I keep getting pop ups about ‘go.wvydeo.com’. Sometimes I’ll have a browner open, sometimes not. And sometimes I’ll be working for a long time before I get the Avast pop up, then I’ll get several within a couple of minutes. How can I stop this? I’ve run Avast, Piriform CCleaner, Spyhunter, and Malwarebytes and nothing has stopped this. Please help!
