Online Security

Avast Mobile Security is a comprehensive Android antivirus app with an excellent free version and two fully-featured paid options.

Norton 360 for Mobile provides everything you need to secure your Android phone or tablet except for a free version.

Google Play Protect comes preinstalled on most Android devices to keep you safe from malware, malicious apps and more for free.

Bitdefender Mobile Security is the best overall choice for mobile protection with excellent malware defenses, low-overhead scanning and plenty of useful extra features.

Sophos Home Premium provides decent protection against malware for a fair price but lacks many commonplace antivirus features.

Trend Micro provides good malware protection with a number of useful extras but false positives and system slowdowns during scans can be annoying.

McAfee's antivirus lineup is a steal for large families but its malware protection and system impact leave a bit to be desired.

Microsoft Defender comes pre-installed and pre-enabled on all Windows PCs but it’s also a very capable antivirus with good protection and a tamper resistant design.

ESET's security software is fast, accurate and thorough. It lacks some extra features we take for granted but has a very light impact on your system performance.

Norton 360 Standard, Norton 360 Deluxe and Norton 360 with LifeLock include the most complete antivirus-software and identity-protection-service combinations you'll find today.
