This document explains a workaround if you receive 'A Runtime Error has occurred. Do you wish to Debug?' when attempting to load a webpage in Internet Explorer.
Note: This workaround may not work in all cases. We do not have another reliable method to offer at this time.
When attempting to load a webpage you receive one of the following error messages:

Note: Some users have reported that after trying the above steps they discovered the problem was malware related. So if all the previous steps fail you should run a full virus scan.
