How often should I scan my iPhone for malware?

Cybersecurity experts generally recommend scanning your iPhone for malware about once per week. But performing more frequent quick scans can’t hurt.

Here are some good guidelines on iPhone malware scan frequency:

Weekly – Do a full deep scan of your iPhone weekly using a free antivirus app to check for any malware or suspicious content.
After installing new apps – It’s good practice to do a quick scan after downloading new apps from the App Store, especially free apps.
If you notice odd behavior – Scan your iPhone if you notice any unusual activity like crashing, sluggishness, suspicious pop-ups, or overheating.

After visiting suspicious sites – If you accidentally visit a sketchy website on your iPhone’s browser, it doesn’t hurt to do a quick scan afterwards.
Upon receiving suspicious texts/emails – Malware is sometimes spread via phishing links sent by SMS or email. Scan your phone if you receive any messages with strange links.

Following these best practices helps ensure your iPhone remains free of malware and cyber threats.

What can I do if malware is detected on my iPhone?

If your iPhone malware scan detects any infections, here are the steps you should take:

Isolate the malware – The antivirus app should quarantine or isolate the infected file(s) so they can no longer harm your device.
Delete malicious apps – For any malware masquerading as legitimate apps, delete them immediately from your iPhone.
Remove suspicious profiles/certificates – Some malware uses profiles and certificates to bypass security. Remove any that seem questionable.

Reset your passwords – If the malware had access to your logins, reset all passwords for sensitive accounts as a precaution.
Update your iPhone – Make sure your iPhone is updated to the latest iOS version for the newest security protections.
Restore from backup – For severe infections, you may need to wipe your iPhone and restore from an uninfected iCloud backup.

Following the antivirus app’s specific remediation guidance is crucial as well. Their experts will provide detailed steps to fully remove the malware and undo any system changes.

Can I get malware just by visiting a website on my iPhone?

It is possible for your iPhone to get infected by malware just by visiting a compromised website, though the risk is relatively low. There are a few ways it can happen:

Malicious redirects – The site may redirect you to another malicious site hosting iPhone malware.
Malicious ads – Even legitimate sites can sometimes display corrupted ads that link to malware.

Browser exploits – Hackers can take advantage of vulnerabilities in the iPhone web browser to drop malware.
Social engineering – The site may trick you into downloading fake “security software” containing malware.

To reduce the chances of getting infected from a website, take these precautions:

Only visit sites over HTTPS that display the secure lock icon.
Don’t click ads or pop-ups, as these often lead to scams or malware.

Be wary of “your iPhone is infected” browser alerts that make you download apps or profiles.
Make sure your browser, iOS, and apps are all updated with the latest patches.

As long as you exercise caution when browsing on your iPhone, your risk of getting infected just by visiting a website is relatively minimal. But it’s still a good idea to occasionally scan your phone using a free antivirus tool for additional peace of mind.

Can the Apple App Store apps contain malware?

While extremely rare, it is possible for apps on Apple’s official App Store to contain malware. Apple does have protections in place to prevent this, but some malicious apps can occasionally slip through the cracks.

Here are some scenarios where malware makes it onto the App Store:

Delayed malware activation – The malware lies dormant until days or weeks after approval to bypass initial scans.

Off-the-shelf code reuse – Legitimate code packages reused by developers can unknowingly contain backdoors.
JS bridges – JavaScript bridges in some apps can be exploited to execute remote malicious code.
Runtime packers – Apps employing runtime packers prevent their code from proper inspection.

While rare, malware found on the App Store is generally removed quickly once detected and reported. To stay protected:

Only download apps from well-known, trustworthy developers with many good reviews.

Check app ratings and reviews for any mentions of suspicious permissions or behavior.
Run occasional malware scans using a trusted antivirus tool to detect iOS threats.
Keep your iPhone updated with the latest iOS version for improved malware protections.

Can jailbreaking your iPhone lead to malware?

Yes, jailbreaking your iPhone makes it significantly more vulnerable to malware. Here’s why:

It disables Apple’s security protections that prevent untrusted apps from being installed.

Opening up root access gives malware much more control over the device’s software and data.
Jailbreak app sources are not vetted or reviewed like the official App Store.
Out-of-date jailbroken iPhones don’t get important Apple security patches.

Examples of dangerous iPhone malware found spreading through jailbreak communities include:

iKee malware – Harvested and exfiltrated sensitive user data from jailbroken iPhones.

KeyRaider – Stole over 225,000 Apple IDs from jailbroken devices for fraud.
Fake Jailbreak – Pretended to jailbreak iPhones but just stole payment data.

The risks of jailbreaking are so high that cybersecurity experts strongly recommend against it. If you do jailbreak your iPhone, at the very least ensure you:

Only install jailbreak apps from completely trusted sources.
Carefully review app permissions before installing.

Regularly scan your iPhone for malware and other threats.

Conclusion

Scanning your iPhone periodically using trustworthy free antivirus apps is critical to detect and remove any malware or other iOS threats. Some reputable options include Malwarebytes, Lookout, and AVG Antivirus. Ideally, you should scan your iPhone at least weekly, and anytime you notice suspicious behavior.

While Apple’s App Store offers excellent protections, it’s still smart to scan your iPhone after installing new apps. Visiting compromised sites can also rarely lead to infections. If you do jailbreak your iPhone, that significantly increases the malware risk, so free antivirus scans become even more essential.

Make sure to follow remediation steps if your scans find any infections, like deleting malicious apps and resetting passwords. Stay vigilant and keep your iPhone’s software updated to have the best protection against the growing threat of iOS malware.
