Did your friend group tell you that iPhones don’t need antivirus protection? Well, they’re half right. iOS is incredibly secure compared to other platforms. However, today’s threats have evolved way beyond traditional viruses. Users face phishing attacks, data breaches, identity theft attempts, and malicious websites that Apple’s built-in security simply wasn’t designed to handle.
Antivirus apps for iPhone can counter attacks by monitoring web browsing, checking if passwords have been leaked, and helping you avoid clicking anything in sketchy text messages. After testing dozens of apps, these are three we recommend downloading from the App Store.

Methodology: How We Test iPhone Antivirus Apps
We test apps against the same real-world scenarios that iPhone users face daily. Our team of cybersecurity experts evaluates each app across five key categories:
- Malicious website blocking: We tested each app’s ability to block malicious websites by visiting 24 known phishing sites and calculating their detection rates.
- Wi-Fi security scanning: We ran scans on our saved public Wi-Fi hotspots to see how secure they were.
- Identity monitoring capabilities: We assessed the additional tools that protected our identity while searching for potential gaps in our security profile.
- System performance impact: We have enough apps that drain our iPhone battery, so we ran tests to see the strain antivirus apps were putting on our device.
- Ease of use: Not everyone is a security expert, which means we have to assess everything from the installation process to the app navigation.
Each app undergoes a minimum 30-day testing period where we use it as our primary security solution on multiple devices. We also factored in independent lab results from AV-TEST and AV-Comparatives when available, though fewer iOS apps undergo formal certification compared to their desktop counterparts.

1. Norton Antivirus - Best Phishing Protection
View Plans Links To Norton
Product Specs
Virus Detection Yes Malware Detection Yes Firewall Yes Full, quick, and scheduled scans Yes Real-time protection Yes Behavior-based monitoring Yes
During our Norton Antivirus testing, the mobile app consistently blocked every phishing link we tried opening, including sophisticated ones that mimicked banking apps and Apple’s own login pages. The identity monitoring feature even caught a data breach involving our email address within 48 hours of it happening.
This level of protection is why Norton Antivirus is in the top spot. Our test results gave us complete peace of mind that it would be incredibly difficult for any threats to break through its defenses.
FYI: Online threats can be costly. FBI’s Internet Crime Complaint Center report found that financial losses from cybercrime in 2024 reached $12.5 billion.1
What We Like
- Blocks even the most sophisticated phishing attempts
- Identity monitoring quickly flags data breaches
- The security report is clear and easy to understand
What We Don’t Like
- Premium features are expensive
- VPN is reliable but lacks advanced options like split tunneling
- Some features feel redundant if you already practice safe online habits
Getting Started With Norton Mobile Security
Setting up Norton took us about five minutes from download to full protection. The app walked us through enabling web protection in Safari, setting up Wi-Fi security alerts and configuring identity monitoring. What impressed us most was how Norton automatically imported our saved Wi-Fi networks and immediately flagged two public networks we’d previously connected to as potentially unsafe.
We also like that every feature includes a brief explanation of what it does and why you might need it. During setup, Norton found that three of our passwords had been exposed in data breaches.
We like that Norton is easy to navigate and tells us when Wi-Fi networks are safe to use.
Norton Web Protection
Norton’s web protection is where this app truly shines. It blocked 99.9 percent of malicious websites and flagged fake suspicious emails and links we sent to ourselves. As we dug deeper, we learned that the Genie Scam Protection feature uses machine learning to identify potential scam text, emails, and links.
What sets Norton apart is how it handles false positives. When it blocks a site, you get a detailed explanation of why, along with the option to proceed if you’re certain it’s safe. The app learns from your choices, reducing unnecessary warnings over time without compromising security.
Pro Tip: We recommend turning on Norton’s Safe SMS feature. It automatically detects and blocks scam text messages. In our testing, it caught 94 percent of phishing texts.
Our Experience With Norton Mobile Security
After three months of daily use, Norton proved itself as the most comprehensive iPhone security solution available. The app blocked every threat we threw at it while maintaining minimal impact on battery life (less than 3 percent daily).
This level of protection is ideal for anyone who handles sensitive information on their phones, like business owners or healthcare workers. It’s even useful for anyone who uses their iPhone for mobile banking. If you’ve ever been a victim of identity theft or you’re storing confidential client data on your device, Norton’s protection is worth every penny.

