Occasionally, your IP stack can get really goofed up. When trying odd antispyware apps that hook into the IP stack, sometimes things just plain go wrong, not to mention the spyware that needle in there. There is an easy way to clean this up. Issue the command:

netsh winsock reset catalog

and this clears out all the things that are hooked into the IP stack.
