Can iPhones Get Viruses?
YES, absolutely! But it is highly uncommon due to the iOS ecosystem. They thoroughly examined third-party apps before allowing them to be available on Apple’s App Store, ensuring the security of your device.
With that said, you can’t install apps that aren’t from the official app store unless you jailbreak your device, which makes it vulnerable to viruses.
Jailbreaking is modifying your iPhone with software that bypasses security restrictions to install unfamiliar apps.
How to Check for Viruses on Your iPhone
If you suspect your iPhone has been acting strangely recently due to app freezing, battery draining quickly, or other reasons, your iPhone might be likely infected with viruses.
Keep an eye out for these virus warnings to ensure your iOS devices have phishing, ransomware, data breach, or malware threats before attempting to remove iPhone viruses.
Having pop-ups in Safari or other browsers installed on your phone is usual because of ads. But if it frequently appears inside and outside your browser, it usually indicates that you may have acquired phone viruses.
Your iPhone is Getting Too Hot
Your phone can sometimes be hot due to weather, faulty battery, streaming high-quality videos, or too much data usage. But malicious apps may also consume many CPU and memory resources that cause overheating. If your phone is constantly overheating, a virus is a possible culprit.
Unexpected App Crashes
App crashes occur when your active application abruptly closes or ceases to function. Some causes include running out of storage space, a slow internet connection, having too many apps open simultaneously, and failing to install updates. If one of the reasons listed above is not the case, your device might be likely infected with malware.
You See Unfamiliar and Suspicious Apps
If you own a smartphone, you are probably used to downloading apps. Check all your downloaded apps to see if they were pre-installed or if you have downloaded all the apps yourself. If you find unfamiliar apps, it may be a sign that your device is infected with malware.
The Battery is Draining Quicker Than Usual
Malware threats can drain your battery by consuming significant processing power transferring and uploading data, or adding more malware in the back end. Look for changes in patterns in your device’s battery health to check if it possibly has a malware infection.
Increased Data Usage
Opening multiple apps may lead to increased data usage. Too much data usage, even when you’re not using multiple apps simultaneously, may indicate that your phone is infected with malware.
The Device is Operating Slowly
Your device can run slow if it is low on storage space or the operating system needs to be updated. If these cases are not true for you, it might be a phone virus.
Jailbroken iPhones bypass the official app store – Apple to install unknown apps. It makes it easier for malicious software to infect devices with malware threats and make them vulnerable to other threats.
Unidentified Charges on Your Account
If you have unknown fees in your bank statement and/or you find that some other signs listed above are true for your iPhone, it is possible that your device has been compromised. An iPhone malware might have accessed your banking or financial information.
