False Ammyy Admin detection

Hello,

I buyed Admin Admin v3.5 for my business to connect to my clients.

Why is it impossible to install Norton AntiVirus or Internet Security and not to loose the program (on my computer and on all my client's computer) and all my contacts and parameters ?

If not a solution is found rapidly, I must change my antivirus supplier (for my business and for all my clients !)...

Regards,

F.Schneider
