Hi there, is there some one who may have already done this and is able to provide me with the right information. I am currently protected with the above 2002 soft ware and in a couple of months need to update with2003 version on disk; Do I have to first remove the 2002 version antivirus before loading the replacement, or is it alright to overite it with the 2003version. I would be greatful for the right guidance. I am very new to using PC software. thanks.
