Digital Defender

Windows security software. Rebuilt from scratch, in progress.


Field check (beta)

A measurement tool we are asking a small number of people to run. It looks at the software already installed on a PC and records what our detection engine would have said about each program, so we can find out where it gets things wrong on real computers rather than only on ours.

It does not block, quarantine or change anything, installs nothing, and leaves nothing running. It is not antivirus and provides no protection — anyone running it should keep using their existing security software. It sends one report, after asking, and writes a copy to the Desktop so you can read exactly what was sent.

To check the download is the file we published, run this in PowerShell and compare it with the hash above:
Get-FileHash ddcheck.zip -Algorithm SHA256

The README inside explains what it does, what it sends, and how to verify all of that yourself rather than taking our word for it. If you would rather it sent nothing at all, it takes a --no-upload switch and will keep the report entirely on your machine.
