Security Center / Definitions / Adware


Adware displays advertising banners or pop-ups on your computer when you use an application. You may consider some adware to be of value. For example, some free Android apps and browser toolbars are funded by adware. Adware becomes a problem, however, if it installs itself on your computer without your consent or installs itself in applications other than the one it came with and displays advertising when you use those applications. Sophos Home detects adware and reports it to you as a potentially unwanted application (or PUA). You can choose to either authorize the adware program or remove it from your computer.
