Error Message?

I get this error message when i click on a link in my tiscali email, TB has caused an error in unknown and will now close, When i click on close it closes the previous page down, it does the same with any link after that, If i go to Tiscali through Internet Exp i dont get the message, i cant find any settings in Tiscali to stop it, I have Windows ME, Avast anti virus, Spyware doctor, Zone alarm, Adaware, A2 squared, all show nothing, I would appreciate any help.
