New forum person. I have been happy since using Norton 360. I am a novice in all aspects of what is best in regards to installing updates as provided by Microsoft Windows 7. I experienced problems during the last Security Updates and worked with Norton to resolve. I now have 11 more important updates and 9 more optional updates. I have taken manual control of all updates. I now want to understand if I should forego certain updates because I am using Norton 360. I am especially uncertain about installing the Windows Malicious Software Removal Tool (KB890830). Any help is appreciate.
