Installing Norton Antivirus on Windows 7 made some other programs disappear
Last week I purchased a 3 licence version of Norton Antivirus 2013. I started by installing it on my Sony computer with Windows 7. After the reboot many of my programs, like Internet Explorer and Steam, had disappeared. I tried rebooting some more times and running installation of NAV again, but the programs were not coming back. In the end I did a system restore, and all the old programs were there again.
My problem seems similar to the problem described in http://community.norton.com/t5/Norton-Internet-Security-Norton/Internet-Security-2012-has-removed-all-my-programs/td-p/654821
How come this issue has not been fixed in the 2013 version?
Is the solution to this still to make a Windows backup as described in http://community.norton.com/t5/Norton-Internet-Security-Norton/Internet-Security-2012-has-removed-all-my-programs/m-p/655479#M194320 And then try to install it again?
Have I lost 1 of the 3 licences now when doing the system restore?
Thank you in advance.
