Someone tells you your website is "dangerous" or "suspicious". Maybe it was a browser warning, an antivirus pop-up or a block page at a customer's office.
The two words sound similar, but vendors use them differently. Knowing which one you have tells you how serious it is and what to do next.
Key takeaways
- "Dangerous" usually means a confirmed malware or phishing verdict that blocks visitors.
- "Suspicious" is usually a risk score from a machine-learning or reputation system.
- Suspicious labels are often false positives on new, small or recently changed sites.
- Each vendor needs its own removal request; VirusTotal shows you which ones are involved.
Dangerous versus suspicious
Vendors typically use the labels like this:
- Dangerous / Malicious: the vendor believes your site actively harms visitors with malware or phishing. Browsers and antivirus usually block the page completely.
- Suspicious: the vendor's model sees risk signals but no confirmed threat. Some products warn, others block, especially in corporate networks.
- Unrated / Newly registered: no verdict yet. Strict firewalls may still block unknown sites.
Find out who flagged you
Scan your domain on VirusTotal and note every vendor and label. Our link checker guide explains how to read the results. Also check Google Search Console for Security Issues and ask the person who reported the warning for a screenshot, since the block page names the product.
Why clean sites are labelled suspicious
In our cases, suspicious labels are mostly triggered by:
- A new domain or a recent change of hosting, owner or DNS.
- Hosting on an IP range shared with abusive sites.
- Login or payment forms that resemble phishing templates.
- Heavy redirects, URL shorteners or obfuscated scripts.
- Missing company information, privacy policy or contact details.
Machine-learning vendors such as alphaMountain.ai and CRDF are frequent sources of suspicious labels on VirusTotal.
How to fix a dangerous label
Treat a dangerous label as a possible compromise until proven otherwise. Check for injected code, unknown admin users and modified files, clean up, then request a review from each vendor. See how to check if WordPress is hacked and our blacklist removal checklist.
How to fix a suspicious label
Strengthen trust signals first: add clear company and contact details, keep SSL valid, reduce redirects and third-party scripts. Then submit a false positive or reclassification request to each vendor, using our false positive reporting template.
Frequently asked questions
Is "suspicious" less urgent than "dangerous"?
Usually, but suspicious labels spread to other vendors and firewalls, so fix them early.
Can I remove the label myself?
Yes, every vendor has a public process. The work is in finding all vendors and providing the right evidence.
Why does the label only appear for some visitors?
Visitors use different browsers, antivirus products and networks. Only those using an affected vendor see the warning.
Will the label disappear by itself?
Sometimes, after weeks or months. A removal request is much faster.
