IE 10 changes after installing NIS

I bought a laptop with windows 8 and a trial version of another antivirus software.  I installed NIS because I had almost a year left on my subscription.  When I did this, many pages would not load pictures anymore, some menus on websites I have to use for work wouldn't appear anymore.  When I tried to sign up for this forum, I couldn't see the Captcha sign to verify my login information.  I'm currently on my ipad trying to resolve the issues.  I tried uninstalling NIS, but am still having the same issues.

 

Any help?
