why can't you block AnyTech365.com....they are a scam company posing as Microsoft supported, stealing information?

AnyTech365 and similar “support” outfits match the pattern of tech support scams described in Microsoft guidance: they present themselves as official or Microsoft‑approved support, try to scare users about infections or “dark web leaks,” and then push for remote access and payment. Microsoft cannot globally “block” a specific company on all Windows devices, but Windows and Microsoft services provide protections and clear rules for how to handle this situation.

Key points relevant to this case:

1. Microsoft does not use companies like this to cold‑call or pop up on screens
   • Microsoft does not send unsolicited emails or make unsolicited phone calls to request personal or financial information or to fix a computer.
   • Any communication with Microsoft support must be initiated by the user through official channels.
   • Error or warning messages from Microsoft never include a phone number to call.
2. The behavior described matches a tech support scam
   • Scammers commonly:
     • Claim to be “Microsoft support” or “Microsoft partner support.”
     • Tell users their data is on the dark web or that all devices are infected.
     • Demand remote access tools be installed.
   • Microsoft documentation explicitly calls out these tactics as tech support scams.
3. What to do now
   • Do not grant AnyTech365 (or any similar service) remote access to the device.
   • Do not provide payment, credit card, banking, or other sensitive personal information.
   • If any remote access or software installation was already allowed (even briefly):
     1. Uninstall any applications that were installed at their request.
     2. Run a full scan with Microsoft Defender Antivirus and apply all security updates.
     3. Change passwords for important accounts (email, banking, Microsoft account).
     4. Monitor accounts and sign‑in activity for anything unusual.
   • If any money was paid, contact the bank or card issuer and explain that it may have been a tech support scam.
4. How Microsoft protects and why it can’t just “block” one company
   • Windows, Microsoft Edge, and Microsoft Defender use technologies like Microsoft Defender SmartScreen to block known malicious or scam sites, but scammers constantly change domains, phone numbers, and infrastructure.
   • Microsoft publishes general protections and detection guidance (for example, enabling Microsoft Defender Antivirus, using Edge with SmartScreen, and avoiding third‑party download sites) instead of hard‑coding individual company names.
   • Users and organizations are encouraged to report scam sites and numbers so they can be added to blocklists and used for law‑enforcement and ecosystem protection.
5. How to protect against these scams going forward
   • Use Microsoft Edge when browsing; it blocks many known support‑scam sites using Microsoft Defender SmartScreen and can stop pop‑up dialog loops.
   • Download software only from official vendor sites or the Microsoft Store; avoid third‑party download sites that may bundle scamware or unwanted software.
   • If a pop‑up or email claims to be from Microsoft and includes a phone number, treat it as a scam.
   • If the browser is “locked” by a scary pop‑up, close it with Alt+F4 or use Ctrl+Alt+Del → Task Manager to end the browser process, then restart the PC.
6. How to report this
   • Report the incident to Microsoft at www.microsoft.com/reportascam so the information can be used to improve protections and share intelligence about scam operations.
   • Suspicious or unsafe websites can also be reported using Microsoft’s Report an unsafe site form.

The refusal to grant remote access was the correct action. Following the steps above and reporting the scam will help protect both this device and other users.
