Mydoom is a mass-mailing worm designed to install itself onto your machine without your knowledge and permission, either bundled with other malware, as an illicit email attachment, or via security exploits. Once it is installed, Mydoom will spread its copies to several locations, including peer to peer file sharing directories. Mydoom will search for email addresses in your PC and spread by emailing itself to all entries in your Outlook address book. In addition, Mydoom will open a TCP connection on port 3127, and this will allow your computer to be controlled by the remote attackers. Some versions of MyDoom can remove some files, including personal documents, images, etc. and terminate antivirus processes. Mydoom opens a huge security hole on your machine and puts your personally identifiable information at a very high risk.

To check your computer for Mydoom, download SpyHunter Spyware Detection Tool.
