The AVG virus scan keeps popping up with this message:  C:\\windows\system32\drivers\ndis    Trojan horse rootkit Agent DI  Critical system file that should not be removed.

Resident Shield Alert   C:\windows\system 32\drivers\ndis.sys

The system is slow and takes a long time to load the MSN Homepage.  I have run several virus scans and they remove or quarantine the trojans but the ones that I mentioned above cannot be removed.
