Internet stopped working; still connected to network

os:vista ultimate x64 w/ all updates.

my firefox & IE have suddenly stopped working (blank page; "website
found; waiting for reply" on IE and "waiting for xxxxx.com" on firefox)
.. literally. one minute they were working, the next minute they weren't.
i didn't do anything special in between. not even a reboot.

now, it's only IE and firefox; messenger still works and so does skype
and some other internet apps.
i can even ping yahoo.com from cmd.

- i've tried rebooting, no help.
- I've tried reinstalling firefox, no help.
- i've tried switching from wired connection to wireless; no help
- i've tried disabling firewall; no help.
- i've run anti-virus (nod32) and anti-malware; no help
- It's not the router or ISP, because my laptop works fine.

and finally, this problem happened to me about 4 weeks ago; i was
unable to find a solution, so i reformated and reinstalled vista! now,
it's happened again. grrrrr...


more info. i tried a system restore back to when i know my pc was
working fine. and the problem hasn't gone away.

also, new piece of info. i can connect to 192.168.0.1 (router's
web-config) through firefox and IE. So that removes the possibility of
something blocking port 80 on my PC.

tried to telnet google.co.uk 80. & that was no go.

try using IE and going to windows update and see if it gives an error
and let me have the error number and btw thanx for the hijack info and
the only thing I seen that was suspisious was this

HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant

try uninstalling this program and see if that helps....

try opening msconfig and go to the startup tab and uncheck everything
and apply the seetings and restart the computer and if that works then
there is somthing running that is blocking the IE and FFX k.....

keep up the good work and if nither SBot or the other stuff could not
find any then your safe but I would still try smitfraudfix and smitrem
to uninstall andy spyware and malware that you may have...

try windows internet connection wizzard somewhere in there if you know
where that is?

try the msconfig and get back with me k... thnx again...

Thanks for your help mate. I haven't tried your suggestions yet. but I
just have come across some new info that might be very helpful:
Everything works when i reboot in "Safe Mode with Network". What does
that mean? Driver conflict?

i figured it out. It was NOD32 clashing with utorrent. Fix can be found
here: 'forum.utorrent.com / HTTP 400 error with NOD32? Look here!'
(http://forum.utorrent.com/viewtopic.php?id=36876) Thanks for helping.

I don't know what NOD32 is, so I don't think I have the same problem.
But this week suddenly IE7 started randomly being unable to connect,
even though all my other internet applications continued to work
(outlook; wireless netwok connected, etc.)

It will start up fine. I will be working in another window. I will come
back to it and IE has stopped working. This has happened 3 times in the
last 3 days, and restarting makes it work again (as evidenced by the
fact that here I am posting).

I will try the various other suggestions mentioned in the post.
