Mobile Security & Antivirus by Lookout is an all-in-one mobile security and antivirus app that provides premium protection for Android devices. With Lookout, users can protect their devices from viruses, malware, and spyware, and rest assured that their personal data is safe with ID theft protection services. Lookout Basic includes features such as virus scanning, system advising, and location mapping, while Lookout Antivirus & Security Premium offers additional features like safe Wi-Fi, breach reporting, and theft alerts. Lookout Premium Plus (US only) provides all of the Premium functionality, as well as identity theft protection.

One of the key features of Lookout is its virus scanning capabilities. The app provides continuous, over-the-air antivirus protection from viruses, malware, spyware, adware, and phishing. Users can simply scan their device and Lookout will take care of the rest. Lookout also checks mobile devices for root detections to ensure that the operating system is working properly. In addition, Lookout makes it easy to identify, clean, and remove viruses from Android devices.

Another important feature of Lookout is its location mapping and theft alert capabilities. Users can map the location of their device and make it sound an alarm, even on silent. Signal Flare automatically saves the device's location when the battery is low. In addition, Lookout sends an email with a photo and location whenever suspicious behavior is detected that could mean the user's identity has been stolen.

Lookout Antivirus & Security Premium offers additional features such as safe Wi-Fi, breach reporting, and safe browsing. Safe Wi-Fi protects mobile data from phishing and other Wi-Fi attacks, while breach reporting provides timely alerts whenever a company, app, or service the user uses has a data breach. Safe browsing scans every URL link the user visits to help detect online threats with antivirus technology and alert them of sites that can infect their device and steal their personal information. Privacy Advisor allows users to see what personal information can be accessed by their apps, while Lock & Wipe allows them to remotely lock their device, post a custom message, and erase their data.
