SEOTechTests methodology: Data source: a live VirusTotal API query aggregating dozens of antivirus/security-vendor verdicts for this domain. FAIL when multiple vendors flag it malicious; PASS when none do; UNKNOWN when VirusTotal isn't configured, times out, or errors -- never presented as a clean result.
Standards and vendor-documented behavior can change. This reflects the source as last reviewed above, not a permanent guarantee.
FAQ
What does the VirusTotal Domain Checker test?
It queries VirusTotal's aggregated verdicts from dozens of independent antivirus and security-vendor engines for this domain, and reports how many currently flag it as malicious or suspicious.
Why does SEOTechTests use VirusTotal?
VirusTotal aggregates many independent vendor engines behind one API, so a single query gives multi-vendor coverage rather than relying on one company's opinion.
Does a clean VirusTotal result mean a domain is completely safe?
No. It means no participating vendor currently flags the domain -- vendor detection can lag a very recent compromise, and VirusTotal's engines don't claim to catch every threat.
Why can VirusTotal return UNKNOWN?
VirusTotal requires an API key. If it isn't configured in this environment, or the request times out or the account hits a rate limit, the result is UNKNOWN, never a false PASS.
