if you have a firewal installed could be blocking the updates disable it see what happen.
Running Dell Dimension 8400 PC. 160g HD, 1g RAM, Windows XP SP1 and SP2. In addition to SpyBot Search and Destroy and Ad-Watch SE Plus I have Microsoft Anti Spyware Beta 1 and CounterSpy Version 1.0.29 and Definition Version 105. A couple days ago received mail for update to CounterSpy bringing it to current 1.0.29 version and raising Definitions to 150. Definitions remained at the old 105 instead of going to 150. Since initional instalation of both Anti Spyware and CounterSpy have not been able to install updated Definitions in either program. When I select upgrade in either one I receive the same message saying: "Warning: Could not connect to internet." I am connected via DSL, not the light, and have no problem downloading Norton updates. IE is not set on maximun security. Any halp will really be appreciated. Chuck in NC.
