Thank you for your information.
I have another problem with NOD32 v 10 on a Win7 x64 machine. After your configuration hin I installed the trail but I am not glad at the moment. The only way to go only for my is to use a O2 UMTS surf stick and there is a configuration problem. Normal I plug the surf stick in an USB port and get connected to the net. After installing NOD32 I don't get connected as long NOD32 is running. If I stop the protection for a short time (for connection) and start it again after connection everything works fine, but this is not a good way and if I don't get that fixed I will not buy NOD32.
