I built a $19 Windows guard that blocks known attacker servers — no subscription

I'm a school teacher from Narowal, Pakistan. Between classes and after midnight, I build small tools. VigilShield is one of them: a guard for Windows 10/11 that watches what your PC talks to — and blocks it when it talks to a known attacker server. Here's the problem it solves. Most attacks start with one click: ENISA's Threat Landscape 2025 found phishing was the initial intrusion method in about 60% of cyber incidents (EU data, July 2024–June 2025). J.D. Power 2025 found 29% of bank checking, savings and debit holders experienced fraud in the past 12 months. The FTC counted $12.5 billion lost to fraud in the US in 2024. One fake bank page, one password typed, and an account is drained before you notice. Your antivirus watches files. VigilShield watches the connection leaving your PC. What it does: Real-time network watch — every outbound connection is checked against a threat list from public feeds (abuse.ch, FireHOL). A match is blocked automatically in Windows Firewall, with an instant red alert and sound. One click undoes every block. Ransomware tripwires — canary files in your Documents that scream if something starts encrypting. Suspicious-program alerts — programs hiding in temp folders, double extensions, random-looking names. USB, startup and hosts guards — plus a quarantine manager that moves files aside, never deletes them. Honest limits, stated on the site itself: it cannot predict attacks before they start, it is NOT an antivirus replacement, and it does not stop 100% of attacks. It runs entirely on your PC — no data is sent anywhere. The only internet it uses is downloading the threat list when you click update. $19, one time. No subscription. 14-day no-questions refunds, free updates. https://vigilshield.pages.dev Don't wait until you're the headline.
