Vista connects internet automatically

[icekid]

My System: Inspiron Desktop 530
OS: Vista
RAM: 2GB
Intel Core to duo.

Problem: Internet connects automatically in Windows Vista and I cannot disconnect. When I forcefully disconnect i.e switch of the modem a message comes up "Remote connection problem" or something. I did a virus scan using avast, there are no virus.

Can someone please help me. Thank you in advance.

Which type of Internet connection do u have mention it first?

Hoping if you are using Dial-up Broadband, then choose the option "Never Dial a Connection" in connection section of Internet properties. After that the Net will be connected after your dial only.

By the way check your system for Spyware/malware/trojans which automatically dial up the connection. Update the AV and can use the tool "COMBOFIX" (google it to d'load) to remove any unwanted programs.
