Advertisers taking over my screen when I'm on email

When I'm using email, Iget advertisers taking over my screen.  Once I've deleted them I have to relog into my email to carry on from where |I was interrupted.  This has only started today 16/11 but happens every few minutes.  I've never had this issue before.  How do I get rid of the interruptions?
