i am constantly receiving e-mails which are supposedly
from "public support" at microsoft, subject "newest
network critical upgrade,or bug announcement" also a
returned e-mail which i have no knowledge of ever
sending, supposedly to
rrqstiv@bigfoot.com
norton keeps deleting the offending parts, but how do i
stop them reaching my inbox?

At best you can ask your ISP to filter the incoming mail.

The messages are coming from computers that infected with the Sven virus.
This virus sends itself out as an email message claiming to be a Microsoft
security patch. If you run the attachment, your computer will be infected as
well.

Microsoft never sends out patches unsolicited by email.
