Missing Norton Toolbar & IE 9: Solution Found!
I am an experienced IT user and system builder with many years of experience with Norton products. I searched all over Google, Norton and MicroCRAP for a solution to this issue. There were NONE. Naturally, there was a solution for Firefox listed here on Norton's own website, but no solution for Internet Explorer 9.
Furthermore, you can enable and disable the toolbar extensions in "manage add ons" in IE9 all day without results as I tried 4-5 times myself. Moreover, I also "restarted" my desktop 3 times which also accomplished no positive results!
It dawned upon me that I had that problem once before. Summarily, after a quick look at IE9 I discovered the solution was quite simple.
You must go to Internet Explorer, Internet Options and then click on the "Advanced" tab. Under "Browsing," you must check the box for "Enable Third Party Browser Extensions."
Restart IE9 and Norton will miraculously reappear.
