What Mobile Antivirus Does
Mobile antivirus solutions are specifically tailored for smartphone environments (Android and iOS) and may help safeguard your device by identifying malware, spyware, ransomware, or malicious apps, depending on the operating system and app. Some can also run background checks with limited impact on system performance.
In addition to regular email-based phishing protection found on desktops, mobile antivirus apps may help identify or block malicious links in SMS, social media chats, and even QR codes. Some can also block malicious ads for added browser protection. Many top antivirus solutions include device cleanup tools that remove unnecessary clutter and may alert you to security risks on compromised or unsecured public Wi-Fi networks.
Other mobile-specific features include anti-theft tools to track, lock, or wipe data from a lost or stolen device. Some also bundle extra cybersecurity tools such as a password manager, a VPN, and dark web monitoring to provide all-around protection for your phone.
What Threats Are Relevant on Phones
Mobile phones are a common target for threat actors, who may try to compromise them using various methods.
Malicious Apps or Downloads
Like desktops, you may accidentally download and install a malicious application or file on your smartphone that ends up infecting your device with a virus, malware, or spyware and stealing personally identifiable information, causing data theft.
Suspicious App Permissions
Data theft can also occur through apps that look legitimate but request permissions they don’t need to function. For example, a wallpaper app shouldn’t need access to your contacts or storage. An application requesting permissions beyond its purpose is an important red flag to watch out for.
Operating System Vulnerabilities
Your phone’s operating system (Android or iOS) can also introduce new vulnerabilities over time. That’s why manufacturers regularly roll out bug fixes and security updates. However, in rare cases that threat actors discover those vulnerabilities first, your device could be exposed to risk.
Man-in-the-Middle (MitM) Attacks
Mobile devices can be vulnerable to man-in-the-middle (MitM) attacks, where attackers position themselves between two devices that believe they’re communicating securely. The victim may unknowingly hand over sensitive credentials or personal information.
The risk is higher when an app uses unencrypted HTTP connections or when communication happens over SMS messages, which are typically not encrypted. MitM attacks usually occur when mobile phones connect to unsecured Wi-Fi networks, such as those in cafes, airports, or hotels, which may increase exposure to attackers.
Phishing Scams
In a phishing scam, a cybercriminal poses as a trusted entity such as your bank, a delivery partner, or even a known contact and lures you into clicking a malicious link and sharing sensitive information including login details, Social Security numbers, and banking details.
Although phishing scams aren’t exclusive to phones, mobile devices provide more avenues for attackers to carry them out, including:
- SMS messages (called smishing)
- Social media platforms
- QR codes
- Dating apps
What’s more, phishing sites can be harder to spot on the limited screen real estate of mobile phones, and you may miss details such as misspelled URLs or obvious grammatical errors on the site.
Data Leak from Legitimate Apps
Even data you share with legitimate apps or companies can be exposed or stolen by cybercriminals. This may happen if the company, which is otherwise trusted and reliable, ends up being compromised by a data breach.
Mobile Antivirus: Android vs iPhone
In a nutshell, Android users should look for both strong on-device protection and tools that defend against online threats. iOS users already benefit from stronger built-in on-device protections, so they can prioritize robust online security features in a mobile antivirus solution.
Let’s take a closer look at this difference:
Android
One of the fundamental differences between these two ecosystems is that Android follows an open-source model. While this provides certain advantages, such as flexibility and versatility, differences across Android devices and apps can also create different security considerations.
Furthermore, since the Android operating system is used by several mobile manufacturers, there can be significant variation in update frequency and in how much each manufacturer prioritizes security. Android also allows users to easily sideload apps onto their phones. While you should always ensure an app comes from a legitimate source, installing apps from untrusted sources can increase the risk of installing malicious apps and target Android users with malware, viruses, ransomware, spyware, and adware.
That is why comprehensive, real-time scanning and on-device protection, as well as app permission monitoring, are major features of Android antivirus software. Once that’s covered, look for robust protection against phishing, Wi-Fi network monitoring, and data breach alerts.
iOS
Apple keeps much of its iOS source code proprietary, which can make some of the underlying code less directly accessible to potential attackers. The iOS operating system offers standardized experience, which reduces the risk of security gaps from a manufacturing perspective. Apple also provides security updates to address newly discovered vulnerabilities and bugs.
Moreover, iOS has a sandboxing architecture, which helps isolate apps from each other and restricts their access to the operating system and system resources. So even if a particular app develops issues, it typically won’t affect other apps or the phone’s operating system.
However, this does not make iOS users immune to security threats. As a result, iOS antivirus solutions tend to focus more on online attack vectors such as phishing via email or SMS, data breaches, malicious websites, and identity theft. Some iOS security solutions also include extra cybersecurity tools like a VPN.
How to Choose the Best Mobile Antivirus for You
We’ve identified the most important factors to consider when looking for the best antivirus for mobile.
Compatibility
First things first, you should check whether the antivirus software you’re considering is compatible with your specific mobile device and OS version. Many antivirus apps support a range of OS versions, but it is still important to check compatibility before subscribing.
Real-World Detection Rates
In our opinion, this is one of the most important factors to consider. Independent testing or other evidence can show how well a mobile antivirus detects relevant threats and whether its claims are backed by real-world performance results. Protection against the latest threats, including newly identified malware and phishing threats, is also important.
Brand Reputation
Reputable antivirus brands with a history of strong detection rates and attention to user privacy may be worth considering. Antivirus apps are typically available through the brand’s official website, Google Play Store, or Apple App Store. Apps from untrusted sources may carry additional security risks.
Extra Features
Beyond core security features, various scan types, and minimal impact on system performance, look for solutions that cover broader security needs, both offline and online. Useful extras include:
- A firewall
- Password manager
- VPN
- Dark web monitoring
- Device cleanup tools
- Phishing or scam protection
Multi-Device Coverage
You may get better value by choosing a subscription that covers multiple devices, including both mobile phones and desktop PCs (macOS and Windows). This lets you protect not only your own devices but also those of other household members.
Ease of Use and Support
The amount you shell out for your mobile antivirus subscription will depend largely on your requirements. If you're looking for a good bargain, you may find it in subscriptions that cover a limited number of devices or offer only the core essentials.
However, if you want something closer to a full-blown internet security suite and would also like to protect your entire household, you may have to spend a few extra bucks. Your budget, the features you need, and overall value for money are all useful factors to consider.
