5. Check computer for viruses
There may be malicious software on your computer that is preventing MATLAB from behaving correctly. You may need to repair your system before MATLAB can be used.
6. Disable antivirus software
If your antivirus software has not been able to find any malicious software, it may be what is causing MATLAB to malfunction. Try disabling it and then launching MATLAB.
