How Antivirus Can Help Protect Your iPhone
iPhones already have strong built-in security features, so you might wonder what an antivirus app can add.
iOS uses sandboxing to keep third-party apps separated, helping protect the wider system and information stored in other apps. For this reason, antivirus apps work differently on iOS than traditional antivirus software does on some other devices.
An antivirus app can complement the iPhone's built-in protections with extra online security and privacy tools. These may include web and phishing protection, a VPN, unsafe Wi-Fi alerts, password management, and identity or data-breach monitoring.
What Security Threats Affect iPhones?
While iOS provides strong security, iPhone users can still face scams, privacy risks, stolen passwords, and other online threats.
Features included with some of the best antivirus for iPhone options may help address several of these risks by providing added online security, privacy tools, and alerts.
Phishing and Text-Message Scams (Smishing)
Phishing happens when a scammer pretends to be a person or organization you trust. The goal is often to convince you to share a password, payment information, or other personal details.
On an iPhone, phishing attempts may reach you through:
- Email
- Social media
- Messaging apps
- QR codes
- Text messages
Phishing through text messages is commonly called smishing.
Scams can also be harder to spot on a small phone screen because you may not see the full website address or other warning signs. Some iPhone antivirus apps may warn you about known phishing links and websites. However, no app can detect every scam, so it is still important to check unexpected messages and links carefully.
Compromised Online Accounts
Apple's built-in security cannot prevent a company from experiencing a data breach. If your email address, password, or other information is exposed, a criminal may try to use it to access your accounts.
Identity and breach-monitoring tools, which are included in certain antivirus apps, may alert you if your information appears in a known data breach. This warning gives you an opportunity to change affected passwords and check your accounts for unusual activity.
Unsafe Wi-Fi Networks
Public Wi-Fi in airports, hotels, cafes, and other shared spaces may not always be secure. Some networks can also be fake and set up to trick people into connecting.
A VPN, a feature included in some third-party antivirus options, encrypts the internet traffic between your iPhone and the VPN provider's server. This may provide greater privacy when you use public Wi-Fi. Still, a VPN feature within an antivirus package does not protect you from scams, unsafe downloads, or malicious websites.
Malicious Websites and Online Scams
Some websites are designed to steal passwords, payment details, or other personal information. Others may show fake security warnings that try to frighten you into calling a fraudulent support number, paying for an unnecessary service, or installing an untrustworthy app.
Some iPhone antivirus apps offer web protection that can warn you about dangerous websites. It is still important to be careful with unfamiliar links, attachments, and requests for personal details.
Weak or Reused Passwords
Using the same password for several accounts can increase the potential impact if one of those accounts is compromised. Weak passwords may also be easier for criminals to guess.
Some iPhone antivirus packages include a password manager that can create and store strong, unique passwords. Others may provide alerts if a monitored password or email address appears in a known data breach. Features vary by provider.
Keep Your iPhone Updated
Antivirus apps can add useful online security and privacy tools, but they do not replace iOS updates. Keeping your iPhone updated helps ensure that it receives Apple's latest security fixes.
How to Choose the Best Antivirus for iPhone
With these potential risks in mind, consider which extra security and privacy features would be most useful to you. The following factors can help you compare antivirus options for your iPhone.
iOS Compatibility
Check that the app supports your current iOS version and confirm which advertised features are available on iPhone.
Features can differ across operating systems. For example, a provider may offer malware scanning on computers but focus on web protection, a VPN, and identity monitoring on iPhone.
Web and Phishing Protection
Because antivirus apps cannot scan an entire iPhone, web and phishing protection may be among the most useful features to compare.
Look at how the app handles suspicious websites and links. Also, check whether its protection works only in Safari or covers other browsers and apps.
VPN and Privacy Features
If a plan includes a VPN, consider comparing:
- Privacy practices
- Server locations
- Connection speeds
- Data limits
You may also want to check whether you can use its VPN and web protection at the same time.
A VPN can improve online privacy and help secure your connection on public Wi-Fi. However, it cannot protect you from every scam, malicious website, or form of tracking.
Identity and Breach Monitoring
Some antivirus plans include monitoring that checks whether email addresses, passwords, financial information, or other personal details appear in known data breaches.
Check which information the service monitors and how it sends alerts. If a plan includes identity-theft assistance or insurance, confirm its availability and terms where you live.
Brand Reputation and Privacy
A provider's reputation and privacy practices are important factors to compare. Before downloading an app, use the provider's website to find its official listing in Apple's App Store.
You can also review its privacy policy to understand what information it collects, how it uses that data, and whether it shares information with other companies.
Multi-Device Coverage
A multi-device plan may provide better value if you also want protection for a Mac, Windows computer, Android phone, or devices belonging to other household members.
When comparing plans, consider how many devices they cover and which operating systems they support. Keep in mind that the iPhone app may not include every feature available on a computer or Android device.
Battery Life and Performance
An app that filters internet traffic, checks network connections, or runs a VPN may affect battery life or internet speed.
The impact can depend on:
- Your iPhone model
- iOS version
- Network connection
- Which features you turn on
Recent independent tests and verified buyer reviews may provide more information about an app's performance.
Ease of Use and Customer Support
Having clear settings and alerts that are easy to understand could be important to you. If so, you may look for an antivirus that provides notifications explaining the possible risk and options for what to do next.
You may also want to compare the available customer support. Depending on the provider, support may be offered by phone, email, live chat, or online help pages.
Value
What features are most important to you, and which ones in an antivirus package do you plan to use? A large bundle may not offer good value for you if many of its features are not ones you expect to use or do not work on iOS, for example.
