It looks like you still have norton pc checkup installed and running.
Running processes:
C:\Program Files (x86)\Norton PC Checkup\Engine\2.0.3.198\ccSvcHst.exe
Look to see if norton pc checkup is listing in your start menu programs and see if there is a uninstall entry in its menu. If not, you may have to download and run revo uninstaller. From what I've searched, their removal tool won't get rid of this.
Also, click on start, type services.msc in the search box and hit enter. Find McAfee Application Installer Cleanup and change the startup type to disabled if it appears in the list.
