The Best Antivirus Software of 2023 (Free and Paid Explained)

To help protect your Windows 11 or Windows 10 computer, Here we have collected the Best paid and Free Antivirus Software to install on your PC

Choosing a good antivirus is never easy, given the large offer on the market for security software against the cyber threats that attack computers used in business and home every day. The choice has become more difficult over time because many competitors have appeared in this sector. To clarify which paid antivirus to choose, we have made a list of the Best antivirus 2022.

How an antivirus works

The first question you are probably asking yourself is How an antivirus works. Without going into too technical details, we can say that this type of software analyzes every file or program that is about to enter the system.

Basically, an antivirus scans that data and blocks it if it matches the “virus signatures”, which is the signature archive where information about malware is entered.

Non-suspicious files or programs are allowed to enter a security first place, present in some antivirus: this is the HIPS (Host Based Intrusion Prevention System). In this space a further scan takes place: reliable data is circulated, while unrecognized data can enter the system, but only in “isolated” environments. At that point it will be the user who decides to open them or not: if he decides not to do so, those files will end up in quarantine, which is the same fate as malware.

The detection engine

In this sense, the detection engine of each antivirus plays a fundamental role. It has a real task as a scanner: it is up to him to protect the computer from potentially dangerous or otherwise suspicious applications. Some antiviruses use the detection engine developed by other manufacturers.

Why Install Antivirus Software?

The answer to this question is simple: because there are vulnerabilities on any electronic device we use, and on any browser, program and site we open every day. For this reason, having an antivirus will be the salvation of your device.
This security software is the last defense that remains before these malicious files actually enter the system. The antivirus will actually detect the intrusion attempt, defending your device.

How to choose the best antivirus?

The criteria for choosing to have the best antivirus are different, and we will see them in more detail in the next lines and guides. When we will analyze the characteristics that cannot be missing because the software of this type can be defined as such.

However, we can tell you that on a general level a quality antivirus must have a good relationship between the protection offered and its size (which should not burden the system too much). Furthermore, an excellent antivirus should not report harmless files: it would be a completely useless activity. Therefore it is good that it is accurate and not approximate in its action.

What features should the best antivirus software have?

Great, now you should have a clearer idea of ​​how a good antivirus works. In the following paragraphs, we go into what are the main features that cannot be missing because the antivirus can be defined as the best with respect to your needs and expectations. The specifications in question are:

  • Malware protection
  • Integration of useful and effective tools
  • Speed ​​and efficiency
  • Easy to use
  • Good quality/price ratio

Perfect, let’s go through each of these points by point.

Malware protection

It is obviously the first aspect to take into consideration: an excellent antivirus must know how to protect your PC from the malware that try to enter it. On the net there are several comparators able to evaluate how much software is able to offer protection: in this way you will surely find the one that you think best suits your expectations.

Integration of useful and effective tools

Another important element is linked to the presence within the antivirus of tools that can prove to be very useful. Among these, there are, for example, periodic scans that can be programmed according to need, but also the perfect integration with e-mail programs, the presence of a live scanner and frequent upgrades.

Speed ​​and efficiency

This is one of the most relevant factors when choosing to buy an antivirus. The latter must be fast and efficient, and above all it must be able to carry out its protective activity without affecting the performance of your device. In summary, the action of the antivirus cannot cause slowdowns at the system level: if this happens, then you will know with certainty that you have relied on a poor-quality antivirus.

Easy to use

Obviously an antivirus, for the delicate task it performs, cannot be difficult to use. This would involve wasting time, and also possible errors. Therefore, it is better to opt for easy and performing solutions.

Good quality/price ratio

Finally, the last aspect that we advise you to evaluate is the value for money. There are several antiviruses on the market that cost a lot and are not that phenomenal.
Continuing reading, you can refer to the products we have selected, certainly the best in terms of efficiency and convenience.

What Kind of Security Software Should You Buy?

Let’s say that those antiviruses that incorporate all the features described above deserve more than a little thought. However, there are two macro-types of security software: antivirus and antimalware. The difference is increasingly blurred, so much so that the terms are often used interchangeably.

In fact, modern antivirus includes all malware protection tools. Antimalware, for their part, try to detect potential cyber threats of various kinds and tend to be more advanced. So it is not the same thing, but anyway we call them all “antivirus” for convenience.

Why use antivirus and not Windows Defender

Before getting into the heart of the guide, we want to dispel one last doubt that someone surely has arisen: why use an antivirus when Windows Defender is already there? This is the security software pre-installed on Windows operating systems, but which by the same admission of the latter turns out to have fairly limited effectiveness.

There are several reasons why we recommend installing other software: Defender is not fast enough to remove threats, fails to block malware in most cases, and Microsoft still does not release enough regular updates to the Defender software.

Do Windows 10 need antivirus?
Yes, Although Windows 10 has built-in antivirus protection in the form of Windows Defender, it still needs additional software, either Defender for Endpoint or a third-party antivirus.

Free or Paid Antivirus


You may also be wondering whether it is better to opt for a free or paid antivirus. There is no universal answer, or rather: it can be said in general that paid software are obviously more complete than free ones, but some of the latter do not demerit at all.

It depends a little on what your needs are, which system you want to protect, and what you expect an antivirus to do. Below we have identified the best paid antiviruses and the best free antiviruses. Here is our selection, let’s go!
