Not a big surprise: a new Netsky variant has been found. This one doesn't seem to be too widespread (we only have one report so far, from Australia). But it's nasty, as it sends messages with fake announcments from antivirus vendors claiming the attachment is scanned and declared clean - when it's not.
This variant names several antivirus vendors, including us.
Here's an example of an email sent by Netsky.O:
From: random-email-address To: recipients-email-address Subject: Re: Mail Authentification
