    So nothing to worry about. Files scan clean with onboard AV and secondary Anti-Malware programs.

    Below is from their support area.



    1) A list of each reviewing partner and their findings. Possible findings are:


    • Undetected: The given engine does not detect the file as malicious.
    • Suspicious: The given engine flags the file as suspicious.
    • Unable to process file type: The given engine does not understand the type of file submitted and so will not produce verdicts for it.
    • Timeout: The given engine reached VirusTotal's time execution limit when processing the file and so no verdicts were recorded for it.

    Make of that what you will.

    Take a look at this PDF:

    Search it for the word "detected". I got 21 hits, some related to Virustotal.
