After updating Samsung galaxy S3/S4/Note 2/ Note 3 to Android 4.3 jelly bean update which contains the new security from Samsung "Samaung KNOX", you might face a problem if you tried to root your device by using CF-Auto-Root method or other methods.

This might happened because of KNOX security, it block/disable SuperSu app and you will see this notification after the first boot.

"Unfortunately, SuperSU has stopped" 

"Unauthorized access to a secured area has been blocked"

In some cases you will not see SuperSU after rooting in your application list
You can enable it by going to Settings / More / Application manager, Swipe to DISABLED tab and Enable SuperSU app.

How to fix KNOX problem :
1. Go to Google Play, Search and update/install SuperSU app
2. When you will open SuperSU for the first time it will ask you to update the SU binary
3. Tap on "Continue" then "Normal" not the "CWM/TRP".
4. SuperSU will detect Samsung KNOX security and will ask you to disable KNOX, Choose "OK"
5. After displaying "installation success!", reboot your device.
Done !
Now SuperSU and root access should be working fine for you.

How to fix "Unfortunately, SuperSU has stopped"

Download and install the latest APK for SuperSU like MrW0lf suggested.

I was having the same exact problem (unfortunately, SuperSU has stopped), so I downloaded the latest UPDATE-SuperSU file and extract it to have supersu APK, put it on my SD card in my phone and installed it from there.

It was strange because the version that was already on my phone was the same 1.89 version that I downloaded, but regardless, when I clicked on the APK, it saw it as an update, it asked to disabled knox, and worked like a charm.

SuperSU Google Play
SuperSU Pro Google Play

Was the pop up dialog which appeare every time I
turn on My Pc or restarting.
It was annoying massage to get ride of it for good and for all.

This massage is caused by verecno Worm
