How do those programs behave if you boot into Safe Mode and try again?
Dear wizards, can you help with the following problem?
[+] Firefox works
[+] downdloading files works (antivirus/Java etc.)
[-] antivirus/Java etc. installation gets interrupted (error message: 'current settings prevent a connection to the internet')
[-] Internet Explorer (backup browser) starts ok but does not open any pages at all.

[Windows Vista SP3]
Thanks for your help.
