The described effects could be observed in any browser compatible with Mac. Popular ones like Chrome, Safari, and Firefox are obviously the ones that get hit by this type of apps most frequently. If you are in need of help for the removal of this invasive app from your Mac, be sure to finish reading this article and then head down to the removal instructions we have posted ad the bottom of this page.
