Frequently Asked Questions
Yes, our service is completely free to use. There are no hidden costs, no subscriptions required, and no registration needed.
Files are scanned by the public VirusTotal engine. Do not upload highly sensitive or confidential documents. For more privacy, you can check the file's hash on the VirusTotal website directly without uploading the contents.
You can scan almost any file type: executables (.exe, .dll), documents (.doc, .pdf, .xls), archives (.zip, .rar), and more.
If multiple reputable engines flag the file, you should immediately delete it from your system and run a full scan with your locally installed antivirus software.
Most file scans complete within 10 to 30 seconds, depending on file size and the number of antivirus engines checking it. The report is generated as soon as all engines finish their analysis.
No installation is required. Our online virus scanner runs entirely in your web browser, so you can scan files on Windows, macOS, Linux, iOS, or Android without installing anything.
The current maximum upload size is 650 MB per file. For larger files, we recommend splitting them or using a desktop antivirus solution.
Scan results are tied to a temporary scan ID and are auto-deleted after a short period. Files submitted for scanning are processed by the VirusTotal public API under their privacy policy. We do not sell or share your scan data.
A virus checker is an online tool that scans files for malware, trojans, ransomware, and other threats. Unlike installed antivirus software, a web-based virus checker runs in your browser with no installation, and checks your file against multiple antivirus engines for a verdict in seconds.
Our virus checker uploads your file and passes it to 70+ antivirus engines that inspect its signature, behavior, and known-threat database. Each engine votes, and you get a combined verdict plus a detailed report showing exactly which engines flagged the file and why.
What Is a Virus Checker and How Does It Help?
A virus checker is a tool that inspects a file and tells you whether it contains malware. Unlike antivirus software installed on your device, an online scanner handles a single file on demand, and our file checker combines the verdict of 70+ antivirus engines so you can trust the result for downloads, documents, and email attachments.
Using a free virus checker before opening a file is the fastest way to avoid ransomware, trojans, and spyware. Most threats arrive through downloads and attachments, and a file launched before it is scanned can lock your data, steal credentials, or give attackers backdoor access to your machine.
No software to install and no paid license required. Our virus checker works from any browser on Windows, macOS, Linux, iOS, and Android. Upload, wait a few seconds for the multi-engine result, then read a clear report that shows which engines flagged the file and why.
Think of a virus checker as the safety gate between an unknown file and your computer. Scan anything you downloaded, anything attached to an email, and anything you saved from a website before you click or open it.
