help please!

when going to some websites i get all these:

"A runtime error has occured
do you wish to debug?

line 1579
error: object expected"

what are these and how do i get rid of them?
thanks

Could be an error on the particular site but more than likely a software problem at your end. Try upgrading your IE or if you have the latest version, repair via control panel, add/remove programs.
