Download and use malwarebytes to find out what your PC is infected with.

Thank you I have done that now as a trial to start, it is slightly better I can at least close them down as they appear now which I could not before ,but still happens

There is a free version so you need not have started a trial.

I am wondering if you are going to sites with dodgy advertising that does this. Malwarebytes usually fixes any infection problems. Maybe you keep getting reinfected ?

May be worth trying a free virus scan too. I've used the Trend one on occasion http://housecall.trendmicro.com/uk/
