Antivirus software and VPNs are both commonly described as cybersecurity tools, but they protect against different types of risks. Antivirus software primarily protects your device from malicious software such as viruses, ransomware, spyware and other threats, while a VPN encrypts your internet connection and helps protect your online privacy by routing your traffic through a VPN server.
Because they address different parts of online security, using both can make sense for some people. However, a VPN is not a replacement for antivirus software, and antivirus software is not a replacement for a VPN. Whether you need both depends on the devices you use, how you connect to the internet and the type of protection you want.
Antivirus vs. VPN: What’s the Difference?
The simplest way to understand the difference is to look at what each tool is designed to protect.
| Antivirus | VPN | |
|---|---|---|
| Primary purpose | Protect the device | Protect the internet connection |
| Malware protection | ✓ | Usually not the primary function |
| Ransomware protection | ✓ | No |
| Virus detection | ✓ | No |
| Encrypts internet traffic | Generally not its primary function | ✓ |
| Hides your IP address | No | ✓ |
| Helps secure public Wi-Fi | Limited | ✓ |
| Blocks malicious websites | Some products | Some VPNs offer this as an additional feature |
| Protects against phishing | Some products | Some VPNs offer this as an additional feature |
| Protects your device from infected files | ✓ | No |
The exact features depend on the products being compared, but the basic distinction remains: antivirus focuses on threats to your device, while a VPN focuses primarily on your connection and online privacy.
What Does Antivirus Software Protect You From?
Antivirus software is designed to detect, block and remove malicious software from a device.
Depending on the product, antivirus protection can cover threats such as:
- Viruses
- Ransomware
- Spyware
- Trojans
- Worms
- Malicious applications
- Potentially unwanted programs
- Malicious files
Modern antivirus products can also include web protection, phishing protection, scam detection, firewall protection and other security features.
For example, products such as Norton, McAfee, Malwarebytes and Webroot combine antivirus protection with additional online-security features. The exact capabilities depend on the product and plan.
What antivirus doesn’t primarily do
Antivirus software generally isn’t designed to hide your IP address or make your internet connection private. Some security suites now include VPNs, but that is a separate function from their antivirus protection.
What Does a VPN Protect You From?
A VPN creates an encrypted connection between your device and a VPN server. Your internet traffic is routed through that connection, helping protect it from exposure while also replacing your visible IP address with the VPN server’s IP address.
A VPN can therefore be particularly useful when:
- Using public Wi-Fi
- Connecting to networks you don’t fully trust
- You want to reduce exposure of your IP address
- You want additional online privacy
- You want to prevent local network operators from easily viewing your internet traffic
Services such as NordVPN and Surfshark provide VPN protection along with additional privacy and security features.
What a VPN doesn’t primarily do
A VPN doesn’t automatically detect and remove viruses from your computer.
If you download a malicious file while connected to a VPN, the VPN itself generally isn’t a substitute for antivirus software capable of detecting that file.
Some VPN providers offer additional malware or web-threat protection, but that’s different from the VPN encryption itself.
Why Would You Use Both?
The biggest reason to use both is simple:
They address different security risks.
Consider this example.
You connect your laptop to public Wi-Fi at an airport.
A VPN can help encrypt your internet traffic and protect your connection from certain forms of network-level exposure.
Later, you receive an email containing a malicious attachment and accidentally download it.
Your VPN doesn’t replace malware protection. Antivirus software can potentially detect and block the malicious file.
In this situation, the two tools provide different layers of protection.
Does Having a VPN Mean You Don’t Need Antivirus?
No.
A VPN primarily protects the connection between your device and the VPN server. It doesn’t mean that files, applications or websites you interact with are automatically safe.
A VPN also cannot guarantee protection against:
- Malicious downloads
- Infected applications
- Ransomware
- Spyware
- Malware already present on your device
- Social-engineering attacks
Some VPN services now include threat-blocking features that can help identify malicious websites or files. However, those features should not automatically be treated as equivalent to a full antivirus product.
