Hello,
Do you have a firewall installed? If so have you authorized SpybotSD.exe to access the internet?
There is a good chance that the cause of the problem is a firewall or proxy problem.
If you sitting behind a proxy server:
Go into Spybot > Mode > Advanced mode > Settings > Settings. About 2/3 of the way down the option tree there is a category "Web update". Check the last item in the list "Use proxy to connect to update server". A pop-up will come up were you can enter the information required.
If you have a firewall:
Reauthorize SpybotSD.exe to access the internet within your firewall. If you have a firewall and are not sure if that is the cause of the problem, you could (for a short period) disable the firewall and see if the updates work properly.
If Spybot-S&D is not blocked it is also possible that our server is temporarily not available. Please try it again a few hours later.
If this does not help please download the updates manually:
