Netsky.q has been pushed off the top of the virus charts for the first time since 2004, according to monthly statistics released by Kaspersky Lab. Netsky.q has been the most widespread email worm since 2004 and its variant Netsky.t has risen rapidly since the beginning of 2006. However, both worms fell away sharply in June, with Netsky.q falling to 15th place and Netsky.t to 20th.
Kaspersky Lab said that it was possible that both worms will disappear entirely from the company's next top 20 list in July. The other surprise in June was that Nyxem.e returned to the charts, becoming the second most encountered virus.
