Matlab will not open. Two files \Downloads\temp_Matlab_R2018B and \Program Files\Matlab\R2018B\ have been quareteened by IOLO my security system. Can I simply send both files to trash and then get a clean download ? If not what is the process to get Matlab back up?

Hi Charles,

You can perform the following steps in order to get MATLAB backup:

• Take a backup of your 'pathdef.m' file, which can be located by using the command

which -all pathdef

• Before proceeding, ensure to make a safe copy of the file by copying it to a folder outside of your MATLAB path.

• After taking the backup, execute the following commands in the MATLAB Command Window to restore the default MATLAB search path and rehash the toolbox cache:

restoredefaultpath
rehash toolboxcache

• Use MATLAB to see if the issue occurs again. If the issue is resolved, then save the new MATLAB search path by executing the following command:

savepath

This might remove any custom path that you have created.
