Bitdefender Antivirus Free for Android review

Bitdefender Antivirus Free for Android does one job: it keeps malicious apps off the phone. It scans every app the moment it is installed and lets you run an on-demand scan of apps and storage whenever you like. Detection runs in Bitdefender's cloud rather than on the device, so there are no signature downloads and Bitdefender says battery impact is close to zero. The company says the free app uses the same scanning engines as Bitdefender Mobile Security, its paid app. There is nothing to configure, which makes it a good pick for a parent's or grandparent's phone. What it does not include is the layer that catches scams. The free product page lists malware scanning only, while web protection, scam protection across texts and chat apps, call blocking, anti-theft and a 200 MB per day VPN are on the paid Mobile Security page. That upgrade costs $17.99 for the first year, the lowest paid price we found here.

Who it is for
