Availability check
The service looks at DNS, HTTP/HTTPS response, TLS and redirect chain. An unexpected transition to another domain or a certificate error is a reason to check the site more deeply.
Checking the site for viruses and malicious code
Enter the domain or full URL. Protocol optional:example.comorhttps://example.com.
What is being checked
DNS, HTTP/TLS, redirects, HTML, JavaScript, iframe and external resources. Heuristic signals are not evidence of infection.
Checking the site for viruses and malicious code
The tool helps to conduct an initial technical analysis of the site before an SEO audit, domain transfer or advertising publication. It collects signals that may indicate hacking, unwanted redirects and dangerous external connections.
Code and external resources
HTML, JavaScript, iframe and connected resources are analyzed. This helps you spot suspicious scripts, hidden inserts, and links to third-party sites.
Not an antivirus in the browser
The result shows technical signals, rather than providing a medical “diagnosis” for the site. A clean report does not eliminate the threat, and the detected signal requires manual verification.
What to do after checking
Save the result, check server logs, CMS and recent file changes. If you suspect hacking, change the access and contact a security specialist.
SEO tip:the check is especially useful if pages disappear from the index, visitors are taken to another site, or unfamiliar URLs appear in the results.
