First, please spell out your words and use reasonably standard grammer. LQ has an international membership and the more readable your posts are, the easier it is for others to help you. Also, the more specific information you can provide about what you've tried, what error messages you've received, and so on, the more easily we can help you.
If I understand your post correctly, you cannot use your built-in optical drive because of a worm. Normally, you install from disk by booting to the disk. I'm curious how a worm can be activated when you are booting to a disk in the drive, when Windows has not yet started to load, unless you have a rootkit, which is an entirely different problem, unless the worm has somehow physically damaged the drive.
If you search for usb linux install in any search engine, you will find no end of links for various distros, or go to the homepage of the distro you wish to install and look for instructions there. The big picture is that you make a bootable USB drive, boot to it, and install from there. The close-up picture depends on the distro.
