Worm Nimda is a an Internet worm, which spreads in infected e-mails with attached files. There is no need to run an attachment on vulnerable PC: the worm installs itself to the computer immediately when a user opens the infected message for preview. Then it modifies several computer files to start itself automatically with an operating computer and creates lots of infected files on all available local and shared hard disks. For spreading by e-mail it uses remote mail servers and sends infected e-mails to addresses found in a computer. The Nimda worm causes a security breach, so all remote and local users can access and fully control your PC. Infected computers can be used by the worm to infect other vulnerable web servers and personal PCs.
