Do I need an antivirus? It’s natural to ask, but from malware and viruses to phishing scams and identity theft, it’s important to have protection online.
Windows and MacOS have some built-in security features, but these may not be enough. In this article, we’ll explore how antivirus software can protect you and answer the question, “Is antivirus necessary?”

As we share and store increasing amounts of our personal information on the internet, identity theft and ransomware attacks have also been becoming more common. Companies are especially vulnerable to ransomware attacks, which are on the rise globally, but individuals can be targeted, too.
Antivirus apps can help protect you against all of these online hazards. They are widely available, affordable, and easy to use, so it’s wise to invest in your online security.
Antivirus apps offer a range of features that can help protect you from online dangers. In this section, we’ll run through the most important features to look for.
This is an important first line of defense, and it can identify and stop threats before they reach your computer.
Antivirus software can scan your computer for known threats such as viruses and malware. The app will let you know if it finds anything suspicious and let you choose what action to take.
You can generally manually initiate a scan of specific files or folders or choose to scan your whole hard drive. You can also schedule regular automated scans, running every day or every week, so you can have peace of mind that the antivirus is regularly checking for threats without you needing to think about it.
In most cases, scans take place silently in the background and won’t interfere with the performance of your device.
Quarantine is important as it alerts you to threats but also gives you options about how to handle them. If you recognize a file and know the result is a false positive, for example, you can reinstate the file. This prevents accidental loss of important files.
Many antivirus apps offer the option to back up your data. You can choose to back up certain crucial files or make a complete copy of all the apps, data, and settings on your device at a specific point in time. Some antivirus apps let you store backups offline or in the cloud.
Creating a backup allows you to reinstate your device in the event that it’s compromised by malware or if you lose your data due to another unanticipated event, such as a power surge, fire, or theft.
Many antivirus apps include built-in password managers to help address this problem. They work by automatically generating strong, unique passwords for any new online services you want to use and then storing them in a secure vault.
This way, you only need to remember one password to log into the password manager, and you can increase security by adding two-factor authentication, biometric logins, or even physical authentication devices.
Crucially, VPNs can also hide this information from bad actors like hackers and data thieves, which is particularly important if you’re using a public network.
Antivirus apps often include protection against ransomware attacks. This can include data backups, which help you store a copy of valuable information in the cloud or offline to ensure you always have access to it.
More advanced antivirus software can include real-time threat monitoring that uses algorithms to watch out for known ransomware attacks or signature behavior, such as the rapid encryption of files on your device.
The dark web has legal and legitimate uses, but because of its anonymity, it’s also used by bad actors to illegally share valuable data such as user passwords, personal details, and credit card information.
Some antivirus apps offer monitoring services, which can detect if your passwords or personal information are shared online. This can help you to take swift action to protect your data security.
Many PC users wonder if they need dedicated antivirus software for Windows when they already have free access to Windows Defender, also known as Windows Security, in Windows 10 and Windows 11.
The answer is that it depends on how you use the internet and whether the more advanced features available in dedicated antivirus apps are important to you. Windows Defender offers many of the same basic protections against viruses and malware as standalone antivirus apps.
However, it does not include strong protection against phishing scams, it has limited ransomware protection, and it does not include dark web monitoring. In addition, Windows Defender doesn’t offer a password manager or VPN functionality, which can both be useful for protecting your information online.
If you generally follow safe internet practices, such as avoiding suspicious downloads or links, and you have a good system for creating and managing strong passwords, Windows Defender may be enough on its own.
However, if you need additional support with your online safety or if you’re concerned that your device or your personal information may have been compromised in the past, investing in a dedicated antivirus app is a great choice.
Given all the online threats we’ve discussed, you may be wondering – do you need an antivirus app on your phone?
Many antivirus providers offer apps for Android and iOS at no extra cost for subscribers, and it’s a good idea to use a mobile app if you have access to one. However, the more in-depth answer is that it really depends on the type of device you use.
The Apple iOS operating system is already very secure when faced with viruses and malware because of how tightly Apple vets and controls the apps that appear in its App Store.
