AI product readWeb safety protection browser extension that works as a companion to the Kingsoft Duba (金山毒霸) Windows desktop antivirus, checking URLs and page content against a cloud-based threat database to block phishing, fraud, and malware sites.
Protects Chrome/Edge users from visiting phishing, fraud, and trojan-hosting websites by leveraging Kingsoft's cloud-based malicious URL database. Bridges the gap between desktop antivirus and browser-level web protection.
Extension monitors all tab URLs via chrome.tabs listeners → sends URLs to the local Kingsoft Duba native app via Native Messaging → native app checks against cloud-based malicious URL database → if a threat is detected, the native app instructs the extension to navigate the tab to a block/warning page → for loaded pages, content (title, keywords, description, body text) is extracted and sent for additional analysis.

- Target users
- Windows users who have Kingsoft Duba (金山毒霸) antivirus installed / Chinese-speaking users who browse the web and want protection from phishing/fraud sites
- The extension requires the Kingsoft Duba (金山毒霸) Windows desktop client to be installed and running — without it, the native messaging connection fails and the extension is non-functional. This is noted in the store description but cannot be fully verified from source alone.
- The actual threat detection logic lives in the native desktop app, not in the extension source code. The extension is purely a bridge/connector.
- The companion desktop app may have its own paid tiers, but the extension itself contains no payment logic.
MonetizationNo paid features detected
No payment-related code, no subscription checks, no premium feature gating, no billing APIs found anywhere in the source. The 'pro' keyword matches are false positives (substring of 'Protect' in Setting_BorderProtect and base64 content in verified_contents.json). The zh_CN locale message '免费提升敢赔金额' explicitly mentions free features. The companion desktop app (金山毒霸) may have paid tiers, but the extension itself implements no payment logic.

- Reason
- The extension has no login UI, no authentication flow, no credential storage, and no account-related code. It connects to a local native host application (com.kingsoft.duba.kschext) via Chrome's Native Messaging API for all functionality. No web service login is needed for the core workflow.
