For the U.S. that might be only a little low.

For some other locales, like South America and parts of the Pacific Rim, you're *under-estimating* the problem by an order of magnitude. I've seen numbers like 1 in *8* for some areas. *groan*

That should be "obvious" -- given that there are fairly reliable estimates of 200,000+ 'zombie' machines on *one* large North American cable ISP.

[TELECOM Digest Editor's Note: One thing I really love about Cable One for internet is how they go to the trouble to sort email for their customers. I've quoted some stats here, and those stats are _only as they apply to massis and Telecom Digest_ . My personal email comes via Cable One, TerraWorld, and University of California at Berkeley, but Cable One picks it all up via POP for me and sorts it nicely, putting all the known viruses and the suspected spam into a separate folder called 'my spam'. Then it sends me email telling me to please check out 'my spam' when something arrives there (which is sort of an overkill; viri and spam arrive there constantly also.) When I go to look there, its all laid out nicely, 24 lines at a time with the subject, who it is from, the date, etc, and nice little convenient check boxes to one side and a box at the bottom saying 'check all'. As fast as I can scan those 24 lines and hit the 'check all' box, it all goes away. In the event there _is_ something there I want to keep rarely, I 'check all' then go back and uncheck the one I want to keep. Anything I uncheck to keep then is shown on the training page: do you want to have this sender/subject automatically approved henceforth?

I just wish that SBC's DSL had been that courteous. Under some very misguided belief that "we do not get involved in our customer's email" they just dumped it, spam, viri and all into a common bin and left it for me to sort out. Of course, SBC does _not_ allow customers to run cgi-bin or any shells of their own, or any scripts, so I had to go through it all manually. Out of desparation once, I asked the SBC help desk (when I used to have DSL instead of cable) to please give me a shell. "Oh no," said the tech, "SBC does not let customers have shells to use. You are only authorized to use what software we give you." That's back when I was debating whether or not to stay with SBC for DSL only, if they had allowed such a thing. Cable One is such an improvement by comparison, and I have never seen any downtime. In addition to their own virus and spam detectors -- frequently updated -- they encourage people to run their own as desired also. PAT]
