It’s fair to say we live on our smartphones and tablets. They allow us to browse the web, connect with people via social media, capture photos and videos, keep up-to-date with the news, play games, stream movies and music, and much more.
But despite playing a significant role in our daily lives and offering a wide range of benefits, mobile devices are increasingly vulnerable to online security risks. Without appropriate protection, mobile devices can expose users to viruses, malware, spyware, ransomware, hacking, data breaches, and other cyber threats. Simply clicking on a dangerous link or downloading a malicious app can have disastrous consequences.
While the thought of your smartphone or tablet being impacted by one of these threats is scary, you can easily boost the security and privacy of your mobile devices by installing an antivirus solution. The best mobile antivirus apps are capable of identifying and tackling a range of online security threats, from malicious software to unauthorized user access.
Luckily, there are loads of mobile antivirus apps available for both Android and iOS devices today. But, which app should you download? To help you choose the right one for you, we’ve ranked the best mobile antivirus apps of 2021.
Norton Mobile Security is a popular antivirus app that protects against a range of cyber threats in order to improve the privacy and security of your smartphone or tablet PC.
Available for Android and iOS devices, it offers four main features: an app advisor, Wi-Fi security, web protection, and device security.
App Advisor uses patented app scanning technology to mitigate malware, ransomware, adware, and privacy threats. The app also employs Wi-Fi protection to identify dangerous or breached networks. In contrast, web protection detects and warns you about any fraudulent or malicious websites you’re about to access from a web browser, text message, email account, social networking site, or mobile app.
As well as offering protection against external online security threats like malware and dodgy websites, Norton Mobile Security also provides device security for detecting whether your smartphone or tablet is using an outdated operating system. That way, you can update it to the latest version and eradicate any serious security issues affecting your device.
