Answer 1

You need to turn off system restore then run norton; then turn off your computer; then turn on - run norton again then turn system restore back on.

Answer 2

Sometimes it gets blocked up or it very "lazy". I usually scan it every day superficial and once a week very deep because staying on the internet for more than 5 hours/day i usually get make spywares and adwares. When nothing is working i simply reinstall windows because in my opinion nothing can be done

Answer 3

You need antivirus software, such as Norton which you mention, or AVG (free version). You should download 'Ad-Aware' by Lavasoft, as this is free, and it checks for spyware that you probably have on there. And - while you are at it -- try not to forget ZoneAlarm - it has a free version of a firewall that would also be useful-!

Answer 4

Sounds like Norton is doing it's job. Might be you keep getting reinfected, and Norton is catching it.

Do full scan on your drive.

Also, I would recommend installing Microsoft Defender (it's free) to help out.
