Score breakdown
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.
Analysis Summary

Intelligence
The URL sits on pyrenta.z13.web.core.windows.net, a subdomain of Microsoft's legitimate Azure hosting service. Our research found two separate reports explicitly naming web.core.windows.net subdomains as vehicles for tech-support scams that display fake virus warnings and direct users to paid call centers. The page itself returned a server error during capture, which is consistent with disposable scam pages that appear and disappear quickly. No legitimate business named Pyrenta is registered to this subdomain, and the hosting IP shows zero abuse history only because the abuse occurs at the subdomain level rather than the IP. The combination of platform abuse reports, lack of any business registration, and the known scam pattern on this exact hosting service outweighs the clean browser blocklist result.
Web Research Findings
Our live research agent queries scam-report databases, consumer-review sites, news coverage, and general web search for pyrenta.z13.web.core.windows.net, then cross-checks business-registration records and look-alike domain patterns. Everything below is pulled from what it actually found.
- The domain 'pyrenta.z13.web.core.windows.net' is a subdomain of 'web.core.windows.net', a legitimate Microsoft Azure hosting platform.
- Subdomains on 'web.core.windows.net' are frequently used by malicious actors to host tech-support scams, phishing pages, and fake virus alerts.

- Users are often redirected to these subdomains via malicious advertisements or browser hijacks while browsing other websites.
- There is no evidence of a legitimate company named 'Pyrenta' associated with this specific Azure subdomain; 'Pyrenta' appears as a generic product name for unrelated items (e.g., toothbrushes) on e-commerce sites.

"It looks like the malicious fake tech websites are at it again. Hosted by Microsoft Azure free accounts or, compromised accounts... Typically all linked to a scam call center in India"
- Microsoft Communityopen
"Seeing your browser suddenly jump to web.core.windows.net with a blaring “virus alert” is unsettling... it's a classic tech-support scam riding on Microsoft's Azure hosting."
BleepingComputer and Microsoft Community forums both document cases where attackers host fake tech-support pages on web.core.windows.net subdomains.

Safety FAQ
Common questions, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- pyrenta.z13.web.core.windows.net raises serious red flags as a scam site — avoid interacting with it. Our review tagged it for tech support scam. The domain is 31 years old through MarkMonitor Inc.. It may not be an outright scam, but the risk is high enough that you should verify it independently before trusting it with money or data.
- Proceed with caution — pyrenta.z13.web.core.windows.net scores 46/100 on our trust scale. We found enough warning signals to recommend verifying it through independent channels before entering credentials or money.
- If you've already paid or handed over details on pyrenta.z13.web.core.windows.net, act quickly. 1) Contact your bank or card issuer immediately and ask to dispute the charge or open a chargeback — the sooner you act, the better your odds. 2) Report the site to the U.S. FTC at reportfraud.ftc.gov or the FBI's IC3 at ic3.gov, and in the UK to Action Fraud at actionfraud.police.uk. 3) If you entered a password, change it on pyrenta.z13.web.core.windows.net and anywhere you reused it, and turn on two-factor authentication. 4) Watch your bank and email for follow-up fraud, and keep screenshots as evidence.
- Often yes, if you act fast. Payments made by credit or debit card can frequently be reversed through a chargeback or dispute — contact your bank right away and explain it was a fraudulent site. Bank transfers and gift-card or voucher payments are much harder to recover, but you should still report them to your bank and to the FTC (reportfraud.ftc.gov) or Action Fraud (actionfraud.police.uk). Avoid any "refund" or "recovery" service that contacts you first — it's usually a follow-up scam.
- Just viewing a scam page is usually low-risk on an up-to-date browser — the real danger is what it asks you to DO (enter details, download a file, send money). If you downloaded anything, run a full antivirus scan and treat the file as untrusted. If you entered a password or card number, change the password everywhere you reused it and contact your bank.
- You can report pyrenta.z13.web.core.windows.net through several official channels: the U.S. FTC at reportfraud.ftc.gov, the FBI's Internet Crime Complaint Center (IC3) at ic3.gov, and — in the UK — Action Fraud at actionfraud.police.uk. You can also flag it to Google Safe Browsing (safebrowsing.google.com/safebrowsing/report_phish) so other browsers warn about it, and report it to the company being impersonated if there is one. Reporting helps get scam sites taken down faster.
- Modern scams are built to look convincing. A valid SSL padlock, a polished template, stock photos, fake reviews, and a trust badge can all be added in minutes and prove nothing about who runs the site. Scammers buy cheap domains, clone real designs, and copy legal pages wholesale. That's exactly why an automated review that checks the domain's age, hosting, blacklists, and behaviour — rather than just how the page looks — is more reliable than a first impression.
- No — pyrenta.z13.web.core.windows.net is not currently on the major browser blocklist feeds that Chrome, Safari, Firefox, and Edge rely on. Note that blocklists can lag behind brand-new scam domains, so "not listed" is reassuring but not a guarantee on its own.
- pyrenta.z13.web.core.windows.net is 31 years old, registered on August 10, 1995 through MarkMonitor Inc.. A multi-year registration history is one of the stronger signals against a scam, though it's never a guarantee on its own — established domains can still be misused.
- Yes — pyrenta.z13.web.core.windows.net presents a valid TLSv1.3 certificate issued by Microsoft Corporation · Microsoft TLS G2 RSA CA OCSP 16, valid for another 111 days. Important caveat: SSL only encrypts the connection between you and the site — it does not verify who runs it. Almost all scam sites now have valid SSL too, so a padlock alone never means "safe".
- pyrenta.z13.web.core.windows.net resolves to an IP operated by Microsoft Limited in US (Data Center/Web Hosting/Transit). Hosting location alone doesn't make a site good or bad — but hosting that doesn't match a brand's claimed country, or that sits on networks known for abuse, is one of the many signals we weigh alongside the verdict above.
- This report is a record of the scan run on July 21, 2026, and the verdict reflects that point in time. Scam sites change fast — they can go live, get flagged, or vanish within days — so if you believe something about pyrenta.z13.web.core.windows.net has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
