1. The error message “Error retrieving update info file” usually appears when Spybot – Search & Destroy has accidently imported bad Internet Explorer proxy settings. In this case, it helps just to disable the proxy option in Spybot 2. You can access this setting by choosing “Configure Proxy“ in the Updater menu on the left. Or you open the Spybot 2 “Start Center“ and click on “Settings“. Choose the tab “Internet Protection“. Here you can untick “Use Spybot Proxy“. Now click “Apply“ and “OK“.
2. Please check your firewall.
Most people who do not have problem #1 do have Spybot 2 accidentally blocked in their firewall.
3. If nothing else works, you can still use the manual updater, which is available on the website: Detection Updates
