I keep getting this error message randomly: "Stop running this script? A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive." I scanned different help websites. I have downloaded Firefox and have been using that for the past couple of days but I am still getting this error message. I don't know why since I am not even using Internet Explorer anymore. Firefox is set as my default browser. Any suggestions on how to get this message to stop popping up?

First, boot into safemode with networking via F8 at startup and do an adware and virus scan and verify your machine is clean.

Then, the error may be unrelated to actual web browsing with IE. Many applications use IE components to render HTML content, and it might be caused by these and not IE proper. Does the appearance of the issue coincide with installation or removal of any software?

I have "Windows Live OneCare" and it doesn't appear to allow me to run a scan in SafeMode. I did run a full scan yesterday and everything appeared clean. Do you recommend getting an additional Adware program? OneCare claims to address these issues but maybe they don't. I don't think the problem coincides with the installation or removal of software. I have not removed any software recently and I do not believe I (knowingly) added any.

Never hurts, not everyone detects everything. Ad-Aware or Spybot-S&D are free.

See How to troubleshoot script errors... and try updating Java. You can use Process Explorer to attempt to determine what process is running a script or disable scripting entirely on IE's Tools > Options > Security Tab for all the zones and see what breaks.

If none of the above has any affect, you can always call Microsoft Product Support and pay for an incident.
