According to BBC, one third of all spam is sent from home computers. Only few can use operation system at homes as skilfully as it is used in local networks of companies, and due to throughput it is possible to transmit significant volumes of data.
Viruses, in particular, worms prepare home computers for using them as sources of spam. In January 2003, Sobig was the first virus of such sort. Then came Sinit, Fizzer and MyDoom. Epidemic of the last became the most scaled over the Internet.
Infected computers are not the objects of the attack. On the contrary, virus tries to remain unnoticed. However infected computers (in MyDoom case hundreds thousands of computers were infected, some experts consider that they amounted half a million) set up a spam network that spread spam.
Before development of technologies that will in principle take away anonymous email distribution, it is necessary to detect network addresses of infected computers. Announcement of lists with such addresses is an efficient way to make owners of infected computers to get rid of viruses that spread spam (outgoing mail from infected computers will be refused by mail servers and this is serious stimulus for "curing"). "Black lists" of infected computers are filed today too but privately. It is inevitable in the nearest future that either each user will become a system administrator or paid software support of home computers will be rapidly developed.
