internet explorer script error

After starting up Avast, I check the box to “Don’t show this window next time” on the simple user interface window, I recieve a internet explorer script error. Please Help. I would include a screenshot of my problem but for some reason I can’t seem to attach my jpg file. Sorry.

 Hey thanks a lot, I did what the article said and I’m now all fixed, I really appreciate it.  Thanks again!
