Javaw.exe is a legitimate file related to Java software
Javaw.exe is a legitimate executable used by Java Runtime software, published by Sun Microsystems.[1] Therefore, do not be surprised if your Task manager is displaying this file if you previously installed any product from Java – even if you removed it. Nevertheless, some applications running Java might get jeopardized because of the incorrect uninstallation – that is when users encounter problems and various error messages.
Just like any other executable file, Javaw.exe can be abused by cybercriminals. Malware[2] is known to replace or duplicate legitimate file, mimicking it. And, because some trojans, spyware, keyloggers and other malicious software might lack symptoms completely, making it hard to detect and eliminate.
