If you have an Android mobile phone, it's a great idea to run an online antivirus scan on a regular basis to keep viruses away from your device. They can cause destruction to your phone, from stealing personal information to sending premium-rate texts. The best online antivirus scan for Android mobiles is one that's quick, easy to use and has the highest malware detection rating.

Malwarebytes Premium is the best protection overall, with top scores from AV Comparatives and AV Test. The app also has an easy-to-use interface and does not contain ads. It offers a wide range of features, including malware scanning for apps and files as well as anti-theft and call blocking as well as a link checker that is useful for protecting against harmful websites, Wi-Fi networks scanning and a privacy guide.

Bitdefender is another great choice with a clean and simple interface without ads and an extremely high malware detection score. Its free tier is a bit basic, offering only a few features when compared to the paid version but it's still a great alternative.

Kaspersky Mobile Antivirus, another popular choice, comes with powerful anti-theft features and a clean interface that is free of ads. The paid version comes with an app lock that automatically scans new apps and other advanced features.

Norton Mobile Security is my favorite overall antivirus app for 2023. It has the best mix of malware protections and other safety features, including a password manager and a safe web browser. It's pricey but you can try it for 14 or 30 days.
