error signature

i realy need help to fix this internet explorer error
thanks for the help...

error signature
appname: iexplore.exe
appver: 7.0.6000.16735
modname: kernel32.dll
modver: 5.1.2600.5512
offset: 00012aeb

When did this started? Did you installed something? Remove it.

I had this problem too( suddenly the IE can not open the thread, and a message: Internet error signature)
And people advise me to do the following steps:
-open IE
-on the Tool->Internet options->advanced tab-> uncheck the enable third party browser
and that's fine
