Certo AntiSpy vs ClamAV

Certo AntiSpy is an Android security app that scans for spyware, stalkerware, viruses, trojans, and other suspicious activity. Checks include keyloggers, rooting, device administrator privileges, and apps using accessibility features to monitor activity. Most detected threats can be removed with one tap; cases needing manual action come with instructions. Intruder features can alert users to access attempts, trigger an alarm, or secretly take a photo. A privacy audit identifies apps using sensitive permissions, including camera, microphone, and location, so users can revoke access. Breach Check searches the dark web for accounts or passwords that may have appeared in data breaches. Premium Plus includes Certo Secure VPN, which the product page says encrypts browsing connections, including on public Wi-Fi. Certo says scan analysis happens locally, files and app data are not uploaded to its servers, and removal requires user approval. The Android app runs on phones and tablets with Android 7.0 or later and does not require a computer to scan. The free AntiSpy plan costs nothing and includes spyware detection, threat removal, and a privacy audit. Paid monthly plans are $4.99 a month for Premium and $8.99 a month for Premium Plus; Premium yearly is $27.99 a year.

ClamAV is a free, open-source antivirus engine for email and web scanning and endpoint security tasks. It provides a multi-threaded daemon, a command-line scanner and a tool for automated virus database updates. The database receives updates multiple times per day, and the updater supports scripted updates and digital signatures. ClamAV scans standard mail formats and many archive, executable and document formats, including MS Office, HTML, RTF and PDF. A Milter interface supports Sendmail. On modern Linux versions, ClamOnAcc can scan files when accessed, with an option to block access until scanning finishes. Signed signature databases limit execution to trusted definitions. The project lists GNU/Linux, FreeBSD, macOS and Windows as regularly tested platforms, and official Docker images are available for Alpine Linux and Debian Linux. ClamAV is an engine and associated tools, not a traditional antivirus or endpoint security suite. Recommended minimum resources are 3 GiB RAM, a 2.0 GHz CPU and 5 GiB of free disk space. The project does not guarantee extraction of every version or variant of supported formats.
