Is file.fast safe?

Why is file.fast marked "Suspicious Website"?

Gridinsoft's current assessment of file.fast is based on automated caution checks and heuristic signals associated with scam. Context considered alongside those findings includes a short domain history (10 months old) and limited public traffic history. The listed status means the domain currently appears in Gridinsoft's own Threat List; it is not a consensus of external providers. 5 of 25 publicly displayed security sources report a warning. A separate license-restricted partner security signal also contributes to the automated assessment; its provider name and verdict cannot be displayed publicly under the source license.
