Win8.1 new upgrade, Samsung 780Z laptop (fairly new). It's my granddaughter's, she uses it for Photoshop and photographic work. It had stopped connecting to the internet, which is why she asked me to look at it. I cleaned out a bunch of junk via Ccleaner, Spybot:S&D, and NortonAV, but there is something left that's preventing Windows Firewall and Norton from starting; and I cannot get them to start manually.
I'm not real familiar with Win8.x (I'm on the bottom of the learning curve), the last time I had a similar issue was with XP, and I've never had the issue with 7. I remember something about a removal tool, but that's it.
Any help will be most appreciated. TIA.
