Java Virtual Machine is essentially an interpreter that translates Java byte codes into machine-specific instructions. From time to time, you may face issues with Java Virtual Machine during its launch. You may get the following error message: "Java Virtual Machine Launcher could not find the main class: program will now exit." The error is rarely fatal, so you can continue to work, but it is annoying. You can get rid of the error by checking your computer for malware and editing your startup programs.
