Cannot access websites through IE

Hi,
I just installed Avast and i found that i cannot access the internet through IE. The yahoo messenger seems to work fine. I can only access the internet if i turn off on-access protection of Avast. I’m using the Nvidia firewall that comes with the nforce chip.
Looking forward to using all the features of Avast.
Thanks,
loybax

ps using my firewall i have allowed the following programs:
ashavast.exe c:\program files\alwil software\avast4\ashavast.exe Allow false true
ashmaisv.exe c:\program files\alwil software\avast4\ashmaisv.exe Deny Allow false true
ashserv.exe c:\program files\alwil software\avast4\ashserv.exe Deny Allow false true
ashsimp2.exe c:\program files\alwil software\avast4\ashsimp2.exe Deny Allow false true
ashsimpl.exe c:\program files\alwil software\avast4\ashsimpl.exe Deny Allow false true
ashwebsv.exe c:\program files\alwil software\avast4\ashwebsv.exe Deny Allow false true
aswupdsv.exe c:\program files\alwil software\avast4

Hi,
I think i already fixed the problem…the ashwebsv.exe was actually denied by the firewall. thanks anyways…
