http://www.virustotal.com/metodos.htmlI installed and used this today. Worked as advertised. Instead of just scanning a file with one or two antimalware programs, Virus Total scans with multiple programs.
VirusTotal - Free Online Virus and Malware Scan - Email/Uploader
VirusTotal Uploader
Virus Total Uploader (Windows, 80KB, MD5: e75ba68126f3839219949f9bd20e2dab) enables you to directly send files from your system using the context menu.
Once installed, just right click on the file you want scanned, select "send to" and then click on Virus Total.
