script.exe is a malicious executable file which is used by Bakain virus. The primary purpose of this file is to start a parasite or launch some of its components. Once executed, script.exe file runs a process that is responsible for the parasite's payload, so you should kill it as soon as you notice this file in your Task Manager. Remember that leaving such files installed on the system may lead you to serious problems, such as the appearance of other viruses, the loss of your important data and similar issues. That's because script.exe is a significant part of a dangerous threat, but it can also work on its own.
For eliminating script.exe file and related malware (Bakain, etc.), you should avoid manual removal because you may leave malicious components that were hidden deep inside your computer.
