Worm Virus to lay dormant till Oct???

I am hearing so much about this virus that is spreading from srever to server. I hear Win 98 is going to pull through just fine were outher operating systems are going to catch it. Does anybody know anything about this worm and is it going to shut down computers all over country? Will it creep into our computers and open itself up in Oct?Do we continue to open our e mail attachments? If you do you may already have the worm.