Norton VPN (starting at $39.99) is a no-nonsense VPN with servers in over 100 cities. Norton Antivirus Drawbacks
These premium features come at a premium price, and it might not be worth it if you’re already careful about your online habits. Pricing for Norton Mobile Security is $19.99 for the first year. If you want Norton Deluxe, which includes all the security features, it will cost you $49.99 for the first year.
You’ll notice that we said “for the first year”. That’s because, like most Norton subscriptions, the prices increase when it’s time to renew your subscription. Norton Mobile Security renews at $29.99 per year and Norton Deluxe is $119.99 per year.

2. TotalAV Antivirus - Best Value for Money
View Packages Links To TotalAV
Product Specs
Virus Detection Yes Malware Detection Yes Firewall No Full, quick, and scheduled scans Yes Real-time protection Yes Behavior-based monitoring No
TotalAV delivers impressive protection at nearly half the cost of a Norton Deluxe subscription. The breach monitoring caught the same data leaks as Norton did, and TotalAV’s VPN is surprisingly robust. Despite TotalAV increasing the price of the renewal subscription, we still feel like we’re getting a similar level of security compared to Norton Antivirus.
What We Like
- Strong protection at about half the cost of Norton
- Breach monitoring catches the same leaks as pricier competitors
- VPN is fast and reliable, even on overseas servers
What We Don’t Like
- Sends unnecessary notifications that feel like upselling
- Customer support is slower than Norton
- Identity monitoring is limited to email addresses only
Getting Started With TotalAV
We found TotalAV’s setup process refreshingly straightforward. The app guided us through three main steps: enabling WebShield protection, setting up the security scanner, and configuring breach monitoring. The entire process took less than three minutes, making it the fastest setup among the apps we tested.
One unique feature that stood out is the security audit, which scans your device for potentially harmful apps and suspicious profiles. In our case, it identified an old VPN profile from a free service we’d tested and forgotten about.

TotalAV Web Protection
The WebShield feature blocked 97 percent of malicious sites in our testing. That’s slightly lower than Norton, but still impressive for the price point. Where TotalAV really excels is in its handling of suspicious downloads and email attachments. The app prevented us from opening three malicious PDF files that came through legitimate-looking emails.
We also like that when a threat is blocked, you get a clear explanation and useful tips on how to protect yourself from similar threats.
Here’s the TotalAV settings page where we did most of the customizations to make sure it gave us enough malware protection Our Experience With TotalAV
While not as comprehensive as Norton, TotalAV’s breach monitoring covers the essentials well. It checks your email addresses against known breaches and alerts you within 24 hours of new exposures. During our TotalAV testing, the app identified five historical breaches involving our email addresses, complete with what type of data was compromised.
Unlike some other antivirus apps we tested on iPhone, TotalAV includes system optimization tools. The duplicate photo finder freed up 3 GB on our device by identifying nearly identical images and videos. The battery optimizer also provided genuinely useful suggestions that helped extend our daily battery life by about 15 percent. These extras might seem gimmicky, but we found that they add real value.
Pro Tip: In addition to system optimization tools, Total AV has a password manager that also lets you save credit card information and documents. Check out our Total Password review to learn more.
TotalAV Drawbacks
During our testing, we noticed a lot of unnecessary notifications that felt more like upselling than actual security alerts. We also reached out to the customer support team and found the response times averaged 24 to 48 hours compared to Norton’s instant chat.
Another similarity TotalAV shares with Norton is renewal costs. The price increases from $29 in the first year to $99 per subsequent year. The jump is huge, but at the end of the day, it’s still cheaper than Norton’s Deluxe plan.

3. Guardio - Best for Scam Detection
View Plans Links to Guardio
Product Specs
Virus Detection Yes Malware Detection Yes Firewall No Full, quick, and scheduled scans No Real-time protection Yes (browser-based) Behavior-based monitoring Yes
While its desktop service restricts you to Chrome or Edge, Guardio’s iPhone app is compatible with any browser on your phone. During our testing, it blocked all phishing links we attempted to open. What stood out most is how it uses AI to detect online scams, which is a feature not many antivirus apps offer.
What We Like
- AI-powered threat detection
- Instantly blocks malicious sites
- Affordable pricetag
What We Don’t Like
- Lacks extras like VPN and identity theft protection
- Monthly pricing is more expensive than competitors’ annual plans over time
- The app doesn’t always tell you what it’s doing
Getting Started With Guardio
We downloaded the Guardio – Mobile Security app from the App Store and followed a few simple steps to get it up and running. During testing, Guardio blocked all test malware downloads, although it missed malicious viruses hidden in zip files.
Guardio regained our trust with its protection against online scams. Guardio blocked every fake virus warning and bogus page we encountered. The app uses AI to identify threats, similar to Norton’s Genie Scam Detector. For older adults or those less familiar with online scams, this feature alone justifies the subscription.

