NO FLAMING ABOUT NORTON!

I have just tryed to install norton onto my PC, in order to do this I have to delete ‘avast!’, I did this successfully but when I restarted my computer it crashed (every time), I ran the diagnostics and it said I needed to run system restore, I did and my PC started up but now ‘avast!’ won’t work and won’t delete.

Is there a way to delete this without using that special file?

also is that file safe to use?

That file http://www.avast.com/eng/avast-uninstall-utility.html is safe to use. (Make sure Windows firewall (or another third party firewall if already installed) is turned on).
You should first download the uninstall utility, the installer file for Avast (or Norton, if that is your choice) (if you don’t have it already), and the Norton Removal tool. http://majorgeeks.com/Norton_Removal_Tool_SymNRT_d4749.html
Once all is downloaded, disconnect from the net.
If it is possible to remove either or both programs via the control panel, please do so. Quite likely you won’t be able to.
-Reboot into safe mode
-Run the Avast uninstall Utility.
-Run the Norton Removal tool
-Reboot into normal
-Install the Av of your choice
-Reconnect, get updates.

Sure thing. Why would anyone need to flame Norton, here? It's its' own best friend. ;D

  1. Remove NAV or Norton 360 through Add/Remove programs from Control Panel. Boot.
  2. Use Norton Removal Tool for Windows 2000/XP/Vista or Norton Removal Tool for Windows 98/Me. Boot.
  3. Install avast! (or repair the installation) and boot.

The Norton Removal Tool uninstalls all Norton 2008/2007/2006/2005/2004/2003 products and Norton 360 from your computer.

Then, I suggest an installation from the scratch:

  1. Uninstall avast from Control Panel first.
  2. Boot.
  3. Download the latest version of Avast Uninstall and use it for complete uninstallation.
  4. Boot.
  5. Install again the latest avast! version.
  6. Boot.
  7. Check and post the results.
