(ok is the time to buy new one   )

because the smebox become buy for looong time.
i´m really with a virus like the live postmaster said ?
or the problem is other one?
how i can make a fast scan and see if i have virusers?
and how the post master can see viruses on my server if i send a mail to my self on gmail
