I had to restore my computer to a previous day & now Norton doesn't work nor Firefox. IE does but I never use it just firefox. The Norton was put on in Jan 2012 & it is the one from Comcast.net. It doesn't do anything except say C:\Program Files (x86)\Norton Security Suite\Engine\5.2.2.3\uistub.exe Unspecified error. I use win7 on a laptop & always use Firefox. What do I do? Thank you.
