So, I followed the directions here "Move the downloaded jar files to <Installation dir>/elasticsearch/ES/lib"

My Nessus vulnerability scanner sees old Log4j files here - C:\ManageEngine\Log360\lib\log4j-1.2.15.jar

and also here

C:\ManageEngine\EventLog Analyzer\lib\log4j-1.2.17.jar

C:\ManageEngine\ADAudit Plus\lib\log4j-1.2.15.jar

Is it safe to delete these files??
