I have windows vista with Norton 2010 and I had to do a system restore. After the restore Norton came up with some errors about corrupted virus signatures. I thought that maybe I might have to do a re- install, but instead I just ran live update a couple of times and ran an intelligent updater and now I have the secure green check-mark. Is it necessary to do a reinstall or am I OK. It said somewere in the norton instructions that if the live update did not work I would have to do a reinstall, but by the way things look it looks like live update worked. The errors are still in the history log so I don't know if everything is good to go or not. I have some screen shots to help out.
I guess to put it simply, is it necessary to reinstall Norton after a system restore.
this picture is how norton looks now after running live update a couple of time and running an intelligent updater.
these are ther errors I got.
