Its user-friendly, clean interface and lack of ads contribute to its popularity. The free version of the app comes with basic features, such as scanning for malware and blocking phishing websites.
McAfee Mobile Security, another excellent antivirus program. Its ‘anti-theft’ features are powerful, letting you track down the stolen device remotely and lock it or wipe its data.
