Internet script errors occur when the web page maker's programming contains an error; an antivirus program or adware removal program detects spyware or adware, which causes the page to stop loading that component of the webpage; or a pop-up on a web page does not load because of the computer's security settings. The average computer user cannot fix Internet Explorer script errors, but you can avert script errors by changing your Internet Explorer settings.
Double click on Internet Explorer.
Click on "Tools" and the "Internet Options" in the top left menu.
Click on the "Advanced" tab.
Click the box next to "Disable Script Debugging" to turn it on.
Click the box next to "Display a notification about every script error" to turn it off.
Click the "OK" button in the bottom right of that menu.
Close all open Internet Explorer windows and open new windows to restart the program with the new settings.
If you are still getting script errors, check for and install any Windows Updates from Microsoft. Updating Internet Explorer from Microsoft's website will remedy some of the script errors. If there are still errors after updating the computer, check some of the programs like adware removal software or antivirus software that could be causing the errors and change the settings to ignore scripts.
Adware and viruses can cause script errors. Run adware removal and virus removal software often to prevent the errors. There is a known bug within Windows XP Service Pack 2 that can randomly cause a script error. If Windows Update does not fix the issues, the only way to bypass them is to exit out of the error screen.
