What is an Online File Virus Scanner?

An online file virus scanner lets you upload a file and check it against multiple antivirus databases without installing any software. ShieldScan submits your file to VirusTotal's network of 95+ antivirus engines simultaneously — giving you a comprehensive verdict on whether the file is safe, and exactly which engines flagged it and why.

When Should You Scan a File Before Opening It?

You should scan any file you download from the internet before opening it, especially: executable files (.exe, .dll, .apk), email attachments (PDF, Word, Excel), files from unknown sources or file-sharing sites, and compressed archives (ZIP, RAR) containing unknown files. One infected file can compromise your entire system.

How to Check if a Downloaded File is Safe

Before running or opening a downloaded file, upload it to ShieldScan's file scanner. ShieldScan checks it against 95+ antivirus engines and returns results in seconds. If any engine flags the file as malicious, you'll see exactly which ones and what type of threat was detected — so you can make an informed decision before opening it.

Scan PDFs and Office Documents for Malware

PDF files and Microsoft Office documents (Word, Excel, PowerPoint) are common vectors for malware attacks. Attackers embed malicious macros, JavaScript exploits, and shellcode inside seemingly innocent documents. ShieldScan's file scanner checks all document types against 95+ antivirus engines, catching embedded threats before you open the file.
