- Not requiredInstall and use
View protection settings, update information and recent scan records together. Optional notices help you keep track of changes and when to check.
You are purchasing an organized view of information and tools that help you check it. Microsoft Defender is built into Windows and is available without buying Y-Security.
Included features
- See protection and connection information together
View Defender status, virus definition update times, firewall settings and network information. Refresh them together with one button.
- Check previous scan times and records
View the latest quick and full scan times reported by Windows, along with records of scans starting, completing or stopping.
- Check protection status about every five minutes
When enabled, this reads protection status while the app is running. It does not automatically scan for viruses.
- Get notices about changes and overdue scans
Get notices about protection changes, failed or restored information retrieval, and new scan records. A reminder appears when the retrieved last scan time is more than seven days old. Windows notifications are optional.
- Local history, tray mode, Japanese and English
View information retrieval and change history on your PC. Choose tray mode and your display language. Regular check and notification settings are saved too.
- Help with Microsoft Defender controls
Select and confirm a file or folder to call Microsoft Defender on this PC. Defender performs the scan.
Y-Security has no antivirus engine of its own or its own automatic removal, quarantine or repair functions. It cannot start a quick or full scan from within the app.
Regular checks read status information. They do not run scans every five minutes, and the seven-day scan reminder does not start a scan.
A completed scan does not establish complete safety or successful malware removal. Whether Windows notifications appear also depends on your Windows settings.

License scope and replacing a PC
Use Y-Security on up to 5 PCs belonging to you and your household. This is a license limit; the app does not register devices or technically enforce the PC count. Distribution or resale of the installer beyond the licensed scope is not allowed.
To replace a PC, stop using the app on the old PC or uninstall it, then install it on a compatible new PC. No application to us, device release or additional transfer fee is required, provided no more than 5 PCs are in use.
The license to use the purchased version has no expiry. No activation or periodic license verification is required. Use it on up to 5 PCs within the supported environment. Compatibility with future Windows versions, updates, support and redownload availability are governed by the terms accepted at purchase.
Preparing for sale: download, install and use
The sale version is downloaded after payment is confirmed, then installed and used. No activation code, device registration or periodic license verification is required. The release will be checked on Windows before delivery.
The software and Microsoft Defender run on your own PC. The server handles orders and downloads. Windows and Defender updates, downloads and online support require an internet connection.
Planned sales and support terms — draft
Sales are not open yet. The following outlines the proposed terms, not an announcement that sales have begun. We will confirm seller information, system requirements, payment and download delivery, and publish the formal terms on the purchase and final confirmation screens before accepting orders. The terms applying to each order will be retained. Earlier orders remain subject to the terms accepted at purchase.
Cancellations & refunds
Under the proposed terms, when the product and delivery conform to the contract, cancellations or refunds for personal reasons will not be accepted. There will be no voluntary refund guarantee for changing your mind or no longer needing the product.
Non-delivery, incorrect or system-generated duplicate charges, non-conformity with the contract, and cancellation, termination, price reduction or refund rights recognised by law will be handled according to the facts and applicable law. Completing a download alone does not restrict those rights.
Redownloads are stopped as appropriate to the order status after a refund or cancellation. Downloaded software is not remotely disabled. Usage rights after a refund are governed by the individual agreement and the terms accepted at purchase.
Reinstallation and permitted use
Use Y-Security on up to 5 PCs belonging to you and your household. This is a license limit; the app does not register devices or technically enforce the PC count. Distribution or resale of the installer beyond the licensed scope is not allowed.
Use your saved installer to reinstall. No device registration, removal or reactivation is required. Keep a copy of the installer and your order information. Redownload availability is governed by the terms accepted at purchase.
The license to use the purchased version has no expiry. No activation or periodic license verification is required. Use it on up to 5 PCs within the supported environment. Compatibility with future Windows versions, updates, support and redownload availability are governed by the terms accepted at purchase.
Email support
Enquiries about this product’s orders, downloads and provided features are accepted at y.security2026@gmail.com. The purchase does not include personal training for a fixed term or for life, immediate service, guaranteed response times, telephone technical guidance, visits, remote control, PC repairs, or a guarantee to resolve every problem. Contractual and statutory obligations will still be fulfilled. An automatic acknowledgement confirms receipt, not resolution or refund approval.
Versions and updates
The one-time purchase covers the license to use the version recorded in your order. Future major upgrades, compatibility with all future Windows versions, unlimited redownloads and indefinite individual guidance are not planned as part of the purchase. Ending updates or routine support does not by itself end the purchased usage rights or contractual and statutory responsibilities.
The sale version is designed to start without our server. Closing the website or download service alone will not prevent a saved, compatible version from starting. This does not guarantee compatibility with future Windows versions or indefinite downloads, updates or support. Contractual and statutory obligations for existing orders will still be handled if services end.

BEFORE YOU BUY
Questions about purchasing
Are there monthly fees or automatic renewals?
Y-Security costs ¥9,980 including tax, paid once, for up to 5 PCs belonging to you and your household. There is no automatic renewal or recurring charge. See the terms accepted at purchase for permitted use, updates, support and refunds.
Which computers can I use it on?
For personal use on Windows 11. You can switch the app between Japanese and English. macOS, Android and iOS are not supported.
How does Y-Security work with Microsoft Defender?
After you select and confirm a file or folder, the app calls Microsoft Defender on this PC and displays the execution result. Y-Security has no scanning engine of its own or its own automatic removal, quarantine or repair functions. A completed scan does not establish complete safety or successful malware removal.
You can view Windows quick and full scan times and records, but cannot start these scans from within the app.
Do regular checks or notifications start automatic scans?
No. When regular checks are enabled, the app reads protection status about every five minutes while running. The reminder that more than seven days have passed since a scan is a prompt to check. Notifications do not automatically start a scan.
Can I receive notifications after closing the app window?
If tray mode and regular checks are enabled, checks continue after you close the window. They stop when you fully exit the app. Windows notifications are optional, and whether they appear also depends on your Windows settings.
What if I have paid but cannot download?
Choose “Check payment status again” on your order page. If payment still cannot be verified, contact support with your order number before placing another order.
Will a support person reply immediately?
FAQ answers are available immediately. Email y.security2026@gmail.com with enquiries about orders, downloads or features provided with your purchase. If you submit an enquiry on the website, also check the original conversation. Human support reviews enquiries in turn; it does not provide live chat or a guaranteed response time.
What are the cancellation and refund terms?
Sales are being prepared. No voluntary change-of-mind refund guarantee is planned when the product and delivery conform to the contract. Non-delivery, incorrect charges, contractual non-conformity and rights recognised by law are handled separately. See “Planned sales and support terms — draft” above. Formal terms will be published before sales open; after purchase, the terms accepted for that order can be reviewed on the order page.
Review “Cancellation and refunds” in the sales terms. After purchasing, the terms that applied to your order are saved on the order page. Include your order number when contacting support about a refund.
