Hi Marilyn. It may be that they weren't actually sent by forum members.
I received an e-mail from postmaster@taiyo.de to say an e-mail (subject LaserJet printers) with an attachment containing this virus had been received from my e-mail address.
It is not one that I sent (I've never mailed anything to them nor have I sent any with LaserJet Printers as the subject)).
My system has been checked (Nortons) and is virus free. So this virus is obviously using false addresses and headers.
As a precaution any e-mail's I send to forum members with an attachment, will include in the subject line the word 'Technics'. That way you will know it is genuine. If 'Technics' is not included in the subject line, then don't open it.
John
