New NIS update causing problems.

Since the new update of NIS I can not access Paypal through Internet Explorer or Firefox, or use windows update unless I disable the smart firewall. I have this problem on 2 machines.

Using "ipconfig /flushdns" , clearing the temporary cache and cookies and clearing SSL state didn't work. I tried a reinstall, didn't help.

If there are other things to try I'm all ears.

Cheers.
