Do You Really Need Antivirus Protection


In general, antivirus software is still generally necessary, but particular gadgets may require it more than others.

iPhones are the only devices that do not require the installation of antivirus software. Android, macOS, and Windows devices still require antivirus software.


New viruses malicious software and other internet hazards appear every day. In actuality, the AV-Test Institute records more than 350,000 new malware samples and potentially unwanted programs (PUA) daily.

is antivirus software needed?

Yes, you read that correctly: daily. Malware cyber threats will make up approximately 90% of all threats in 2020 compared to PUAs’ 12% share, making it a bigger issue overall than PUAs.

However, some operating systems-most notably Windows-are far more vulnerable to infections than others. According to managed service providers, as of January 25, 2021, 87 percent of ransomware targeted Windows computers (MSPs).

According to AV-Test data, Windows devices had the freshest malware and PUA throughout the entire year of 2020 and the first month of 2021, followed by Android devices and Macs. In conclusion, antivirus software windows security is essential unless you own an iOS device such as an iPhone or iPad.

Do You Still Need Antivirus Protection?

Yes, you need antivirus protection. Although Mac and Windows devices have built-in virus protection, additional antivirus software is still recommended. Using endpoint protection and response will ensure full safety.


Antivirus software will essentially check your devices for viruses, malware, and other online dangers. If anything, malicious is found, the file will be quarantined and deleted. Let’s delve a little deeper in system preferences.


Main Features

These fundamental components are present in every antivirus program’s software:

  • Behavior-based detection: When malware Microsoft windows and viruses are detected based on their behavior rather than their presence in existing databases, the program is able to detect them.
  • Scanners: The majority of software malware attack offers scheduled, always-on, and on-demand scans that you can use as needed.
  • Quarantine and removal of viruses: If the software finds a virus, it will quarantine it so that it cannot spread to other parts of your device endpoint security and then totally delete it.
  • Protection security software for web browsing: Antivirus software guards you both locally on your device windows pc and online against everything from phishing emails to harmful websites.

Special Features

Many antivirus programs come with other digital security programs, like:

  • Parental controls: Parental controls set screen time limits and ban access to specific websites to keep children safe online.
  • Firewalls and network protection: While antivirus software on its own is just device-specific, firewalls stop attacks on the network of your device.
  • Secure browsers: The program may come with a secure browser like Tor, which encrypts all web activity three times so that Internet Service Providers cannot monitor your online activities.
  • Password managers: Password managers have a secure vault where they store all of your login information.
  • Cloud storage that is encrypted is the best option for sensitive files.
  • System optimization: Some scrap less.
  • Protection against identity theft: In an effort to stop identity theft, identity theft protection services search across many financial and illegal databases for the user’s personally identifiable information (PII).
  • VPNs encrypt a device’s web activity and IP address to increase privacy and get around the workplace or governmental limitations.


Of course, individuals who disagree with the necessity of antivirus software aren’t entirely mistaken. Neither is it required for iOS devices nor does it even exist for iOS devices.

There is also the argument that antiviral software is costly, which, regrettably, we must concur with. Antivirus typically costs $40 per year, and terms aren’t typically any shorter.


While there are some antivirus programs that are free, these programs typically have restrictions on things like the number of devices you can connect to them or how long you can use them in the app store.

Finally, many people believe that additional third-party software is unneeded because some systems, like Windows and Macs, already come with built-in antivirus protection. We did some research, which leads us to the subject of our next paragraph.


Antivirus software is useless if machines already have virus protection, right? Wrong. Let’s look at some concrete examples.

Microsoft Defender Antivirus

Windows Defender, another name for Microsoft Defender Antivirus, provides continuous defense against viruses, spyware, and other threats across:

  • Apps
  • Cloud storage
  • Email
  • Web

Windows Defender3 is only included with machines running Windows 10 and later, and even then, not all users, particularly corporate users, will be able to use it.

Because Windows Defender lacks endpoint protection and response as well as automated investigation and cleanup, this is the case.

In order to compensate for these shortcomings, Microsoft actually provides a different piece of software called Defender for Endpoint, but users can also choose to use third-party applications.

macOS Big Sur Antivirus

Similar to this, Big Sur-powered Mac threat machines include XProtect, an integrated antiviral program that runs in the background without the user needing to do anything. Apple also provides

  • Gatekeeper: If it detects dangerous activities in the new software antivirus app, Gatekeeper blocks it from operating.
  • Sandbox mode: Apple’s “virtual sandbox,” which is secluded from the rest of the computer, enables Macs to execute software in quarantine.

This built-in protection does not prevent adware or any PUPs (potentially undesirable programs) that have been installed without the user’s knowledge or agreement, despite the fact that these functions are a necessary component of any antivirus software.

That implies that some malware has previously managed to evade detection. Additionally, the “State of Malware” report from Malwarebytes for 2020 revealed a 400% rise in threats against Macs compared to 2019.

So while though using Mac’s built-in antivirus alone is a risk you may accept, redundancy is always a good thing when it comes to digital security, and protection from adware and PUPs is crucial.

Antivirus Software: Free vs. Paid

A lot of free antivirus software is available, whether as subscriptions that are entirely free or as trials, as we previously indicated. But these free options can have restrictions like:

  • Device compatibility: Your operating system may not be compatible with free antivirus software. For instance, only Windows, iOS, and Android devices are compatible with Kaspersky’s free antivirus software.
  • Lack of firewalls: Because Kaspersky, Bitdefender, Avast, AVG, and McAfee are all on our list of the top free antivirus programs but do not have firewalls, you might have to pay for network security.
  • The average user has many devices that need protection against viruses and malware, but many free choices only cover one device.
  • Time: Lastly, while some free options may only be available for a short time, such as 30 days, there are some apps that you can use indefinitely.
  • Free antivirus software is undoubtedly preferable to nothing, but a paid subscription will likely be necessary for complete device security.


Even while certain devices could come with built-in virus protection, running antivirus software from a third party whether it’s free or expensive-is still necessary.

Frequently Asked Questions

Is antivirus really necessary?

Antivirus is still recommended even if you’re using a Mac or Windows device, which both have some amount of built-in virus protection. Installing third-party antivirus software is recommended for complete security, including endpoint protection and response, blocking against malware and possibly undesirable apps, and other features.

Is it OK to not have an antivirus?

It must be one of your layers of security even though it shouldn’t be your sole one (careful surfing is still crucial). Furthermore, there is no valid excuse for Windows not to run an antivirus.

Is antivirus needed?

And if you’re not using Windows Defender at all, do it right away. (Action immediately!) Sadly, antivirus software will still be necessary for 2022. There are a variety of criminals out there who want nothing more than to break into your PC and steal and wreak havoc; it’s not necessary to fight infections anymore.
