B4339,
Firstly, ZA and Avast get along rather well, and it doesn't matter in which order they are installed.
I would not recommend having XPs internal FW running against ZA. Two firewalls do not always get along, and often limit effective protection or create a "wall" preventing useful internet access. MORE of a good thing is not always good!
Zone Alarm does have some problems at times loading True Vector.
By default TV is configured to run as a service at bootup and continue until the computer is shut down. It monitors and controls internet activity.
If True Vector has never loaded, then you must try uninstalling Zone Alarm according to the instructions at this link. YOU MUST FOLLOW THEM CAREFULLY!
http://www.zonelabs.com/store/content/support/znalm26Main.jsp#xpAnother thing to consider, is that ZA will not run until you sign on to the system....meaning if you do not have Administrator rights, then it will not load TV either.
If ZA is not uninstalled propertly, serious conflicts could result since files will be leftover and a clean install will not occur.
If we are unsuccessful, then we will need to remove all non-essential programs from the startup menu until identify which one is interferring with TV.
PAVEL,
If B4339 is getting a True Vector shutdown, then ZA is not even running, and therefore it doesn't matter what access is granted. True vector is the "active guard" portion of the ZA application. At times, it can be quite tempermental.
This usually occurs when another app interferes with it loading fully.
Good luck
