Can't connect due to Symantec Network Security Miniport

Have a Acer netbook with NIS Netbook edition version 18.5.0.125,haven't been able to connect to Internet for a couple days.

   Looking in Device Manager under Network Adapters I see 5 devices.  The wireless and lan cards are there and appear to be normal with no exclamation points.  There are 3 other entries with exclamation points that have    -Symantec Network Security Miniport at the end. One is the wireless card,one is the network card and the 3rd one is WAN Miniport (IP)-Symantec Network Security Miniport.

   I have tried hooking up a network cable to the router,that does'nt work either. Anyway I can fix this without uninstalling & reinstalling NIS? I am running XP with Service Pack 3.  Also have  another laptop with Netbook edition that doesn't have any

Symantec Network Security Miniport entries under Network adapters.

 

Thanks,
