There are a lot of different Antivirus software products on the market, and it can be hard to know which one is right for you. That’s why we have put together a list of the nine best Antivirus Software products available in 2023, to help you make an informed decision.

We’ll tell you what each product offers, and what sets it apart from other Antivirus software. So whether you’re looking for comprehensive protection or something more specific, you’ll be able to find the right fit for your needs.

Before we list the 9 best antivirus products we felt it useful to answer some common questions and to dispel some myths.

What is Antivirus software and why is it important

Antivirus software is designed to protect your computer from malicious threats like viruses, worms, and Trojan horses. It scans files and emails for malicious code and blocks them before they can do any harm. It also helps prevent unauthorised access to your personal and sensitive data.

There are many different types of antivirus software application available on the market. Some provide basic protection from viruses, while others offer more comprehensive protection against a wider range of threats.

It’s important to choose an antivirus software application that meets your needs and offers the best possible protection for your system within your price range.

Are there different types of Antivirus products on the market?

Yes, there are different types of Antivirus software products on the market in 2023. Some antivirus products provide basic protection from viruses, while others offer more comprehensive protection against a wider range of threats.

There are two primary types of Antivirus software on the market in 2023: signature-based and behaviour-based solutions, each with its advantages and disadvantages.

It’s important to choose an antivirus software application that meets your needs and offers the best possible protection for you, your family and your business.

What are signature-based antivirus software solutions?

Signature-based antivirus solutions are one of the oldest and most widely used forms of computer protection software.

Signature based Antivirus software works by comparing specific patterns, or “signatures” against any malicious code it finds. If a match is found, the malware is blocked before it can do any damage to your computer.

The virus signatures are regularly updated to keep up with the latest threats, allowing the host Antivirus software to effectively detect and remove malicious code from your device.

Cyber Security - Jon Cosson CISO

Signature-based antivirus software is highly effective at blocking known threats, but it is not as good at protecting against unknown or zero-day threats.

This means that new types of malware may still be able to slip through its defences and infect your computer system. For this reason, it is considered important to use other security measures in conjunction with signature-based antivirus solutions.

Signature-based Antivirus software also require more computing power than other forms of virus protection, as they must compare each piece of data against all the signatures in their database. This can slow down certain operations on your device, such as file copying and downloading large files.

To mitigate this issue, some products offer real-time functions that only scan newly downloaded files or specific areas of memory for threats.

Overall, signature-based antivirus software offers a reliable form of protection that provides comprehensive coverage against known threats and can be used in conjunction with other security measures for maximum effectiveness.

What is behaviour-based Antivirus software?

Behaviour-based Antivirus software solutions are a relatively new form of next generation computer protection software. Instead of relying on signature-based detection to identify malicious code, these solutions use behavioural analysis and machine learning algorithms to detect suspicious activities

Behaviour-based solutions continuously monitor processes running on your computer, looking for any abnormalities or patterns of activity that may indicate malicious intent. If any suspicious activity is detected, it can be blocked before it can harm your system.

Cyber Security - Jon Cosson CISO

Unlike signature-based antivirus software, behaviour-based solutions don’t require frequent updates as they can identify new threats in real time by analysing their behaviour patterns rather than relying on pre-existing virus signatures.

This makes them more effective at detecting unknown or zero-day threats – which signature-based systems often struggle to detect.

However, this also means that behaviour-based Antivirus software can generate false positives (false alarms) if the behaviour being monitored matches that of an actual malicious application but turns out to be something harmless instead.

To help mitigate this issue, behaviour-based antivirus software usually deploys Machine Learning algorithms to adapt the criteria used to determine which behaviours are considered malicious over time.

Overall, behaviour-based antivirus software provides an effective way to protect your device against a wide range of malicious code and online threats in real-time. They are particularly useful for businesses and organizations that need high levels of security and need their Antivirus software to stay up-to-date with the latest threats without requiring frequent manual updates or maintenance.

Do you require Antivirus software for a Mac computer?

The short answer is Yes, it is highly recommended to have antivirus software installed on your Mac computer. It is somewhat of an urban myth that Mac computers do not require Antivirus software.

Macs are not immune to malware infections, they are just as exposed to viruses and malware as Windows-based computers, so it is important to equip them with a good antivirus software solution to keep them secure.
