I am very sure that SpywareBlaster is blocking Norton Anti-Virus Live Update from working independently. I have not done as suggested and unblocked sections of the program. However, when there is an update available I have disabled the whole program and initiated live update from the Scheduled Tasks screen and it worked. I then enable the program and NAV then refuses to update automatically. Something is not right. Is this going to be fixed? I am sure that others must be seeing the same thing. There must be a lot of people using NAV who are also using SpywareBlaster.
