I could be wrong, but There is a program, DL.exe which does just what is discussed below. It sends spam to email addresses that are on a computer that it infects. That's part 1. Part 2. recently I acquired a couple NetGear WiFi cards to add a couple old laptops to our network. The NetGear software is designed to find a network at install. This is done without any window requesting if the network the software has found is OK to use Part 3. There are several WiFi networks in the neighborhood. One of them is unsecure, and contains DL.exe on it. I never saw something download so fast. Fortunately, that program causes a command box to pop up, so I knew it was there, and could deal with it. Moral: Install netgear cards during the wee hours. Select the appropiate network. Do a search for DL.exe. Edit registry. Otherwise I, too, could become a spammer.

But I cringed at that naive suggestion. Whether or not you get spam has little to do with your platform and much more to do with your online exposure and use of your email address. I will say that there is a huge difference in susceptibility to viruses and trojans and so on depending on your platform. I would further point out that the huge quantities of spam on the internet are a consequence of the huge numbers of compromised Windows PCs that comprise the botnets that are used to distribute spam, and that make it difficult to block (because it is coming from everywhere). So, if we *all* switched platforms, . . . well, but that opens the hypothetical question of whether the dominance of Macs would lead hackers to focus on them more and end up developing ways of accomplishing the same thing with Macs. I don't think so, but, then, it's hypothetical. From an ecological and evolutionary point of view, perhaps a more diverse stew of operating systems with no one dominating would be better. However, I don't think we could be much worse off than with Microsoft being dominant. Some people say that 80% or more of the traffic on the internet is spam. I've even heard some claims of 90+%. There are also indications that there are several botnets that are on the order of millions of compromised PCs. If one of them wants to shut down a major site with a denial of service attack, they can. And they have. Just as a small example, two of the mail servers I run, which are on separate domains and subnets, were each being hammered about 3am this morning from a site that was continuously changing it's server's names in the smtp envelope. At first both our servers were rejecting the connections because the server names looked to be forged. Then both our servers began rejecting the connections because our allowed connection rate from a single site had been exceeded. However, even while rejecting connections, this still takes processing time. Both of our servers were showing high peak loads that would have made them slow to respond if there had been users trying to do things on them (but it was 3am). Were it not for viruses, trojans and botnets, being a sysadmin would be a lot simpler, and we would all be more productive. I should note that, overall, the suggestions you got seemed informed and helpful. > Switch e-mail client interface to Mozilla mail (Thunderbird), it > probably will reduce spam.
