DUDE!! OMG, djihad.exe is NOT a Mu Online component, that is a hack tool.....
That is a spyware.... This means that your PC is probably infected..
Delete and uninstall djihad and do a full system scan for malware and virus...
FAST!!! and don't log-in to your account yet..
To completely Remove jihad.exe follow
this link suggested by a friend of mine.
(HOWEVER, the best solution would be,,,,
Save all your important files to an external Drive and reformat your PC)
After you have BURNED and PURGED all the jihad files
Re-install whole game from the mainsite
