What is ContentStyles?

ContentStyles is another adware that can infiltrate your computer via fake Adobe updates or software bundles. It is used for advertising purposes and link promotion. As a result, countless annoying pop-up ads that will appear from time to time while browsing the Internet. One of the signs of its infiltration is a pop-up stating that Apple wants to make changes and requests your password. If you click “Cancel” button, you will see a new pop-up: “installation complete” with the only choice is to click “OK”.

ContentStyles can also change homepage, new tab page or default search engine of a browser and take measures to prevent users from changing those settings back. Hence, we advise you to get rid of ContentStyles as soon as possible.