Guardio Web Protection
Guardio works with all browsers on iPhone, including Safari. That’s noteworthy because when we tested it on desktop, the web protection features only worked with Chrome and Microsoft Edge. Those are the only two browsers that have native extensions for Guardio.
Guardio’s email protection feature was more active. The app scans links in your emails before you click them. During testing, it caught several phishing emails that made it past Gmail’s spam filters, including a convincing fake Amazon order confirmation.
FYI: Guardio also provides email leak monitoring, though it’s more basic than dedicated identity monitoring services. It checks if your email appears in new data breaches and sends immediate alerts.
We recommend connecting your Gmail account to block phishing emails and scam messages.
Our Experience With Guardio
Guardio is great at detecting malware and phishing attempts, but it’s not so great if your iPhone is already infected. The app can’t remove or quarantine files like Norton or TotalAV can. Guardio takes a preventative approach by telling you not to click on links or open suspicious files.
We also recommend checking in on the app regularly. We received a push notification when we tried opening a website flagged as suspicious, but Guardio allowed us to access it again minutes later.
Guardio Drawbacks
We like that Guardio offers plans for individuals, duos, and families. The only issue is that the prices are more expensive than many competitors. Here’s an overview of Guardio’s prices:
Free Individual Duo Family Users 1 1 2 5 Monthly Cost Free $14.99 $11.50 $7.00 First Year Cost Free $119.88 $189.90 $279.90 Considering Guardio is lacking a VPN and identity theft protection features, these prices are high. What you will get instead is reliable malware and phishing protection, powered by AI.

Do iPhones Really Need Antivirus?
Traditional viruses can’t infect iPhones through normal use thanks to iOS’s sandboxing architecture. This means apps run in isolation, which prevents one app from affecting another or the core operating system.
Modern threats like phishing attacks, malicious websites, and data breaches can still break through defenses. These attacks target you, not your operating system, tricking you into revealing passwords or financial information. We think installing antivirus protection on your iPhone is worthwhile because these threats still exist.
FYI: 71% of organizations experienced successful phishing attacks in 2023, according to Proofpoint’s State of the Phish report.2 These attacks work just as well on iPhones as any other device because they exploit human psychology, not technical vulnerabilities.
What Threats Do iPhone Antivirus Apps Protect Against?
Many iPhone security apps protect against web-based threats that Apple’s built-in security doesn’t address. This includes:
- Phishing websites designed to steal your credentials
- Malicious ads redirecting to scam sites
- Public Wi-Fi networks capable of intercepting your data
- Data breaches where your information has been leaked
Security apps can also protect against juice jacking (malware installation through public charging stations), which authorities continue to warn users about.3 While these attacks are less common than simple phishing, they’re increasing as criminals become more sophisticated.
Expert Tip: Even with security apps installed, never enter passwords or financial information on sites you reached through email links. We recommend navigating to the site directly instead. For additional protection, use a password manager.
Do Antivirus Apps Slow Down Your iPhone?
Modern security apps have minimal performance impact when properly designed. In our testing, Norton, TotalAV, and Guardio all used less than three percent of daily battery life and added no noticeable lag to web browsing or app launches. The key is choosing apps that use cloud-based scanning rather than storing massive threat databases locally.
We normally recommend antiviruses that offer real-time protection, but not when it comes to iPhones. Apps that require constant background scanning on iPhones or those that aren’t regularly updated cause significant battery drain and performance issues. Before you download anything, we recommend checking the App Store reviews for recent complaints about performance.
Recap: Are iPhone Antivirus Apps Worth It?
Mobile security isn’t just about scanning for viruses. It’s about protecting yourself from sophisticated attacks that no operating system can prevent. Whether you choose Norton’s comprehensive suite, TotalAV’s balanced approach, or Guardio’s focused AI-powered protection, you’re adding a crucial layer of security that Apple doesn’t provide.
We believe Norton Mobile Security offers the best iPhone antivirus protection for most users, combining superior threat detection with comprehensive identity monitoring. TotalAV offers remarkable value for budget-conscious users, delivering robust protection at half the cost. Guardio provides focused web protection perfect for users who primarily need safe browsing. Your iPhone might not need traditional antivirus, but in today’s threat landscape, it definitely needs extra protection.
