Need Help_ IE8

I use the wordpress to do my website. Everything is working fine on Safari and firefox. However, When I open in internet explorer 8, the text inside(auto become orange color) the article have the link to other website. I never set up like that. They all come from automative. I really don’t want the ad come out from my site. Any one know how to fit this problem? or have any online tutorial to delete the ad? I prefer to see the video tutorial, because I am not than good at coding.

I use the iFeature 2.1.1 theme
Plugin include: appointy, featured page widget, formidable, jquery lightbox for native galleries, the events calendar, tubepress and wp maintenance mode

I did try to deactivate all the plugin, but the problems still exist. and I also try too ask the founder of the iFeature, but they said that this is nothing to do with their theme.

I think all my problem is happen in the text become orange color, and have the ad link pop out when I click on the word.

Please help me. My website address is https://mlz.mcreativedesign.com/about-us/
