ZeroWrite is the AI gate between arriving code and Windows memory. Intent is read, risk is scored, and the verdict lands before the first instruction executes.

ZeroWrite.ai
Every antivirus you’ve ever used shares one flaw: it works after code is running. ZeroWrite moves the decision to the only moment that matters — before.
01 — TRADITIONAL ANTIVIRUS
Signature engines let code reach memory first, then hunt for known patterns. By the time an alert fires, execution has already begun — and a zero-day has no signature to match.
02 — ZEROWRITE
ZeroWrite suspends code the instant it arrives and reads its behavioral intent with AI. The verdict lands before the first instruction runs — no signatures required, zero-days included.
Downloads, process spawns, scripts, memory injection — every arrival path runs through the same gate.
INTERCEPT
Every arrival path is hooked at the platform level and execution is suspended before the first instruction — files, scripts, and injected memory alike.
ANALYZE
The engine simulates execution pathways and scores behavioral intent, corroborated by YARA rules and SHA-256 reputation. Fully local — no cloud round-trip.
VERDICT
A risk score from Low to Critical lands within three seconds. Allow, quarantine, delete, or isolate — critical threats are dissolved automatically.
Six capabilities, one promise: code proves itself before it runs.
BEHAVIORAL AI
Execution pathways are simulated in a sandbox of one — the AI model scores what the code intends to do, even on first contact.
VERDICT: BLOCK
ZERO-DAY READY
The core engine never waits for a catalogue. Unknown code is judged by behavior alone — being new is not a pass.
CVE-????-????? — BLOCKED ON SIGHT
FILELESS COVERAGE
Memory injection and living-off-the-land techniques are intercepted exactly like files — nothing on disk, still inspected.
LAYERED ENGINE
YARA-X, hash reputation, and threat intel back the AI — extra evidence, never a dependency.
YOU DECIDE
Allow, quarantine, delete, or isolate from the network — every action logged to a local, auditable history.

Engine internals, detection write-ups, and the reasoning behind the product — written by the people building it.
Antivirus detects threats after code is already in memory. ZeroWrite suspends code at the moment of arrival, analyzes its intent, and only releases it if it passes. The difference isn’t speed of detection — it’s that execution never happens without a verdict.
The engine holds under 2% CPU at idle and under 150 MB of memory. Analysis adds up to three seconds before unknown code first runs — and nothing after that.
Yes. Behavioral AI analysis and YARA scanning run entirely on your machine. Cloud reputation is supplemental — losing connectivity never lowers your protection.
The file is quarantined before it ever executes, and an alert shows you what it was, what it intended to do, and its risk score. You can restore, delete, or isolate — every action is logged locally.
Nothing during the beta. The licence runs for 30 days from the day you install it, with no card at any point — and when it ends you keep a fortnight (14 days) of grace, then full protection without rule updates. Paid plans are listed above; a year is billed as ten months, so two are free.
Analysis is entirely local — nothing is uploaded to reach a verdict, and a file ZeroWrite allows is never copied. Files it blocks can be sent afterwards so we can check the decision: programs automatically, and documents, archives or scripts only if you agree to that specific file. You can switch it off.
Give Windows a gatekeeper. Nothing runs on your machine without proving itself first.
