VirusTotal is a platform that brings together hundreds of antivirus and detection engines to make them available to the user so that he can perform analysis of URLs, IP addresses or domains as well as files uploaded to the same platform. This allows you to check if a link or file really contains malware, since you would not be analyzing with only one antivirus, but with dozens at a time.
How to analyze a web page in VirusTotal?
The operation is simple, you access the website, go to the “URL” section, paste the URL you want to analyze and wait for the hundreds of antivirus and detection engines to check based on signatures if the URL you sent points to a malicious resource or not, in this case, this is cleaner than a bald man’s head after shampooing.

You will see possible detections in red, while, if everything goes well, you should see it in green.
How to scan a file in VirusTotal?
To analyze files the process is almost the same, instead of going to “URL”, you go directly to “file”, select it or drag and drop it into the website, with this done, the file will be analyzed in the same way, although you should know that in this case, the sample is sent to all detection engines and antivirus, so, if you are professionally dedicated to the development of exploits, maybe the best is not to use VirusTotal but other alternatives that do not perform this last action when you send the file to be analyzed.

Can VirusTotal be installed?
