I can get full access to the web but now (I had an update by windows) get through to just one website "netfirms.com". Not even by going to a search engine and then clicking on the connection. I have the same problem with my computer and windows tablet. Both have Norton Firewall. Netfirms is an established company and I have websites hosted by them. On another computer at a different address I went straight through. Whats the problem? How do I overcome it?
