Hello All, I have a Nod 32 2.5 installed on a Windows 2000 Professional Computer. In this computer I have 2 user accounts: a account named guest that is a normal user, without any special permission. A user that can't install or modify programs or system folders. And, the Admin account that is member of Local Admins. I've installed the Nod 32 with admin user. The program updates the virus and other signatures files with no problem when the 2 users are logged, but, the AMON Icon on system tray are showed in red when the Guest user are logged, and the message "amon is disabled" are showed when the mouse cursor is passed above the Nod32 system tray icon. The service AMON are started in services, but, the EICAR test virus doesn't work when I use the guest user. If I put this user inside the Admin group, everything works fine, but I guess this is not the correct solution for this problem. How I can fix this ? I maded a search in the forum and I don't find any suitable help. Regards, MarcSant.
