At home, something like ten where I usually see three or four.

At work:

       Total    marked as spam    rejected by     scanner says    Total E-mails

The numbers for 26 Aug. *are* up, but only w.r.t. 22 and 25 Aug. As
you can see, last week was no picnic here.

I didn't install the AV scanner until about noon on 20 Aug., so the
virus numbers are nonexistent or for a partial day before then.
Weekend numbers are skewed because the volume of valid mail is less.
