I have a PC that has Windows XP SP2 on it. It had IE6 on it and started giving the 400 error for any website that I visited. I installed Ad-Aware and had Avast running on the PC. I cleaned up all the Malware on the PC and Avast didnt find any viruses. I installed Kaspersky and that found a couple Trojans that got deleted.

I updated to IE8 and still have the same issue. I disabled the firewall and still no go. I installed Firefox and that works just fine. Now I'm stumped.

Any help/ideas would be appreciated.

Hi,

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. (see Note below)
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Thing I've also noticed is when I first launch IE, it only takes 3-4 seconds for the "page cannot be displayed" message to come up. If I type in another address, the browser just sits at "connecting".

Here is the full scan:

I have Kaspersky 8.0.9 installed so the online scan will not work. Do you want a scan from the installed client?

Do you get the error on every website?

Try this:

We need to repair some of windows' internal registration settings
  • Please download Dial-A-Fix from one of the following mirrors:
  • Extract the zip file to your desktop.
  • Double click Dial-a-Fix.exe to start the program.
  • Press the green double checkmark box (Looks like this: Posted Image)
  • UNcheck "Empty Temp Folders", as well as "Adjust Time/Date" in the prep section. The prep section should then look like this:
    Posted Image
  • When the window looks like this, press the GO button in the bottom of the window.
    Posted Image
  • Exit/Close Dial-A-Fix
Does this help?

Well I was able to try it tonight and there were some pop-up errors on some DLL's. It was not recognizing them because I upgraded to IE 8. But after running the fix I still cannot view any website in IE.

I've now reverted back to IE 6 and when I launch IE (with the home page set to Google) it says that the web site is found in the status bar, but it times out and gives Page cannot be displayed message. But at least I'm not getting the 400 Bad Request error.
