Help Pimpy delete file

[Pimpya]

I'd like to delete a movie file I have half-downloaded
But I always get an error "impossible to delete the file" [it is scary to go FURTHER INTO DETAILS] I am afraid I have downloaded a virus
Could someone help me write a program to delete any file / directory on my computer please ?

The error message you have stated doesnt look a standard (OS) message. Also, are you downloading using some download manager ? if yes then first try to close/kill that program and then remove your movie file.

If your file is locked by some program, then it is possible to delete only after terminating the process which is using the file.
