Viruses coming from Chaossw.com

[DaForce]

Hi Guys,

Just receieved this email reporting to be coming from some fake address at chaosgroup.com. But after closer inspection it looks as if the email is actually coming from ns.chaossw.com as the IP traces back to that address.
It looks like someone on that network either has a virus or your mail server isnt as secure as it should be
Can this be looked into.

Also the attachment was details05_daforce.txt.pif

Thanks

Ahh ok. So someone on the chaossw network has netsky...hahha kinda funny, but unfortunate at the same time.
