Mytob.c held off a strong challenge from Nyxem.e to top the July viruschart. In June, Nyxem.e stormed the virus chart, re-entering at numbertwo after a lengthy absence. The virus was expected to nab the numberone spot in July, but Mytob.c proved too strong, edging out Nyxem.e byjust one per cent.

Kaspersky Lab also highlights the fact that we are about to enter themonth synonymous with huge virus outbreaks. Alexander Gostev, seniorvirus analyst, at Kaspersky Lab, says: "August is traditionally themonth for epidemics. We saw Lovesan in 2003, numerous Mydoom variants in2004, and Mytob/Bozori (aka Zotob) in 2005. However, nearly all of theseoutbreaks were preceded by the disclosure of Windows vulnerabilities. Sothe answer to the question whether there will be an epidemic this Augustwill depend on whether new vulnerabilities are found."

Almost all new threats recorded in July were trojans. The most
successful one was Yabe.R, which caught 29 hours before the first
signature was released. End-user education remains the main hurdle to
stopping email viruses.
