Draggdor is a worm that spreads through unprotected network shares. It also creates multiple copies of itself in all local folders. The parasite opens a back door providing the attacker with unauthorized remote access to the compromised computer. The intruder can download and execute arbitrary files and change the default Internet Explorer home page. Draggdor is able to terminate running Symantec antivirus software. The worm runs on every Windows startup.
