Mytob.c held off a strong challenge from Nyxem.e to top the July virus chart. In June, Nyxem.e stormed the virus chart, re-entering at number two after a lengthy absence. The virus was expected to nab the number one spot in July, but Mytob.c proved too strong, edging out Nyxem.e by just one per cent.
Kaspersky Lab also highlights the fact that we are about to enter the month synonymous with huge virus outbreaks. Alexander Gostev, senior virus analyst, at Kaspersky Lab, says: "August is traditionally the month for epidemics. We saw Lovesan in 2003, numerous Mydoom variants in 2004, and Mytob/Bozori (aka Zotob) in 2005. However, nearly all of these outbreaks were preceded by the disclosure of Windows vulnerabilities. So the answer to the question whether there will be an epidemic this August will depend on whether new vulnerabilities are found."
