In today's digital age, we rely heavily on our computers and devices to work, communicate, and connect with others. However, with the vast amount of information that we share online, the risk of cyber attacks and malware infections is higher than ever before. This is where antivirus software comes in - it is a critical tool that can help protect your devices from viruses, malware, and other online threats. Antivirus software works by scanning your computer for potential threats and either removing them or quarantining them so that they can't cause harm. In this blog post, we'll take a closer look at what antivirus software is, how it works, and why it's so important to have it installed on your devices. So, let's get started and learn more about this essential cybersecurity tool.

What is Antivirus?
Antivirus software, commonly known as anti-malware software, is a program that protects your computer or mobile device against dangerous software such as viruses, spyware, adware, and other forms of malware. Antivirus software often detects possible threats by scanning your device and comparing the results to a database of known malware signatures. If the software identifies any unusual behaviour or code, the dangerous files may be quarantined or removed to avoid further damage to your system. Antivirus software is an essential tool for safeguarding your personal data and combating cyber assaults.
Which is the first Antivirus and when it was created?
Bernd Fix and Paul Gbel, two computer scientists, developed the first antivirus software in 1987. The "Vienna Virus" software was created to detect and remove a specific sort of malware known as the "Vienna" virus, which was spreading quickly at the time. The Vienna Virus was one of the first computer viruses to infect both IBM-compatible PCs and Apple Macintosh machines via the boot sector of floppy disks. The Vienna Virus was not particularly harmful, but it was extremely contagious, prompting the development of the first antivirus software as a countermeasure. Antivirus software has now become a crucial tool for safeguarding computer systems against many sorts of malware, such as viruses, worms, Trojan horses, and other types.
How Does the Antivirus Program Works?
Antivirus software detects and removes dangerous software from your computer or mobile device using a variety of approaches. Here's a quick rundown of how most antivirus products work:
1. Signature Detection:
This technique employs a database of known virus signatures. When the antivirus software scans your device, it compares the files on your device to its signature database to see if there are any matches. If there is a match, the antivirus software quarantines or deletes the file.
2. Behavioural Detection:
This method examines the behaviour of software on your device to see if it is performing maliciously. Antivirus software may detect patterns of behaviour such as attempting to edit system files, generating new files in questionable locations, or attempting to modify system files.
Heuristic detection entails recognizing potentially suspicious code that has not yet been identified as a known malware signature. Antivirus software may detect code that resembles known malware signatures and mark it as potentially hazardous.
3. Sandboxing:
It is isolating a suspicious file and executes it in a safe environment to evaluate if it exhibits any dangerous behaviour. This method is frequently used for files that are tough to evaluate with other methods.
4. Real-Time Protection:
Several modern antivirus products offer real-time protection features that constantly monitor your device for malware and prevent it from causing harm.
Antivirus software can help defend your device from a wide range of malware threats by combining these strategies.
How to use Antivirus?
1. Install Antivirus Software:
First, you need to download and install antivirus software on your computer or mobile device. You can purchase antivirus software from various vendors or use a free antivirus program that provides basic protection.
2. Update Antivirus Software:
After installation, it is essential to update your antivirus software regularly to ensure that it has the latest malware signatures and software updates to detect and remove new threats.
3. Perform a System Scan:
Once your antivirus software is up-to-date, perform a full system scan to detect any potential malware threats on your device. Some antivirus software may also include a quick scan option that scans commonly infected areas of your device.
4. Review Scan Results:
After the scan is complete, review the results to see if any malware was detected. If malware is found, follow the recommended actions suggested by the antivirus software to remove or quarantine the files.
5. Schedule Regular Scans:
To keep your device protected, schedule regular scans of your device using your antivirus software. This will help ensure that any new malware threats are detected and removed promptly.
6. Be Proactive:
In addition to using antivirus software, it's essential to practice safe browsing habits, such as avoiding suspicious websites and emails and keeping your device software up-to-date.
Do we need Antivirus on our devices?

| Do we need Antivirus on our Devices? |
Yes, it is highly recommended to have antivirus software installed on your devices, especially on computers, as they are more vulnerable to malware attacks than mobile devices. Antivirus software provides a critical layer of protection against various types of malware such as viruses, spyware, ransomware, and other malicious software that can harm your device and compromise your personal information.
Malware attacks can occur in several ways, such as opening infected email attachments, downloading software from untrusted sources, visiting compromised websites, or connecting to an infected network. Antivirus software can detect and remove such malware threats and provide real-time protection against new and emerging threats.
Moreover, with the increasing use of online services, cloud computing, and social media, cyber threats have become more sophisticated and prevalent. Without antivirus software, your device may become vulnerable to malware, which can result in data loss, identity theft, financial fraud, and other cybercrimes.
Therefore, it is highly recommended to install and use antivirus software on your devices to protect them against malware threats and keep your personal information secure. Additionally, it's essential to keep your antivirus software up-to-date to ensure that it can detect and remove the latest malware threats.
In conclusion, antivirus software is an important tool for protecting your devices from many forms of malware attacks. It protects your device from dangerous software like viruses, spyware, and ransomware, which can destroy your device and compromise your personal information. With the sophistication and prevalence of cyber threats increasing, it is critical to install and utilize antivirus software on your devices, as well as keep it up to date, to guarantee that it can detect and remove the most recent malware threats. You can protect your devices and personal information from cyber-attacks and stay secure online by taking proactive measures such as running antivirus software and practising safe browsing practices.
