The SymNRT (Norton removal tools) have been extensively used in these forums by many ex NAV users and I haven’t see any issues, so perhaps you can expand on the comment “The software breaks BITS?” (stated by Reviewers of the removal progam) ?

Do you mean lots of different things or are you referring to the BITS (background intelligent transfer service) which is a required service if you want windows update to work.

Transfers files in the background using idle network bandwidth. If the service is stopped, features such as Windows Update, and MSN Explorer will be unable to automatically download programs and other information. If this service is disabled, any services that explicitly depend on it may fail to transfer files if they do not have a fail safe mechanism to transfer files directly through IE in case BITS has been disabled.
