The MyDoom (or Novarg) virus is another worm that can make an indirect access in the victim PC's working framework. The first MyDoom virus - there have been a few variations - had two triggers. One trigger made the virus start a denial of service (DoS) attack beginning Feb. 1, 2004. The subsequent trigger instructed the virus to quit dispersing itself on Feb. 12, 2004. Even after the infection quit spreading, the indirect accesses made during the underlying diseases stayed dynamic ³⁾.
