The "Automatic access configuration for PC" is not a "dialer" (software that connects itself to Internet), which can often be found in the Net. Only the settings for the Internet connection through SUNWEB will be stored on your PC. You will always be able to delete these settings, deleting the Internet connection called "SUNWEB".

Executing this special "script" your Windows operating system will store automatically all the settings you need to connect to the Internet over the "SUNWEB Dial-Up" service. You can use this service only from within Switzerland at the price of a local phone call.

The script is using a feature of Windows with Internet Explorer (version 4 and newer) called "Internet Autoconfiguration".
No software is installed and no software is changed, only the access data for "SUNWEB Dial-Up" will be stored as a new Internet connection.
