So what can Adware do?
The real threat of Adware goes far beyond just displaying pop-up ads, changing your browser’s homepage, or redirecting your web browser to unwanted websites full of advertisements.

- Cost you money from excessive data – downloading images and videos displayed in the ads can be costly to your data charges.
