Jotti's malware scan is a free online scan service, utilizing various anti-virus programs to diagnose single files.

Found this website recently and it allows you to upload a single file and have it tested against multiply virus scan programs. If you download a sketchy file and you want have a bit more confidence in if it is clean or not, this is an excellent resource.

Note! Never trust any antivirus 100%. If the file seems sketchy, don't download it, or atleast run it in a sandboxed environment.