While viruses are unlikely to be an issue on your iPhone, you may still want to use an antivirus app to block malicious websites, check for data breaches, or use features such as a VPN when you’re using public WiFi.
Android devices are less secure when it comes to malicious software. Malware has appeared in the Google Play Store in the past, though it has always been swiftly removed by Google.
Because you can sideload apps onto Android devices, it’s also possible to bypass the Google Play Store entirely, and this presents another potential vulnerability.
For these reasons, it’s wise to use an antivirus app on your Android device, especially if you can access a mobile app as part of your antivirus subscription.
When you’re weighing up the benefits of using antivirus software, it makes sense to look at the drawbacks, too. There are good reasons why some people choose not to use antivirus apps.
While there are some valid arguments against using antivirus software, the benefits outweigh the negatives. Antivirus app subscriptions are generally very affordable, and performance impact is unlikely to be a problem if you’re using modern hardware.
Most importantly, antivirus apps offer significantly enhanced protection against threats compared to built-in security tools across a wide range of devices. So, is virus protection necessary? We’d say it is.

Do you need antivirus software with a VPN? Antivirus programs and VPNs work together to protect your device and your online activity, but they serve different purposes. To maximize your online safety, it’s best to use both an antivirus program and a VPN.
Antivirus software scans your device for threats such as malware. If it finds a suspicious file, it can quarantine or remove it and prevent it from affecting other files on your device.
These apps can also monitor your internet traffic to alert you to potential threats before they make it onto your device.
VPNs, on the other hand, help to obscure your internet usage and personal information from bad actors like data thieves by anonymising your online activity and device information.
It’s especially important to use a VPN when you’re accessing the internet from a public or unsecured network, such as the WiFi in a coffee shop or airport lounge.
Both antivirus apps and VPNs are important tools to increase your safety online and protect your personal information, and you should use both wherever possible.
Once you’ve decided on the antivirus software you want to use, you’ll want to optimize its performance to make sure it runs well and doesn’t interfere with other tasks on your device. Here are some simple steps you can take to keep your antivirus at peak performance.
Check out our in-depth antivirus guides for more information and to help you decide on the best antivirus app for your needs.
Online threats emerge every day, from viruses and malware to phishing scams and ransomware attacks. Antivirus software provides a crucial defense against these dangers, helping to keep your online activity safe and your personal information protected.
Given this, the answer to the question, “Is antivirus software needed?” is a resounding yes. There are a range of excellent free and paid antivirus apps on the market that offer high levels of performance and protection.
Key features to look out for include firewalls, VPNs, cloud and local backups, password management, and dark web monitoring.
Many paid options can be used across all your devices, including smartphones and tablets, and can also offer protection for multiple members of your household.
Even if you have safe habits online and your device includes built-in security protections, it’s still a good idea to use dedicated antivirus software for the extra protection it provides.
Yes, it’s always a good idea to use antivirus software, even if your device has built-in security features. Antivirus software is affordable and offers a higher level of protection online. Antivirus apps also often offer other features to improve your online security, such as enhanced firewalls, quarantines, VPNs, backups, and password management.
McAfee is one of many antivirus options on the market today for Windows 10 users. It may be the right option for you, but we recommend comparing its price, features, and performance against other antivirus products so you can make the best choice for your needs.
Yes, it’s a good idea to use antivirus software on your phone, especially since many antivirus providers offer iOS and Android apps at no extra cost with their subscription plans. Mobile devices tend to be more secure against malware than computers, but there are still many online threats that can impact your mobile device.
Windows users benefit from built-in security protection with Windows Defender, also known as Windows Security. This may offer sufficient protection for your needs. However, dedicated antivirus products offer a higher level of protection against malware, and many include extra features that can keep you safer online, such as ransomware protection and dark web monitoring.
The features that come with antivirus programs are designed to protect your personal information and keep you safe online. Phishing protection, VPNs, and file backups are important due to the variety and volume of online threats and scams, which continue to increase every year.
There are some great free antivirus software options available, and it’s a good idea to use one of these if you don’t want to choose a paid service. Antivirus apps charging a fee are generally more reliable and have more features. If you need protection for multiple devices, a paid plan is a great choice.
