HOW TO: Resolve error 2878 when installing ESET

Description: A common error message in ESET, 2878, is due to conflicting anti-virus programs on the machines. Most new computers come with "trial versions" of Norton Internet Security. Follow these steps to completely remove Norton from the machine and successfully install ESET

  1. Go to the Start Menu » Control Panel. Once in control panel, click Uninstall a program (or if view is set to Small Icons, click Programs and Features)





  2. Locate Norton in this list. Double click on it to remove it.



  3. Follow through the Norton uninstall process. Once completed, click Restart Now to restart the computer.





  4. Once the computer boots back up, go to the Start Menu again and type Create a restore point and hit enter. In the window that appears, click the Create button. Give the restore point a name, then click Create. This will allow System Restore to revert to this point if any errors occur.







  5. Now, go to the Start Menu one more time and type regedit and hit enter. Click Yes to the administrator prompt that appears. This will bring up the registry.



  6. Within the registry, type CTRL-F which will bring up the Find menu. In this menu, type Norton and hit Enter.



  7. While searching, a box labeled Searching the registry...Please wait will appear. When it finds a key, this box will disappear. When this happens, hit DEL on the keyboard. Choose Yes in the confirmation window to completely remove the key.



  8. Hit F3 (or Find Next) to allow the search function to continue. Again, when the search box disappears, hit the DEL key. Repeat this process until a box labeled Finished searching the registry appears.



  9. Restart the computer one more time. When it boots back up, install ESET as normal.
