I often use VirusTotal.com to checkout files I download.
There are two methods of entry, one is by entering the URL of an exe, and the other is to upload the file you would have downloaded yourself.
If I enter:
I get 0/66 on VirusTotal
If I upload the same file I get 6/66.
Just be warned, scammers and those pedalling viruses in their software can fudge the results, presumably from knowing the IP addresses used by VirusTotal.
