Code 39 error on network cards due to virus

Hello,

I wonder if someone could help me? I recently had some virus trouble on my PC, and for some reason now I cannot access the internet as all my network adaptors all come up with an icon (yellow circle and black exclamation mark). On checking this it says that this is a code 39 error and that the driver may be missing or corrupted.

I have tried uninstalling the adaptor software and reinstalling it, but it still comes up with the same message. The same thing happened when I added a new adaptor to my PC.

Is there anything else that I can do do try and rectify this issue and get connection to the internet?

Hope someone can help,

Iain
