Does Avast conflict with Norton?

Avast Free Antivirus / Premium Security
1

I plan to uninstall Norton and get Avast instead, after it was recommended to me today. Does anyone know if I have to uninstall Norton first? A while ago I installed AVG which resulted in a conflict with Norton and I had to uninstall AVG as I didn’t know how to get rid of Norton.

Download Avast first and the Nortons removal tool
You will have to remove ALL remnants of Nortons or you will have serious issues installing and running Avast.
Go through the normal control panel /Add Remove (Nortons removal) process. Reboot
then go to Symantec link http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2005033108162039
Download and run the Norton Removal Tool appropriate to your product. Reboot
Avast should install and run like a charm now.

It is more a question of what does Norton conflict with and the answer is almost everything even when uninstalled there are often remnants which continue to conflict with processes. So it is essential to not only uninstall using add remove programs but also the tool tednelly gives the link for.
