To do this, you need to specify the download link of a file. That is the direct download link of a file, not just the download page address. For example, if you want to scan an .exe file, you will need to link directly to the .exe file. If you want to scan a .doc file, you will need to link directly to the .doc file. You can see this by hovering over the link and viewing the address in your browser.

Next, go to VirusTotal.com page in your web browser. This tool has been owned by Google since 2012.

Click the "URL" tab on the page and then paste the link you copied into the box. Click the search button or press Enter to scan the file.

VirusTotal will download the file you specified to the servers and scan it with a large number of different antivirus tools. If others have recently scanned this file, VirusTotal will show you recent scan results.

If you see 'No engines detected this URL' , it means there is no VirusTotal antivirus tool that detects a problem file.

"0/65" means that 0 out of 65 VirusTotal antivirus tools found malware on this file. This means the file you want to download is clean and safe. Of course, there may be new and strange malware that these antivirus programs can't detect, so you should be careful and only download software from sources you trust.

  1. Free software download sites are safe

In some cases, nearly all tools find viruses. In other cases, only a few anti-virus tools will detect the problem. This may be that some antivirus tools have discovered new malware before other tools. You can scroll down to see which anti-virus tools detect the virus in the file, see more details about the file and community comments about whether the URL is safe. (For example, in some cases, it may be flagged for crapware software and is often easily overlooked.)

Integrate VirusTotal into your web browser

They will integrate VirusTotal into your browser, allowing you to right-click on a link on any site and select an 'Scan with VirusTotal' option . You will not have to visit the VirusTotal website and copy and paste links.

Extensions are available for Google Chrome, Mozilla Firefox and Internet Explorer. Download the appropriate extension and you can right-click on a link, select the VirusTotal option to quickly scan and view the results.

If VirusTotal agrees that this is a dangerous file, you should stay away from it. If the results show there are some malware detection programs, you should be careful, but can check the detailed results of the tools to see why it thinks the files are danger.

If a file is clean and safe, it means that it does not detect any malware by antivirus tools. However, that does not mean that the file is absolutely secure, of course the antivirus software is not perfect and does not detect new malware, thus ensuring you download programs from a trusted source. .
