Avast warning about malicious pages

I downloaded avast and malwarebytes anti-malware. In the first scan with the malwarebytes the computer had a lot of viruses, now it says that is clean but when I’m using the internet there is a lot of pop ups and blinking announcement and every time I click to move the page up or down it causes to open up other pages and that is when I’m getting the Avast warning about the malicious pages. What can I do to stop those pages to be opening up all the time and to take all those announcement out??? Thank you :slight_smile:
