Protection that stops it,
undoes it, and explains it.

Signature-free antivirus for Windows. A machine-learning engine that catches new threats — not just the ones already on a list — and is built to almost never flag the software you actually use.

Why it's different

Most antivirus recognises threats it has seen before. Digital Defender judges behaviour and structure — so it can stop things no list has caught yet, without turning your PC into a nag machine.

◎

Signature-free

A modern machine-learning model scores each program on what it is and does — catching brand-new and repacked malware that signature lists miss.

✓

It doesn't cry wolf

Tuned relentlessly for a very low false-positive rate. Your games, dev tools and niche utilities keep working — a false alarm that breaks your software is treated as a release blocker.

◇

Radically transparent

Every decision is written to a plain-text log you can read. When it phones home, it writes exactly what it sends to a file first — so you can see precisely what leaves your machine.

♦

No dark patterns

No bundled extras, no scare-popups, no price traps. One-click, leave-nothing-behind uninstall. It runs happily alongside Windows Defender.

Stops it. Undoes it. Explains it.

Stops it

Watches programs the moment they start and blocks the ones it judges malicious — before they run, not after the damage.

Undoes it

The roadmap headline: reverse the damage a threat did, so a bad click doesn't have to mean a lost afternoon or a ransom demand.

Explains it

Plain-English incident cards tell you what happened and why — no jargon, no acronym soup, no guesswork.

Been protecting PCs for a long time

Digital Defender isn't new. It has been guarding Windows machines since 2006, and earned VB100 certifications — the independent lab test that measures whether an antivirus actually catches malware without false alarms — back when that was the bar to clear.

Today it's being rebuilt from the ground up around a signature-free machine-learning and behavioural engine: the same trustworthy name, a detection approach fit for how threats work now. The heritage is real; the engine is modern.
