What is Antivirus Software?

Anti-virus software is one of the most important weapons in your arsenal to protect your device. As attacks on your device become more sophisticated, it’s important to understand exactly how antivirus software works.

What is an anti-virus?

Anti-virus software scans, detects and removes viruses and other malware such as worms, Trojan horses, adware and more. The software is designed to act as a proactive method of network security, stopping threats before they enter your computer and cause problems.

While you may think your computer is safe as long as you don’t visit frivolous websites, hackers have more subtle ways of planting their viruses on your computer, which is why you need a strong antivirus to stay one step ahead of them.

How does antivirus software detect and remove viruses and malware?

Different types of Internet threats caused by different online activities – emails, clicking on links, web browsing, downloading or transferring files or applications, and video camera recordings and calls – require different antivirus solutions. These include, among others, the following.

Signature analysis: Signature-based analysis is similar to fingerprint analysis and is one of the most common types of anti-virus threat detection. All anti-virus software vendors compile and continuously update a database of threats detected from suspicious files and websites, known as ‘virus definitions’.

Anti-virus software compares the fingerprints or ‘signatures’ of identified potential threats with the threats analysed in this database and reacts accordingly when a match is found.

Times have changed significantly since the early days of basic worms and self-replicating computer viruses. While malware has evolved and remains a threat, there are many other ways for cybercriminals to attack.
