Protection 
Shows file-based threats that were identified by the file reputation service.

with that SHA-256, click a SHA-256 in the table. 
Clicking the link at the bottom of Malware Threat File Details report page 
displays all instances of the file in Web Tracking that were encountered 
within the maximum available time range, regardless of the time range

verdicts are not reflected in the Advanced Malware Protection report.

If one of the extracted files from a compressed or an archive file is 
malicious, only SHA value of the compressed or archive file is 
included in the Advanced Malware Protection report.

analysis, only SHA values of these extracted files are included in the 
File Analysis report.

that included this SHA-256 within the maximum available time range, 
regardless of the time range selected for the report.
