File Shield
Watches Desktop, Downloads, Documents, Temp and startup folders. New or changed files are scanned the moment they arrive.
Native Windows security, without the noise
Your PC,
quietly protected.
AspisGuard pairs real-time file monitoring with a signature and behavior engine, an encrypted quarantine vault, and a deep PC cleaner — all running locally on your machine.

Protection
Everything that matters.
Nothing you don’t.
Six practical defenses, built into one compact Windows app. No dashboards full of noise, no cloud dependency, no upsell.
Known-threat matching
SHA-256 hashes and wildcard byte patterns identify known files without uploading a single byte to a server.
Behavior rules
Catches encoded PowerShell commands, macro auto-runs, ransomware recovery tampering, disguised extensions, and suspicious startup chains.
Encrypted quarantine
Threats move into a machine-bound vault using AES-256-CBC and HMAC-SHA256. Restore or destroy them when you decide.
Smart Cleaner
Reclaims temporary files, browser caches, crash dumps, old logs and update leftovers. Passwords, history, and personal files stay untouched.
Startup Guard
Review everything that launches with Windows, back up entries before disabling them, and flag suspicious Run commands.
Scanner
A scanner that tells you why.
Quick, full, or folder scans use signatures and behavior rules in a single pass. Findings are explained in plain English before you act.
- Quick, full, and custom-folder scans
- Severity, signatures, and readable reasons
- One-click quarantine, delete, or ignore
- ZIP archive inspection and scheduled quick scans

PC Cleaner
Clean the mess Windows leaves behind.
Analyze first, then clean only what you select. AspisGuard measures every category and skips files that are currently in use.
- Temporary files, caches, dumps, and old logs
- Exact sizes before anything is deleted
- Browser passwords and history are left alone
- Advanced categories are opt-in, never preselected
How it works
From download to protected
in a few minutes.
Download and launch
One executable, no installer and no account. Windows will ask for administrator rights so AspisGuard can scan protected locations.
Run your first scan
Quick scan checks the usual hiding places. Full scan checks every fixed drive. Findings can be quarantined, deleted, or ignored.
Leave File Shield on
It continues watching in real time from the tray, automatically quarantining confirmed threats while you use your PC.
Security model
Security that stays on your side of the network.
No cloud scanning. No account. No telemetry. Everything that matters stays on the PC, under your control.
Local by design
Hashes, byte patterns, behavior rules, and archive inspection all run on the machine. Files are never uploaded.
Encrypted at rest
Quarantine uses AES-256-CBC with an HMAC-SHA256 integrity check and a key protected by Windows DPAPI.

FAQ
Straight answers.
No fine print theatre. Here is how the app actually behaves.
Is AspisGuard free?
Yes. This local build is free to run. There is no account, subscription, upsell, or telemetry.
Does it replace Microsoft Defender?
No. AspisGuard is an independent scanner and does not disable Windows security. Keep Windows and Defender updated as usual.
Are my files uploaded anywhere?
No. Scanning and quarantine are local. The only network request happens if you configure a definitions update URL and click check.
Does it work offline?
Yes. The built-in engine and local rules work without a connection. Definition updates are optional.
Why does it need administrator rights?
To inspect protected system locations, remove quarantined files, read startup entries, and empty caches that require elevation.
Will it catch everything?
No antivirus does. AspisGuard combines signatures, behavior rules, and real-time monitoring. Keep Windows updated and treat unknown files with care.
Is the download signed?
This is an unsigned local build, so Windows SmartScreen may warn. The SHA-256 checksum below is published so you can verify the exact file.
How do I uninstall it?
Exit from the tray, delete the program folder, remove %ProgramData%\AspisGuard, and disable “Start with Windows” first if you enabled it.
