I recently was targeted with a virus laiden email attachment.  I have
Norton for security, and it picked this up with no problem.  It
couldn't manually delete the virus, so it quarantined the message.  I
have google as my home page, and as I went about my usual activities,
I hit the drop down window in the google address bar. . .there I found
the quarantined file--Needless to say, I didn't type in in there. 
What gives???
