CAV error 003 when guest user logged in

When Guest user is logged on and than the CAV error 003 is seen.
The details of the Comodo programmes on te laptop are :-
CAVirus=2.0.12.42; Build Version=2.0.17.58 CFPro=2.4.18.184

My OS details are :-
Microsoft XP Media Centre Edition Version 2002 with SP2

I did have Virgin Media’s PCGuard, but this was un-installed before replacing it with Comodo

As an experiment that might shed some light on this problem:- I gave administrator rights to the GUEST USER and got him to log on and found that there were no problems but as soon as the GUEST USER was taken off administrator rights the problem error reappeared.

I GOT IT TO WORK!!!
Here’s how I did it; install CAV firewall pro
reboot
uninstall all antivirus software
reboot
install CAV beta2

Beware any Symantec software, it seems to really hate it.

Great news that you’ve managed to fix your problem. Yes, Norton is “Notoriously Bad”
