suspicious file undetected by avast but detected at virus total as Sinowal.BI

I’ve found this file in my PC, C:\system.exe; it is not detected by avast but is detected by different anti virus at Virustotal.com as a Sinowal.BI variant…

May I post it here, or anywhere else?

Thanks

Can you send the samples to virus@avast.com ?
You can zip and password the files… Inform a link to this thread and the password used.
You can send the files to Chest and, from there, resend to Alwil for analysis.
Thanks.

I’ve sent the zipped file to virus@avast.com.

The password used is pass2448

Thanks for your help

did you include the password in the body of the file or a link to this thread
if this is not the case then it might be worth re-sending it with “virus” as this is the usual reccomended password

OK, file sent again with the suggested password…
