I have a desktop computer-broadband is wireless (connected with yellow cable).
Occurs in both Internet Explorer and Microsoft Edge.
I only use Edge
I have tried to change the Home pages but Yahoo keeps returning. I went into Internet Options and changed it to default, When I tried to go back on line the setting had reverted back to the Yahoo setting.
Every time there is movement on the internet such as you asking me a question the screen fills with adverts, an typing the reply is a long process.
I have resolved the issue via remote support. If you need help with anything else, please come back any time. Thank you very much.
