Computer Slowdown

more options

I wrote earlier about the slowness in my computer that sometimes forces me to restart it that's happened ever since I added the Firefox Private Browsing Feature.

I was asked about my security and I said I use Norton 360. I've also added Norton anti-tracker. Could that be causing the problem?

Thank you.

Thank you very much. I did that and it might have been of some help. However there seems to be an odd bug inwhich refreshing a website I often use seems to slow the internet to a crawl.
