Dual Engine — two scanners. One goal.

Dual Engine

See more. Stop more.

Antivirus AI combines two independent engines into one powerful team—for maximum detection.

Engine 1: Protectstar AI Engine

Our own engine is the core: signatures, heuristics, AI Life Rules, and the AI Cloud work together to catch new and unknown threats early.
Awarded the BIG Innovation Award 2025 and the AI Excellence Award 2025.
Independently verified by AV‑TEST with 99.8% real‑time detection and 99.9% for widespread malware.

Engine 2: Dr.Web Engine

An industry‑grade secondary scanner with broad, global signature expertise.
It provides a second opinion, cross‑checks results, and reduces blind spots—especially where pure heuristics reach their limits.

How both work together

Parallel analyses, intelligent reconciliation, conflict resolution.
If one engine hesitates, the other double‑checks.
This lowers false positives and reduces the risk of anything slipping through—while keeping resource use minimal.
And, of course, privacy‑first from day one: No trackers. No ad IDs.

Tested & awarded

  • AV‑TEST certification — Antivirus AI: 99.8% (real‑time), 99.9% (widespread malware).

  • App Defense Alliance / DEKRA — MASA L1 (03/2025) — Verified against OWASP MASVS L1 (secure app architecture & data transmission).

  • Awards 2025 — BIG Innovation Award (Antivirus AI), AI Excellence Award (Antivirus AI).

  • Testing Ground Labs — independently tested; results confirm high detection performance.

Why two engines?

  • Higher hit rate — two perspectives on every file.

  • Fewer blind spots — strengths add up, weaknesses are covered.

  • Fast response — instant updates, real‑time AI rules.

  • Simple in practice — switch on, stay protected.
