Welcome to CTH ngaisteve1, it sounds like you have a registry restriction in place. If so, we should be able to fix it with Hiajck This. Go
here and download the latest version of Hijack This to a new folder on your drive, unzip it and click on scan. Most of the files listed will be harmless and/or required so do not make any changes, just click on Save Log, copy it and post it back in this thread.
