Someone please help me thank you

i need someone's help i downloaded a hack called big bomb v5......

i want to delete it because pb always catches it and i dont want my bro to lose his account because he dont even use it but heres the thing it wont let me delete it.

when ever i go to delete it it says, " make sure the disk is not full or writen protected or that this program is not in use and the program is never in use someone please tell me how to delete it ty.

Hit ctrl+alt+delete, go in processes tab and find something call bigbombv5.exe, click on it and click on end process on the right bottom of the window. If it don't work, simply try rebooting.
