There is a application loading at boottime that wants to connect. Use StartUp.cpl to see what is loading and disable it. After that click on the link in my signature and remove all harmfull things from the system.
ns.exe can be a legitimate file or virus/spy-/adware. Depends on what folder it is in. Since disabling it solved the problem you have that file somewhere on your system. Did you enable “show hidden files” while searching for it?
windev.com is unknown to me. Even google has nothing on it. That always makes me suspicious. Scan it with a online scanner and see if that reports it as infected/virus.
