In my system internet explorer and mozilla both are installed but internet explorer is not able to open websites.
IE has very poor security, so it's commonly targeted by malware. You might want to follow the suggestions in this thread, then post back with your results. Best regards, -AT
If it does not work right for you, then do not use it...IE is the worst browser to use anyway... I never use it. most of the time I will just remove it..
