Your having problems getting online. Your hardware is working, a wireless router is working, and an Internet connection is working. You think it is a configuration issue with your browser and anti-virus software.
Please advise what a next step would be. Also you have Safari and Internet Explorer and both give a “cannot display the webpage” error message. You tested it on various websites, same error on all. Your other laptop is working with a very same internet connection, wifi router, etc.
So it is not a router and all diagnostics run fine. You are using Microsoft Windows Vista. Antivirus is Norton Internet Security and Norton Security Scan.
Click “Start” then select “Control Panel. Go into “Internet Options” then to “Connections” tab. Select “Lan Settings” and all you do is unclick the proxy server dialog box (use a proxy server for your LAN).
Now try to browse a web site. Another option is to clear your DNS cache.
1. Click a Microsoft Vista Start logo in a bottom left corner of your screen
2. Click All Programs
3. Click Accessories
4. RIGHT click on Command Prompt
5. Select Run As Administrator
6. In a command window type a following and then hit enter: ipconfig /flushdns
7. You will see a following confirmation:
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.
Try browsing a web site. If still not working try some Norton Internet Security steps. Temporarily turn off your firewall (for a brief test).
Start Norton Internet Security. In a Network pane, next to Smart Firewall, click a status indicator to turn it Off. In a Protection Alert dialog box, from a drop-down menu, select Permanently, and then click OK.
Restart your computer. Check Internet connectivity. Start your browser.
Connect to a following Web site:
Check whether you can access that Web site. At this time, you access the Internet with a firewall turned off. Do not access any other Web site now.
Troubleshooting steps depend on whether you can access the Symantec.com Web site with a firewall turned off. Before you proceed with some troubleshooting steps, you need to turn back your firewall on. Go to Step 3.
You don’t have to reinstall Norton Internet Security if you don’t want to. At least try to use their removal to make sure you have everything removed. You can cancel the reinstall when it prompts you to.To fix this problem, uninstall and reinstall Norton Internet Security 2010. Download and run the Norton removal tool to uninstall Norton Internet Security 2010. We recommend that you download the Norton Removal Tool on another computer which has an active Internet connection, and then transfer it to your computer using removable media such as USB drives, external hard drives, etc.
Click on “Download” button on ensuing web page after clicking download link above. On the Windows desktop, double-click the Norton Removal Tool icon. Follow the on-screen instructions.
Restart your computer. Instructions to reinstall your Norton products will be provided after the computer restarts. Your computer may be restarted more than once, and you will be provided the instructions on how to reinstall your Norton product.
Another option is to boot your computer into Windows safe mode with Networking support. Press your F8 key after your computer powers on. An advanced options window will open. Choose “Safe mode with networking support”.
Try to download and install Malwarebytes. Update malwarebytes and then run a full scan. Hopefully, you will be able to access the web.
You might need to disable your antivirus software if it is still installed. You can remove that as well while in safe mode.
I would run a full scan with both Malwarebytes and your Norton Antivirus if it is still installed. Make sure that both those program’s databases are updated. Also, you download and install CCleaner. Clean your PC with it first.
Also, clean your registry with CCleaner. Make sure CCleaner’s database is updated before running scans. If your still not able to access Internet in normal mode then click “Start” then select “All Programs”.
Choose “Accessories” then select “Command Prompt”. At command prompt type “ipconfig /release” (not the quotes) and then press your Enter key. Type “ipconfig /renew” and Enter. Probably best to do this in Safe Mode although it shouldn’t make any difference.
If you get any error messages when doing this, navigate to a following URL which walks you through the steps on “How to determine and recover from Winsock2 corruption”.

Another option is to perform a Windows Vista system restore. Basically you pick a restore point to a date before you started having this problem and restore Windows.
Open System Restore by clicking your Start button, clicking All Programs, clicking Accessories, clicking System Tools, and then clicking System Restore.?
If you are prompted for an administrator password or confirmation, type the password or provide confirmation. Hopefully, that will fix your problem.
interesting post, pretty much covered it all for me, thanks.
Glad you found it useful.
