KUDOS TO KEN EDMONDS :-)
THANK YOU KEN!
I performed ALL of the steps AVG had suggested to no avail. I actually thought that a SERVICE or PROGRAM may have been the problem so I DISABLED a lot of SERVICES and removed a lot of PROGRAMS. Still not working. After seeing your resolution TODAY I set Terminal Services (which is one of the ones I disabled as a last resort to get AVG working) to start AUTOMATICALLY and though I had a problem STARTING it I eventually was able to (SEE BELOW) and BAMM AVG started working as designed! 
SO TERMINAL SERVICE SERVICE IS THE KEY. Set it to automatic and start her up to resolve this ugly mess.
Under SERVICES in XP Administrative Tools RIGHT CLICK on Terminal Service and select PROPERTIES. Once in properties select the Startup Type - AUTOMATIC. THEN CLICK ON THE LOG ON tab and ensure that the HARDWARE PROFILE for your system is enabled. If not, enable it (touch nothing else here). NEXT go back to the GENERAL tab and START the service in the Service Status area. This should START and set Terminal Services to AUTOMATIC on system boot. Now that it is Started you can exit Administrative Tools and try AVG - I think you'll be happy

Hi, I'm using AVG Zen. When I'm trying to access the software to update it, it says : UI Failed to load. This is really embarrassing. AV Service is not responding.
When I click on restart, it just goes round in a circle,
Please help.
Thanks
After restart, run AVG Remover and remove all other supported products and remnants of AVG (ZEN, Framework,…).
Open AVG_Remover.exe (http://download.avg.com/filedir/util/AVG_Remover.exe)
User Account control - click "Yes"
Click "CONTINUE"
Select all products, and click "Remove"
Click "Restart" and restart PC
If is displayed dialog window (Open file – Security Warning) after restart, click "Run" and let AVG Remover remove traces
If is AVG Remover asking for restart PC, restart PC again.
