cannot launch IE8

[Guest MXC]

After uninstall CA and install McAfee

My laptop cannot launch internet explorer 8, just not response.

Also I try change home page from control panel-> internet option, but fail,

it automatic reset homr page to microsoft sites.

 

I can only launch the IE8 with 'run as administrator' or in safe mode.

I appreciate any help and suggestion

 

Thanks
