How do you know if a bat file is malicious or a virus?

Do you already know if it is a real bat file or another type disguising as a bat file?
If it is a real bat file, change the extension to .TXT and open it with Notepad. Try to understand what it does.
The reason I'm suggesting to change the extension, is to prevent you from launching the bat file by accident.

If you don't know, I suggest you upload it to http://www.VirusTotal.com
