I have been using Virus Total and I am fully satisfied by this product and features that Virus Total is offering.

-You can check if the files that you downloaded from internet are safe -It uses a lot of antivirus to check the file -Also check the hash of the file and if someone already uploaded it it gets you the result instantly

VirusTotal does a single, crucial job: analyze any file, URL, domain, or IP address for malware threats. This is one of those great tools that should really be used both at work and in everyday life. If you're concerned about the potential for malware from any of the aforementioned sources, don't just "wing it", send it to VirusTotal! If Virus Total can't automatically tell if there's an issue, the questionable source will be sent to security experts for further analysis. Sounds good to me! You can also vote and comment, on sites for example, providing information to others. Using VT Graph on any site will allow you to go deeper, finding connected IP address, domains, sites, and subdomains, allowing you to do a little online investigating.
