Five layers, one clear report.

Each layer answers a different question about the same file, and the verdict comes from combining them.

  1. 01

    SHA-256 hash

    Compares each file's fingerprint with the local base and the lists you import: .txt with one hash per line, .csv from MalwareBazaar or .json.

  2. 02

    Content patterns

    Looks for patterns of 16 to 256 bytes, up to 5,000 per base. On import it rejects short patterns, bare MZ/PE headers and trivial repetition, which cuts false positives.

  3. 03

    YARA rules optional

    Uses your rules or those from open sources. If a rule takes too long, the program warns you and never marks the file as "clean".

  4. 04

    Static heuristics

    Looks at entropy, executables with swapped extensions, packer sections and double extensions. It only marks suspicious from a combination of signals, which avoids false alarms.

  5. 05

    Reversible quarantine

    The isolated file becomes <id>.qbr, with a manifest and SHA-256 check on restore. It never isolates anything in %SystemRoot%, Program Files or WinSxS.

It never runs the sample. The scan only reads files, in blocks, and does not follow links or folder junctions.

What it does with the result.

A scan is useless if the result isn't readable or automatable. Both paths exist.

  • Report on screen, in HTML or in JSON

    Result in the terminal for a quick read; --report-html to read at your leisure and --report-json to plug into another program.

  • An exit code that tells the truth

    Clean, found something or incomplete scan: each result has its own code, ideal for automation.

  • Window in Portuguese, English and Spanish

    The interface follows the system language. The scan result and the report come out in Portuguese.

  • Your call on what is suspicious

    You decide: a suspicious file only goes to quarantine if you ask (--quarantine-suspicious). The default is to show and wait.

How it reaches your computer.
