Adware is software that shows unwanted ads. Adware does not aim to break the device but it is quite harmful in other ways:
Ad Spam Makes User’s Internet Experience Awful
Users have to close numerous pop ups and sometimes they are unable to read the content of web pages because it is hidden behind ad banners.
It Slows Down Pages’ Loading Speed
On top of heavy page content, there are also dozens of ads to load, some of them having enormous image sizes or being in the video format.
It Collects User’s Information without Their Permission
Adware rarely shows irrelevant ads. It analyzes your Internet behavior and searches history to show ads that you may be interested in. However, it happens without your permission and this information may be used elsewhere.
It May Cause Crashes
A computer is working overtime to load all the ads coming your way and adware uses a lot of its memory. Therefore, users report slow work across the system and often program and computer crashes.
Adware can infect both mobile devices (tablets, smartphones) and computers. Users get adware while downloading free files or visiting sketchy websites.
