    In the latest update, I see that Eset has:

    NOD32 - v.1.1063 (20050415)
    Virus signature database updates:
    Changes in existing signatures

    What does that mean outside of Eset changing exisiting signatures? What were the changes?

    It means that some other files belonging to a particular threat were added to an already existing signature.

    The land of no identity :D
    A change in existing signatures can mean a lot of things:

    1)Improvement of signature (this can be done to stop some trick methods used by the vx coders to bypass detection)

    A good example is an old case of McAfee, where the signature of an existing malware was so weak that changing the icon of the malware executable made McAfee not detect the malware.

    2)New, faster/better/more efficient methods of cleaning the malware
    3)Modifying the signature to include more detailed information for a minimum chance of false positive.
