If your iPhone is acting slower than usual or its battery drains way too fast, it’s worth checking to see if malware has somehow snuck onto your smartphone.

Apple’s iPhone is known for its security, thanks to its closed ecosystem and strict App Store regulations. It rejects millions of apps that breach privacy, security and content standards and protects users from thousands of dodgy apps. However, your iPhone isn’t completely immune to malware.

It can be tricky to determine if your iPhone is infected with malware. The good news is there’s an easy way to detect any malicious software on your device.

This guide will help you discover the best ways to scan your iPhone for malware using reliable antivirus software.

How to scan iPhone for malware

Follow the steps below to find out if there is any malicious software on your iPhone. We recommend following each step, as different kinds of malware can be difficult to spot. If you find any unfamiliar apps that you don’t need, make sure to uninstall these iPhone apps safely.

Check for unfamiliar apps

There are over a million apps on the Apple App Store, and the average iPhone user may have dozens of apps that they downloaded and barely use. Hackers can take advantage of this in a few ways, including changing the app’s image or title and hiding it in your iPhone’s App Library.

Scroll through all your iPhone apps in the App Library and check for unfamiliar apps you don’t remember installing.

Check your battery life

Malware is known to use your device’s resources in the background, making it harder for users to detect malicious activity. On a mobile device like an iPhone, this can deplete its daily battery life. If your iPhone’s battery life is running out sooner than expected, it’s worth checking Battery settings to see if an app is causing the issue.

Head into Settings > Battery to check if any unfamiliar apps are consuming a high amount of your iPhone’s battery life.

Watch out for pop-up ads

While pop-up advertisements are inevitable in apps and browsers when scrolling through websites, seeing too many is concerning.

If an app or website keeps redirecting you to different web pages and installing unwanted toolbars, extensions or plugins, it could be a sign of adware on your iPhone.

Use antivirus software on iPhone

Simply put, the best way to scan for malware on iPhone is to use the best antivirus software.

Many free malware removal apps will dispatch malicious software on your device. Still, it’s a good idea to ensure these tools are trustworthy, as hackers can also disguise these apps on the Apple App Store to deploy even more malware.

The best antivirus apps come with a suite of security features that can eliminate viruses, malware, ransomware, adware, spyware or any malicious software that burrows into your iPhone. Some antivirus software, such as Bitdefender, offers security subscriptions specifically for iPhone, making it a more cost-effective option for those needing only iPhone protection.

We recommend free apps from known cybersecurity companies, including Avast One, AVG and Malwarebytes Mobile Security. These will detect and remove malware on your iPhone. Check out our thoughts on each antivirus below.

Signs of malware on iPhone

Malware can be hard to spot, as cybercriminals will do everything in their power to hide the malicious software so they can carry out their cruel acts right under a user’s nose. However, there are telltale signs that your iPhone is under attack, which may include your device’s browser (like Safari or Chrome) redirecting you to different web pages and installing unwanted toolbars, extensions or plugins. Any malware can also affect your device directly.

  • Your device is slower than usual and crashes frequently.
  • Your browser is slower than usual and crashes frequently.
  • Browsing through websites takes longer.
  • You need to recharge your device more often.
  • Apps take longer to load.
  • There’s an unknown app or software on your device you didn’t download.
  • Pop-up ads appear more frequently.
  • You iPhone is overheating.

How does iPhone get malware?

There are numerous ways malware can infect your iPhone. From adware and Trojans to ransomware and spyware, hackers use all kinds of malware to loot your personal and financial data – and all it takes is a mistaken click on a dodgy website, malicious email attachment or suspicious app on the App Store that has slipped through the cracks (such as these fake ChatGPT apps).

That being said, it is less likely for your iPhone to be infected with malware or a virus than Android phones. Apple is known for boasting a secure operating system (OS) and layers of protection on its App Store.

A popular method for hackers to infect mobile devices is through apps. There are plenty of examples of malware on Android apps, as it’s an easy way to trick potential victims into downloading legitimate-looking apps.

Thanks to Apple’s meticulous screening process before apps are made available, it’s harder for threat actors to get a malicious app on the App Store. In fact, Apple’s App Store protected users from nearly 1.7 million apps found to be breaching privacy, security and content standards, preventing over $2 billion in potentially fraudulent in 2022.

Since all apps on iPhone are obtained from the App Store and are sandboxed, Apple devices have a strong defence against malware threats. But that doesn’t make it impossible for iPhones to get malware.

Some users jailbreak their iPhones to access app stores outside Apple’s App Store. These stores don’t have Apple’s layers of protection, meaning it’s easier for hackers to distribute malware in illegitimate apps.

Can any antivirus scan and protect iPhone?

Many antivirus apps can be used to scan and get rid of malware on iPhone, but some are more trustworthy than others. Unfortunately, hackers can trick users into downloading malicious apps disguised as free antivirus apps.

To scan your iPhone for malware safely, use the best antivirus apps like Norton 360 and Bitdefender.

Antivirus software comes in the form of security apps designed to detect, prevent and remove malware on your iPhone. When installed, it will scan through everything on your iPhone, including software, applications, files and even web pages. Reliable antivirus services will notify you about suspicious software, allowing you to block or destroy emerging cyber threats.

To infiltrate a device, hackers will use different types of malware, including computer viruses, spyware, adware, ransomware, Trojans, and spam — anything that could be used to steal valuable data. An antivirus will watch and throw out malicious software that sneaks onto a device. Think of it as your personal, battle-hardened bouncer keeping unwanted guests out of your exclusive nightclub.

Some malicious apps slip through the cracks of Apple’s security. To keep your iPhone safe from malware, download the best antivirus app for iPhone.
