats, such as phishing.

Avira Antivirus

Avira Antivirus is one of the best free options included in this guide. Apparently, its developers have found the balance between a high threat neutralization rate, we are talking about up to 99.7% according to AV Test, and a low impact on performance.

Avira’s interface is frankly attractive. It is simple and includes several settings to customize the antivirus. It also includes interesting options, such as a free VPN and anti-ransomware protection.

Sophos Home

Sophos Home gives you protection against external attacks on 10 devices. Obviously, this includes your Mac and Windows computers. This is a recommended option, since its antivirus platform is very powerful. The main problem with this alternative lies in its somewhat clumsy interface and lack of advanced settings.

Despite this, it is a good option that relies on artificial intelligence to detect security flaws and attacks. On the other hand, if you are concerned about the integrity of your files, you should know that it has advanced protection against ransomware.

Kaspersky Antivirus

Kaspersky has very good protection against viruses and other malicious programs. In addition, it is available on Windows, but also on Mac, Android, and iOS. Among its advantages, you will find the wide variety of options available to configure the protection against viruses. It is also prepared for other kinds of threats, such as ransomware.

The trade-offs are clear: the extras included, such as security wizards or a VPN, are very limited. Sadly, the latter feature does not offer connections from other geographical locations and has a limit of 200 MB per day. Therefore, Kaspersky is not for you if you are looking for the best VPN for your computer, as well as protection against threats.

Windows Defender

We close the list with an antivirus that all Windows users already have. This is Windows Defender, included natively by Microsoft in its operating system. In addition to having many options, the evaluations that independent organizations make of its protection against threats are very positive.

Undoubtedly, one of its strong points is its integration with the operating system. In fact, after installing Windows, the user does not have to do anything to be protected by this software. Evidently, it is a free antivirus that you will be able to configure from the Windows Security section.

On the other hand, the interface has been improved over the years to make it much more modern and accessible to any user. Regardless of their computer skills.

Avast

Avast antivirus has undergone many changes recently. We hope it has learned from its mistakes. This has meant that it has finally established itself as one of the best options according to the tests practiced. Especially when it comes to counteracting any type of threat that enters the device. And this is completely logical, since it is still one of the most popular and sought after.

So, it has a high security rating for countering Zero Days attacks and general malware. But it is also committed to good performance and usability. In addition, it integrates a VPN in the payment options to maintain your privacy on the network.

In addition, a parental control that any parent can activate to have a control of the Internet activity.

AVG

AVG promises to offer simple and complete protection for up to 10 devices in its top plan. In tests, it obtains 100% effectiveness for attacks against the vast majority of Zero Days attacks. In addition, it protects against the most common malware found on the network. Additionally, it does not interfere with navigation as it does not offer any false positives during the tests performed.

The problem that can be found with other options on the market are the performance. That is to say, it is one of the top antivirus that most impairs performance. Especially, this is something that can be seen present in standard computers that do not have a mighty hardware. But this is the only negative point. Indeed, it also happens that it does not interfere with false positives while you are surfing the Internet.

F-Secure

F-Secure is certainly not a well-known antivirus among users. However, it is also at the top of the rankings. It promises protection against a virus or malware. But it also includes the possibility of secure online banking and shopping. This is achieved by integrating into browsers. It also blocks all websites that do not have the necessary protection or are registered as risky sites for scams.

In addition, it adds a VPN connection to guarantee your privacy while you are surfing the Internet. Protection blocks practically 100% of the threats on the network. But also in performance and usability, it achieves the highest possible score in the tests. Especially because it does not slow down the computer or interfere with the user experience.

G-Data

G-Data has the latest anti-ransomware technology. Therefore, no attacker will be able to access your data and demand a ransom in exchange for it.

Once installed, it will start scanning the system for threats. The wizard offers 3 types of scanning: quick, full, and customized.

Once the mode is selected, the system scan will start. Depending on the type chosen, it may take a long time.

After a while, you will see the final result of the analysis.

Microsoft updates MSRT once a month. Specifically, on the second Tuesday of each month with the Windows security patch. The update integrates the main threats that have been detected during the previous month. In addition to instructions on how to remove the malicious software from the computer. This is its best feature. Since it is constantly updated, it improves its ability to respond to threats. Consequently, the computer will be more protected. However, it is not a definitive solution.

There are various ways to prevent malware from doing so and there are also ways to ensure that even after a successful malware attack, you don’t lose your mission critical data. Preventive measures include the acquisition of anti-malware software whereas the cure for a malware attack are data recovery services such as backup and disaster recovery services (On-premises & cloud based).

In order to help you protect your data from malware attacks without any cost implications, here’s our list of the best free anti-malware software:

1.  AVG Antivirus Free

AVG Antivirus comes with a simple interface and facilitates remote activation of system scanning. It’s at the top of our list not just because of the simple yet effective and easy to manage dashboard. The anti-malware application also protects from downloadable threats and dodgy links.

Remember those phishing emails? You’re sent a link for something else but instead it leads to a ransomware/malware infection? That’s what AVG protects you and your data from. And that’s the main reason why it’s at the top. Apart from remote scanning activation, of course.

It comes with a free version but also offers a Pro version, for which you have to pay some amount but then you gain access to enterprise level security features.

2. BitDefender Antivirus Free Edition

This antimalware application is the silent vigilante working in the shadows. It is discreet yet effective. The application identifies and eliminates anything that poses a threat to your system/PC.

BitDefender scans links to ensure you don’t fall victim to malware, identifies misbehaving applications, and scans your PC every time you start it up.

3. MalwareBytes Anti-Malware

The reason why this anti-malware is ranked third is not because it’s bad or isn’t satisfactory. It’s because the free version doesn’t support real-time protection, hyper-scan mode and malicious website blocking feature. After the free trial expires, you lose access to a number of great features.

Apart from that, the application efficiently protects your PC from malware and has a reputation for it. As the free version supports the standard link scanning and malware detection features; you can use it without worry. However, for advanced features you will have to purchase the software. Think of the free version as a test-drive for the real deal if you are looking for enterprise level security features.
