    62.6

    score / 100

    Why switch from ClamXAV

    Free, open-source Mac tool that flags new persistent software as it's installed.

    Pros

    • Catches persistence attempts as they happen instead of after a scheduled scan
    • Alerts show the responsible process, signing details and VirusTotal results
    • Free and open source, made by a non-profit with a long Mac security track record

    Cons

    • Does not detect or remove known malware the way a scanner does
    • Alerts for legitimate installers need judgement from the user
    • macOS only, and requires Full Disk Access and system privileges

    score / 100

    Why switch from ClamXAV

    Free Mac scanner for reviewing startup items when a subscription antivirus feels like too much.

    Pros

    • No installation; run it from anywhere and delete it when done
    • Clear signed, third-party and unsigned markers make odd items easy to spot
    • Optional VirusTotal checks with a free personal API key

    Cons

    • On-demand only, with no real-time protection
    • Lists legitimate apps alongside threats, so results need interpretation
    • Runs only on macOS
