Unfortunately, I have recieved two of this variant also. I am using Norton's 2002 however, with the most current update downloaded. I have had no problems as I scan EVERY EMAIL coming into my system, and also SCANN EVERY EMAIL LEAVING my system also to prevent this from happening.
I used Netscape Mail for years just to combat this problem, and am forced now to use one of the MicroSoft mail programs as my cable provider will not support Netscape. Having weathered a couple of these attacks has relieved the worry I had associated with this phenomenon of Email Worms taking over the address book and mailing itself.
I am not sure my virus mailings came from anyone in AH, but I save the source information associated with these files, and some I have recieved in the past have origionated from iplanet. The best my limited network detective skills can come up with is that iplanet is a server I am routed through to get to AH. I was wondering for awhile, (and still am) if anyone was able to get my email address through association with the game. I guess it is possible since I have never made any secret of my email address.
Anyway, to wrap this up, I too have recieved virus emails from people I do not know, saying that the attachment will fix the very virus it actually is. My variant has also been W32.Klez.gen@mm.
I have it under control, and my system is clean after scanning this AM and finding nothing.
I hope all of you have faired as well as I. My lesson from all this; SCANN EVERY EMAIL COMING IN AND GOING OUT!
