Verifying against the live site and live WHOIS/DNS…
Common questions
Is unirio.br legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns unirio.br?
Nobody has completed AboutUs's owner verification for unirio.br. That's true of most sites here — it isn't itself a warning sign.

AboutUs has not vetted this site. Everything below is what we could measure automatically. Anything you do on the site — paying, sharing personal details, downloading — is between you and the site, not AboutUs.
Current facts
Latest available measurements; dated entries retain their dates. These are measurements, not an endorsement of the site.
We withhold an authority number until independent evidence (global rank, link-graph presence) has accrued. The facts we do have about this site are shown below — we'd rather say “not enough signals yet” than invent a low score.
Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 80 days ago); 3/3 transport and email checks available (oldest recorded about 80 days ago). This is evidence coverage, not a probability that a website is safe.
Recorded HTTPS check did not confirm a valid connection
