Hi - Yesterday my HP laptop starting doing this. It shows that I am connected to a network, but when I open up Internet Explorer it says page cannot be displayed. When I ping a website I get 4 replies. I also reset the WINSOCK entries, deleted cookies and temporary internet files, and did a virus scan with nothing found. I tried all I can think of and what I found online. The operating system is Vista. I have a feeling it may be malware causing this. I am out of solutions and really need some help with this.

Have you checked Proxy settings? Is this a business or home network?

'ping' uses a different protocol than web access and doesn't necessarily mean the web site is working.  Can you get to any web site with just an IP address?

I have not checked the proxy settings. How do I do that? It also a home network. I have not tried to use an ip address. Do I do this from the command prompt or in IE?

If it's a home network, don't worry about the proxy options.
Find an ip address of the website: from
Command prompt type: "ping -a websitedomain" obviously without "'s and replace websitedomain with the address. This should resolve the address to an IP address that you can then Ping.

I had already figured that out and I tried it. I got 4 replies.

No, put the IP address in your browser address bar like "http://123.123.123.123"

It seems that the computer you are using is infected from some virus which is not letting to browse the internet.

I tried malware and it found nothing. I also just tried to install spybot and it could not complete as it was unable to establish a connection to the server. I will try the others you suggested and post back. Thanks.

While scanning with Hitman it said IE is using a proxy server on this computer to the internet. What does this mean?
Sudeep SharmaTechnical Designer

Commented:
Open IE, click on Tool --> Internet Options  --> Click on Connections --> LAN Settings. Remove all the Check boxes you could find in there. That would remove any proxy settings.

I think that would be the problem that you were not able to browse the internet.

Did you just uninstall Norton Internet Security?  If you did, then you need to get the Norton Removal Tool which actually does remove the stuff the uninstaller leaves behind.   http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20080710133834EN&ln=en_US

Do you know how that happened all of a suddden?

Anti-virus programs use a proxy server on your computer to intercept internet traffic and email so they can check it before you get it.  Norton often leaves the proxy in place after it is uninstalled.  I would still keep an eye out for malware.
