    ..just tonite I heard part of a conversation.
    ..They mentioned an email virus that sends you mail attatchments from addresses that YOU yourself have ether viewed or sent mail to....in other words, it 'spoofs' addresses that you've viewed or sent mail to.

    There are many Worms that upon entry to one system retrieves the persons Address book information and sends itself to addresses listed. This increases the chances of speading since the receipent will think the E-mail is from you or from someone they know. That is why it is important to have an up-to-date virus scanner on board checking your E-Mail as it is being received and better yet going out to since it may be you who is infected.

    Klez virus uses this method I believe but there are many others.

    ...The way those folks were talking, it sounded like: once the worm//virus enters your machine then sends something BACK to you as an email with attatchment--[using an address that you know//trust].......does that make any scense??

    Hi unstresst,

    that makes sense to me. Thats exactly what a worm virus does.
    Make sure you have you anti virus programme up-to-date.
    I had a nasty worm virus about 18 months aga ( worm_sir-cam) and because I didn't have my AV updated, the virus went on to infect people in my outlook express address book.

    The Klez virus does what you're talking about. Once it infects a computer it starts mailing itself out to addresses in the infected machine's address book.

    In addition, it uses a randomly selected address in the infected machine's address book to use in the "From" field. It will then look like the message came from another computer, thereby making it impossible to determine which system is actually infected so the owner can be warned and the virus cleaned out.

    If the infected machine has some invalid addresses in its address book and the virus mails itself to one (or more) of those invalid addresses, the message will be bounced...and it will bounce back to the address in the "From" field, which is not the orginating, infected machine.
