I paid for the software and after the initial reboot after the software loads the pc will not browse. We are an isp and the network is up and running. This particular machine runs on windows 2000 professional. I noticed in the device manage that avast loads all kinds of Network interface devices. And even if i disabled all of them except the actual nic card the Internet still will not work nor the network. I have un-installed the product and internet comes back up just fine. Please advise I want to use the software to its fullest potential. Thanks
