No, batch files will always open a commadn window and show their progress to the user. Also batch files must be run by the user or be called as a child process from another program.

Yes they can be "trojan"-viruses batch files can delete files and start other programs. However there's always a screen popping up letting the user know what's happening. Quick scripts that finish quickly will close the screen in less than a second.
