Mydoom
Mydoom is actually a worm that infects the Home windows operating process. It has also been often known as Novarg, Mimail.R, and Shimgapi.

Mydoom has presently created its way into more than one million desktops and has prompted several end users to choose safety measures to shield their equipment.

MyDoom was first detected on January 28, 2004 at about 8am Eastern Regular Time (1300 UTC). The virus's very first documented victims have been in Russia. It spread rapidly - inside 4 several hours of detection, it had presently affected Nearly 50 % the whole world's pcs.
