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.
