Searching with VirusTotal
VirusTotal stores all the analyses it performs, this allows users to search for reports given an MD5, SHA1, SHA256 or URL. Search responses return the latest scan performed on the resource of interest. VirusTotal also allows you to search through the comments that users post on files and URLs, inspect our passive DNS data and retrieve threat intelligence details regarding domains and IP addresses.

Sending files as email attachments
VirusTotal's email interface lets users send files via email and receive the scan results in their mailbox. The files are uploaded as email attachments and the results can be received either as plain text or XML. The files sent via email have a lower priority, therefore, the scan results will not always be sent back immediately. Learn more about VirusTotal's email interface.
The VirusTotal API lets you upload and scan files, submit and scan URLs, access finished scan reports and make automatic comments on URLs and files without the need of using the HTML website interface. In other words, it allows you to build simple scripts to access the information generated by VirusTotal. Its public version is limited to at most 4 requests of any nature in a given 1 minute time frame. Go ahead and read the VirusTotal Public API documentation.

Fighting malware requires close collaboration.

Keeping this in mind, we have created VirusTotal Community, a space where the antivirus industry and malware researcher can meet end-users in an effort to make internet a safer place. VirusTotal Community allows you to rate and place comments on files and web sites. Comments can be of any nature: disinfection instructions, in-the-wild locations, reverse engineering reports, etc. Learn how to register and interact with other users in VirusTotal Community.
