On our school network we use Symantec Antivirus Corporate Edition 10.1.4.4000. We run Windows Server 2003 on the server and recently upgraded all of our clients to Windows 7 Pro 32 bit. We push the antivirus from the server to the clients. The push seemed to go well but now whenever someone logs on to a client a message pop up saying that a driver was blocked due to incompatibility. There are actually three messages with the third one identifying the drivers - "Symantec TDI and NDIS drivers are incompatible with this version of Windows." What do I need to do to make this antivirus program work? I have sent several requests to Symantec but have not received a response.
