What is this? How do I delete? Should I delete? suddenly receiving message=

This is not a Microsoft Office question, but you've posted to
microsoft.public.office.misc, which is a newsgroup for Microsoft Office
questions.
A quick google shows that "bo stack" is more than likely a virus, but you
seemed to know that already. Without knowing the exact error message, it's
hard to say for sure, though.
You need to make sure your antivirus application (you *do* have an
antivuirus program installed and running, don't you?) is up-to-date, run a
virus scan, and follow the instructions your program gives you. Simply
deleting files rarely fixes virus infections.
