Can smartphones get infected with viruses or malware?
Viruses and malware are often associated with computers, like a desktop or laptop computer. However, with the increasing popularity and use of smartphones and the personal data they contain, viruses and malware have started to target the smartphones. While less common today, smartphones can be infected by a virus or malware program.
How does a smartphone get infected?
The most common way for a smartphone to get infected is by downloading an app that has a virus or malware embedded inside the app code. When the app is installed, the virus or malware infects the smartphone operating system, like Android OS or iOS.
It may also be possible for an e-mail to infect a smartphone if the user attempts to open an attachment on their smartphone and that attachment has a virus or malware. For example, an infected PDF attachment can infect a smartphone.
SMS or bad website
Another common tactic to infect smartphones is done through an SMS. For example, an unknown contact could send you a link to visit that sends you an infected attachment, attempts remote control, or attempts to phish private information from you.
How to protect your smartphone from getting infected
The best way to protect your smartphone is to only download apps from a verified, reputable source. Google Play for Android phones, App Store for iPhone, and Microsoft Store for Windows Phone are the best places to download apps. Apps in these online stores are checked for viruses and malware and much less likely to cause problems for your smartphone.
You can also download and install antivirus and anti-malware apps for your smartphone. For example, AVG Antivirus is available for Android phones, Avast SecureMe for iPhones, and Kaspersky Safe Browser are examples of apps that help protect smartphones from malware.
I heard iPhones can't get infected
Apple and other sources state that iPhones cannot get infected by viruses or malware. The iOS operating system is designed to limit access to core functionality and the ability to execute actions and code that would interact with core functionality. Doing so makes iOS more secure and less likely to get infected. However, the iPhone and the iOS operating system is not invulnerable, especially if jailbreaking or rooting is used to unlock the phone. An infection is still possible, and it is best to be careful what and where you download apps for your phone.
