I do not believe that Constant Fun ads are powered by the websites that I visit. There must be a malicious application that is lurking on my system and sending these fake ads. I call them fake, because when I click on them, I get redirected to suspicious web sources that do not seem to be reliable! They frequently offer me to install free programs, but I believe I will infect my computer if i agree to install them. What should I do to stop Constant Fun ads? I want to secure my computer.
