Sending a file to analyze anything happens the file is corrupted?

It has a file on my computer that was originally detected by ClamWin that the USA’s database clamav only that avast does not detect it.

I sent the file to virus total and the result: http://www.virustotal.com/pt/analisis/c0ffdf557293a3c14e442f37dc85ba3f35c7c100ef9025983b63592c7b29dd2c-1247715735

More if I have the original file in 19 anti virus detect it.

To see the original file is the link: http://www.virustotal.com/pt/analisis/7ae9aae77884ac0baa2f8168b3ed4de0c0c9834a42d8e5a775f47a2c66cec237-1247715505

And because if I send in only 17 zip detect?

Is the file in zip is corrupted?

I have sent the file to look at about 4 more days until today avast does not detect.

Send the sample to virus@avast.com with undetected malware in subject and mention this post in the email body.