Does Antivirus Make a VPN Unnecessary?
Not necessarily.
Antivirus software can protect your device while leaving your internet connection exposed in ways that a VPN is specifically designed to address.
For example, antivirus software doesn’t normally hide your public IP address simply because it is installed on your computer.
If privacy and connection security are important to you, a VPN can provide an additional layer that antivirus software doesn’t primarily address.
Can One Product Provide Both?
Yes.
This is increasingly common.
Security providers such as Norton and McAfee offer plans that combine antivirus protection with VPN services. Other providers focus specifically on VPN services but offer additional security features.
This can be convenient because you manage fewer subscriptions and applications.
However, “includes a VPN” doesn’t automatically mean “has the same capabilities as every dedicated VPN service.”
If VPN privacy is particularly important to you, compare the VPN’s:
- Encryption and protocols
- Server network
- Privacy policy
- Kill switch
- DNS leak protection
- Device support
- Performance
- Additional privacy features
Likewise, if antivirus protection is your main concern, compare the actual malware and threat-protection capabilities rather than choosing a product simply because it includes a VPN.
Antivirus + VPN vs. Separate Services
There are two common approaches.
Option 1: One security suite
You can choose a product that combines antivirus and VPN features.
Advantages:
- One subscription
- One provider
- Fewer applications to manage
- Convenient for less technical users
Potential drawback:
The VPN or antivirus component may not be the strongest option in its respective category.
Option 2: Separate antivirus and VPN
You can choose antivirus software from one provider and a VPN from another.
For example:
Antivirus: Norton, McAfee, Malwarebytes or Webroot
VPN: NordVPN or Surfshark
Advantages:
- More choice
- You can select the antivirus you prefer
- You can select a dedicated VPN based on your privacy requirements
- Easier to optimize each layer independently
Potential drawback:
You may have two subscriptions and two applications to manage.
Do You Need Both on a Phone?
It depends on how you use your phone.
Modern smartphones already include various built-in security protections, so installing additional antivirus software isn’t necessarily essential for every user.
However, a VPN can still be useful when connecting through public or untrusted Wi-Fi networks or when additional connection privacy is desired.
For Android and iOS users, therefore, the decision should be based on the capabilities already provided by the operating system and the specific features offered by the security products you’re considering.
What About Public Wi-Fi?
This is one situation where a VPN can be particularly useful.
When you connect to public Wi-Fi, you’re using a network that you don’t control. A VPN can encrypt your traffic between your device and the VPN server, providing additional protection against certain types of network-level interception.
However, a VPN doesn’t make an unsafe website safe.
You should still:
- Keep your operating system updated
- Use strong, unique passwords
- Enable multi-factor authentication
- Avoid suspicious links
- Keep security software updated
- Check that websites use HTTPS
A VPN should therefore be considered one security layer, rather than complete protection by itself.
Do You Need Both?
You may want both if:
- You regularly use public Wi-Fi
- You want additional online privacy
- You download files or applications regularly
- You want protection against malware and ransomware
- You use multiple devices
- You want separate protection for both your device and internet connection
You may not need both if:
- You have very basic internet usage
- Your existing security software already includes the features you need
- You rarely use untrusted networks
- You don’t have a particular need for additional VPN privacy
The right decision depends on your actual security and privacy requirements, not simply how many security products you can install.
ProtectionSeek’s Take
Antivirus and VPNs aren’t competing technologies. They solve different problems.
Antivirus primarily helps protect your device and its files from malicious software, while a VPN primarily helps protect your internet connection and online privacy.
For many users, having both can provide useful additional layers of protection. But that doesn’t mean everyone needs two paid subscriptions. A security suite that combines both may be sufficient for one person, while another user may prefer a dedicated antivirus and a dedicated VPN.
The most important thing is to compare what each product actually provides, rather than assuming that a longer feature list automatically means better protection.
