I’ve been getting iexplorer.exe application error

I have been getting iexplorer.exe application error for a couple of days now.
It looks like something is wrong on my browser.
Is this security related error or something?
My antivirus is up to date, and I scanned my pc weekly.
I found nothing on the results.
OS: windows XP
Browser: IE 7
It connects to the internet, but most of the time I got that error.
So for now I am using Google Chrome to prevent that error from popping up on my screen.
Please give me any solutions to this problem.
Thanks.
