Why 70+ Engines Are Better Than One

No single AV catches everything

Every antivirus product has blind spots. Malware authors test their code against popular AV before releasing it. Using 70+ engines closes that gap dramatically.

Cross-vendor consensus

When multiple independent engines flag the same file, you can be very confident it is malicious. When all engines are clean, your confidence in the file increases significantly.

Real-time databases

Each engine uses continuously updated signature databases. We query all of them simultaneously so you get the most current threat intelligence in one place.

Always Scan These Files Before Opening

Email attachments

The #1 delivery method for malware. Even if it's from someone you know — their account may have been compromised.

Software downloads

Including from seemingly legitimate sites. Malware is routinely bundled with free software, media players, and browser extensions.

Files from messaging apps

WhatsApp, Telegram, and Discord are increasingly used to deliver malware disguised as images, videos, or documents.

USB drives from others

USB drives can carry malware that spreads the moment the drive is inserted. Always scan before opening any file.

Cracked or pirated software

Malware is almost universally present in cracked software. The "free" version always has a hidden cost.

Anything that triggered a browser warning

If your browser warned you about a download, take that seriously. Scan it before opening.

Frequently Asked Questions

How do I scan a file for viruses online for free?

Use SafeSearchScan's free online virus scanner. Upload the file (up to 50MB on free, 200MB on Personal, 500MB on Professional), and we immediately scan it using MalwareBazaar, HybridAnalysis, and our proprietary SafeSearchScan engine. You get a detailed threat report in under 30 seconds — no software installation needed.

Is it safe to upload files to an online virus scanner?

SafeSearchScan uses industry-standard encryption (HTTPS/TLS) for all connections. File scanning is hash-based — we compute a SHA-256 fingerprint of your file and check it against multiple threat intelligence databases. Your actual file is never uploaded or stored. Avoid scanning files containing sensitive personal data by using our File Hash Checker for fully local, private verification.

How accurate is the online virus scan?

Our scanner uses MalwareBazaar, HybridAnalysis, and our proprietary SafeSearchScan detection engine — cross-referencing multiple threat intelligence sources. If any source flags a file, we flag it as suspicious. The detection rate for known malware is high. However, brand-new, zero-day malware may not yet be in any database. Always download software only from trusted official sources as your primary defence.

What file types can I scan?

You can scan virtually any file type: executables (.exe, .msi, .dmg, .pkg), documents (.pdf, .docx, .xlsx), archives (.zip, .rar, .7z), scripts (.js, .py, .sh, .bat), APK files (Android apps), and more. The maximum file size is 50MB for free accounts, 200MB for Personal plan, and 500MB for Professional plan.

When should I scan a file before opening it?

Always scan: files downloaded from websites you don't fully trust, email attachments (especially .zip, .exe, .docx, .pdf), files shared via messaging apps (WhatsApp, Telegram), cracked or pirated software, USB drives from other people, and any file that prompted an unusual warning when downloading.
