What is antivirus software – definition, types & functions
Cybercrime remains rampant, with malicious strangers going to great lengths to take control of users’ devices, such as setting up phishing websites or files to lure them into downloading. However, thanks to the rapid advancement of technology, many countermeasures have emerged. You can use antivirus software or a VPN to prevent virus intrusions. For instance, you can download LightningX VPN to encrypt your data and IP.
Next, we will provide a detailed explanation of “What is antivirus software.”
What is antivirus software?
Antivirus software is a program designed to protect electronic devices and networks from viruses. It acts as a safeguard, preventing, detecting, and eliminating any potential risks or suspicious malicious activities on the host device.
Antivirus software is not inherently equipped to defend against all viruses; its development relies on the ongoing evolution of new threats. As seen today, there is a wide range of viruses, including Network Virus, worms, Trojan Horse, Spyware, rootkits, adware, and more.
To address various threats, tech companies must research the characteristics of viruses and continuously improve their products.
What does antivirus software do?
Standard antivirus software has a comprehensive feature package for users to keep their devices safe at any time. Here are the general functions.
- Scans specific files or directories for any viruses or malicious activities.
- Allows users to schedule automatic scans.
- Enables users to scan any file or flash drive at any time.
- Removes any malicious code detected or prompts users to delete the infection files.
- Prompts users to initiate the computer.
A security assistant of antivirus software
Unlike antivirus software, the VPN is prone to circumvent all the risks from the source. When you do online activities, your data should be exposed to ill-intentioned strangers like hackers. A VPN creates an encryption tunnel using the VPN protocols and lets your data and traffic pass through this tunnel.
LightningX VPN is one of the strongest VPNs. It adopts the best VPN protocol WireGuard, based on military-level algorithms like AES-256-GCM and ChaCha20-Poly1305. Meanwhile, it sticks to a strict no-logs policy.
It unblocks popular platforms like Netflix, YouTube, Disney+, Steam, Epic Games, Instagram, and Twitter from anywhere in the world. You can change your IP address to 2,000+ regions from 50+ countries including South Korea, Japan, Russia, Brazil, and Mexico. Each node has unlimited traffic and connection speed. Also, its Smart Mode allocates traffic to specific websites so you can access the desired website faster.
LightningX VPN is compatible with Windows, macOS, Android, iOS, Apple TV, Android TV, and Linux. It allows 3 simultaneous devices in the basic plan and supports a customizable service.
It has affordable plans and a free trial for beginners.

Types and adoption of antivirus programs
Antivirus software includes standalone antivirus scanners, machine learning and cloud-based programs, malware signatures, and Internet security software suites. They can be adopted on different operating systems for virus protection.
On Windows: Windows Defender is commonly used for protecting Windows systems. It was first offered by Microsoft in 2004 for free. It has two versions; one is Microsoft Defender Antivirus for individuals, and another is Microsoft 365 Defender portal for businesses. Users can also choose to use a product designed by a third vendor.
On macOS: Apple’s products use an enclosed operating system including macOS and iOS. On macOS, the chance of getting infected by viruses is much lower than on Windows. So, antivirus programs are not that necessary for macOS devices, and they develop slowly. However, there are still several products for protecting Mac-based devices against potential risks.
On Android: Android is easier to attack than other mobile Oses because it is open and the most used. The manufacturers generally integrated free antivirus software on Android devices. It meets the basic need for scanning, detecting, and preventing malicious files, apps, or websites. There are also many options for users, but most require a fee.
Anti-malware vs. antivirus
Both antivirus and anti-malware protect you against malicious patterns. However, they have some subtle differences.
Antivirus and anti-malware can both defend against common viruses and various types of malware. However, anti-malware has more advanced protection resorts, such as preventing hidden keyloggers that steal your keystrokes or rootkits that help hackers control your device.
Generally, antivirus software is designed to combat traditional viruses, while anti-malware offers stronger real-time monitoring and behavior analysis capabilities, making it more effective against emerging and advanced threats.
In the end
Antivirus software is an essential part of our online lives, with many manufacturers pre-installing it on our devices by default. However, it’s important to remain vigilant about any potential threats and avoid them. Now, activate your antivirus software and let it perform a thorough scan of your devices.
