Every time I do a google search when I click on the hyperlinks it sends me to various ad sites. Occasionally when i open my browser it opens a pop up to survey sites. I have removed my old anti virus software and installed VIPRE. I have also run Malwarebytes they found infections and removed them but the problem persists. Now when I run both scans they don't find anything. Please let me know how to fix this problem. Thank you in advance
