Here is an application called VT Hash Check that enable you quickly check the MD5 checksum of a given file against the checksum database of VirusTotal.com.

The application adds a context menu item to windows explore. Just right click any application and select ‘Check File Hash to send the checksum of that file to http://www.virustotal.com. If the checksum matches a file already scanned by VirusTotal.com then the results of 0/42 anti-virus scanners are shown.
