At the abuse and support addresses we've been receiving a large number of messages that are all approximately 211k in size. They have an attachment that is either a .pif or a .lnk file.
While I have not 100% confirmed it for myself, given the number of these that are coming in I'd say i'm 99% sure that this is another Email-virus swarm.
As always, if you receive an attachment from someone that you don't know, delete it. If you receive an attachment from someone that you do know but they havent told you they are going to send you this (perhaps via ICQ or AIM) then eithe delete it straight away or dont open it until you have verified they expected to send it to you.
Personally I always recommend that you NEVER send attachments and never open any that you receive. If you want to send a file to someone then put it on your webspace or just send them a URL to go get it - and even then, make sure you virus scan ANYTHING you download.
I don't know what the trojan is called, nor do I know how to fix your system if you have inadvertantly been infected by it so I'd strongly recommend getting a virus checker installed and upgraded on your system if you suspect such a thing has happened (generally everyone on your contact list sending you a mail back asking why you sent them such a big message).
If we find anything out, i'll pass it on, if you find anything out then let us know so we can share it.
Oh, and thank you once again for your condolences.
Matt.
