Malware undetected by many majopr AV's

Got today multiple times an email with an attachment.
The email text is:

"We are contacting you in regards to an unusual activity that was identified in your mailbox. As a result, your mailbox has been deactivated. To restore your mailbox, you are required to extract and run the attached mailbox utility."

Extracting the zip reveals an "utility.exe"

I sent it to VT, and most major or well known AV did not detect it, this includes avg, nod32, bitdefender, mse, f-prot, mcafee, panda, pctools and many more.

 

avast! flagged it as INFECTED and stopped it from downloading when MailWasherPro was checking for email messages...

Event Type: Warning

Sign of "Win32:Trojan-gen" has been found in "Incoming email 'your mailbox has been deactivated' From: "alert@_________" <alert@________>, To: <onecal5@________>\utility.zip#621716327\utility.exe" file.

 

Thanks, I did...

 

After submitting it to the AV companies, MSE detect it now, guess other do to. Problem solved (for now)
