Protection without panic: how TotalHeal handles detections and false positives

Quarantine instead of deletion, encryption instead of exposure, and a restore path for every mistake.

Two ways to fail

Every antivirus can fail in two directions: missing something harmful, or flagging something harmless. The second failure is often treated as harmless itself. It is not — a false positive can lock a family out of a tax file, a thesis or a business’s accounting software.

Quarantine, never silent deletion

When TotalHeal detects a threat it moves the file into quarantine. Quarantined files are encrypted on the device (ChaCha20-Poly1305) so they cannot run, and they can be restored. Quarantine always stays accessible — even when a trial has ended and protection is paused.

Learning from mistakes in public

In October 2026 an early desktop build quarantined some legitimate files. Desktop 0.3.8 stopped those detections, and 0.3.9 added a restore command that puts back files an older build quarantined by mistake. We publish these fixes in the changelog with the same prominence as new features.

Calm alerts

  • No inflated threat counts and no fake “your PC is infected” alarms.
  • One clear sentence about what was stopped, and the option to see details.
  • Interruptions only when a decision is really needed — a ransomware attempt, or a remote-access tool starting during a suspected scam call.
