Skip to main content AI Studio  add-on for Spider.

A living spider’s web drawn across the page. Threats — malware, phishing, trackers, smart-TV spyware — fly toward the center and are caught in the silk before they arrive. Safe traffic passes through untouched and reaches entry 0000 in Shield’s ledger: you — every app, every screen — protected at the center of the web.

Spider Shield · Free antivirus

Nothing gets to you.

Spider maps the whole web for a living. Shield is what we spin from it — a web across your device that catches malware, spyware, phishing, and the trackers inside your TV before a single byte lands. Safe traffic passes. Threats stick. It never costs a thing.

01 — Doctrine

Old antivirus chases. A web doesn’t chase — it catches.

Traditional antivirus waits for a malicious file to land, then hunts it across your disk. Shield is strung one layer earlier — across the network, where threats already fly. Malware, spyware, phishing pages, tracking payloads: caught in the silk before a single byte arrives. Nothing lands, so there’s nothing to clean.

02 — Scope

Every app. Every screen. Even the TV.

Shield filters at the device, below the browser — Mail, games, and whatever installs next are already covered. And the living room is on the list: smart TVs ship with programs that watch what you watch and report it to data brokers. Shield names that entire spy stack, endpoint by endpoint, and starves it. On Android TV, the web is strung on the television itself — Shield installs there directly.

03 — Silk

The silk is spun from the crawl.

Spider crawls and maps the web at a scale few companies match — that’s the day job. Shield is what we spin from it: threat lists that name the ad networks, spyware brokers, phishing kits, and malware droppers across the internet — cryptographically signed, refreshed every hour, cached so protection holds offline. When a new campaign stands up, the web is already re-strung. You don’t have to do anything.

04 — Vigilance

Sometimes the road itself lies.

A hijacked router can hand you a counterfeit page at a real address — you type the URL you trust and land on a donation scam styled to the pixel. Shield doesn’t take the network’s word for it: your device answers its own DNS against signed intelligence, and a small amount of operational data is collected to keep testing that trusted routes still lead where they should. That’s the data we take — and protecting you is the reason.

Disclosed in the Terms · collected to defend the route, not to profile you

05 — Price

Free is the price.

No trial, no tier, no upsell. The engine is the product.

06 — Trust

Shield watches the road, never you.

  • Verdicts on your device

    Blocking decisions are made locally, against Shield’s filter lists of real ad, tracker, spyware, malware, and phishing domains. Your browsing is never sent away to be scored.

    On-device
  • Signed threat intelligence

    Threat lists are cryptographically signed and verified on your device before they’re trusted — refreshed hourly, cached so protection holds when you’re offline.

  • Data collected in your defense

    A hijacked router can forge where a trusted address leads. Shield collects a small amount of operational data to keep testing those routes — that’s the collection, and the Terms describe it plainly.

    Vigilance
  • Fails open, never dark

    If a filter list ever misfires, Shield lets traffic through rather than taking your internet down. Protection should never hold your connection hostage.

    Fail-safe
  • No account, ever

    No sign-up, no email, no login. Install is the whole relationship.

07 — Questions

Before you trust a spider.

Is Spider Shield really an antivirus?

Yes — antivirus one layer earlier. Traditional antivirus waits for a malicious file to land, then scans for it. Shield refuses the delivery: it blocks the connections that carry malware, spyware, phishing pages, and tracking payloads before a single byte arrives. Nothing lands, so there’s nothing to clean.

What makes Spider Shield the best free antivirus?

Three things. It blocks threats before they arrive instead of scanning after. Its threat lists name the whole net of bad actors — ad networks, spyware brokers, phishing kits, malware droppers, and smart-TV trackers — and are cryptographically signed and refreshed hourly. And it’s 100% free: no trial, no tier, no upsell.

Is Spider Shield really 100% free?

Yes — no trial, no tier, no upsell. Shield is sustained by the bandwidth-sharing described in the Terms, disclosed before you download. The protection itself never costs anything.

Can Spider Shield protect my smart TV?

Smart TVs ship with programs that watch what you watch — automatic content recognition (ACR) that fingerprints what’s on screen and reports it to data brokers. Shield’s filter lists name that entire reporting ecosystem, from Samsung ACR to Samba, Inscape, Alphonso, and Roku telemetry. On Android TV, install Shield on the television itself — the free Android app runs there directly. For every other TV, pointing its DNS at a machine running Shield starves its calls home the same way.

Why does Shield collect some data?

Because sometimes the network itself is the attacker. A hijacked router can serve a counterfeit page at a real address — you type a URL you trust and land on a scam styled to the pixel. Shield answers DNS on your device instead of trusting the router, and it collects a small amount of operational data to keep verifying that well-known routes lead where they should. That’s the data we take, protecting you is the reason we take it, and the Terms describe it plainly.

Does Spider Shield collect or sell my browsing history?

Blocking verdicts are made on your device against Shield’s filter lists — your browsing isn’t sent to a server to be scored. The only collection is the small operational data used to detect route hijacking, disclosed up front. The Terms are the authoritative description of what the software does and doesn’t do.

Will it slow down my computer?

Shield removes traffic rather than adding it. With ads, trackers, spyware beacons, and telemetry filtered out, pages make far fewer connections than they did before — and there’s no scan engine grinding your disk in the background.

Does it protect every app, or just my browser?

Every app. Shield filters at the device, below the browser — Mail, Slack, games, and whatever installs next are covered.

How is Shield different from an ad-blocker extension?

An extension protects one browser’s tabs. Shield protects the machine: the same blocking applies to every app and every network you join — home Wi-Fi, café, hotel, airport, office.

Do I need an account or any setup?

No. There’s no sign-up and nothing to configure — install it, and protection is on.

Which platforms does Spider Shield run on?

macOS, Windows, Linux — and Android, covering phones, tablets, and Android TV. One free download for each.

Nothing to clean. It never got in.
